google-workspace-unlimited
🚀 Plataforma Google Workspace de GoogleUnlimited
GoogleUnlimited es un framework MCP integral que proporciona una integración perfecta con Google Workspace mediante una arquitectura de middleware avanzada. Permite a los asistentes de IA y a los clientes MCP interactuar con los servicios de Gmail, Google Drive, Docs, Sheets, Slides, Calendar, Forms, Chat, Photos y Contacts (People API) mediante una API unificada y segura.
Lo que lo hace diferente:
⚡ Code Mode por defecto — en lugar de inundar tu cliente con más de 90 esquemas de herramientas, el servidor expone 7 metaherramientas ligeras; la IA descubre las herramientas bajo demanda y encadena llamadas reales a la API dentro de un único bloque
executeen espacio aislado🚀 Arranque sin configuración — el servidor se ejecuta inmediatamente sin archivo
.env; OAuth se realiza de forma diferida en el primer uso🔧 Control de herramientas por sesión — filtrado de servicios basado en URL y habilitación/deshabilitación con ámbito de sesión, de modo que cada cliente conectado ve exactamente las herramientas que necesita
🎨 Sistema de DSL de plantillas y tarjetas — las macros de Jinja2 y una notación compacta de tarjetas convierten los datos brutos de la API en correos electrónicos enriquecidos, paneles y tarjetas de Google Chat
🧠 Memoria semántica — cada respuesta de herramienta se incrusta en Qdrant y se puede buscar posteriormente con lenguaje natural

¿Qué es GoogleUnlimited?
GoogleUnlimited proporciona a los asistentes de IA acceso a los servicios de Google Workspace a través del Model Context Protocol (MCP). Admite más de 92 herramientas en 9 servicios de Google, lo que permite una integración perfecta entre los flujos de trabajo de IA y las aplicaciones de Google Workspace con mejoras de rendimiento revolucionarias.
🛠️ Métodos de instalación
Método 1: Instalación rápida mediante uvx (recomendado)
La forma más rápida de empezar: instala directamente desde PyPI:
{
"mcpServers": {
"google-workspace-unlimited": {
"command": "uvx",
"args": ["google-workspace-unlimited"],
"disabled": false,
"timeout": 300
}
}
}⚡ ¡Eso es todo! El servidor se ejecuta en modo stdio por defecto, perfecto para clientes MCP como Claude Desktop, Cursor, Roo, etc. Code Mode está activado de serie, por lo que tu cliente ve 7 metaherramientas ligeras en lugar de más de 90 esquemas.
Método 1b: Plugin de Claude Code (servidor + habilidades)
Los usuarios de Claude Code pueden instalar el servidor y las habilidades que enseñan a Claude su DSL de tarjetas/correos, Code Mode y la búsqueda en Qdrant con dos comandos:
/plugin marketplace add dipseth/google_workspace_fastmcp2
/plugin install google-workspace-unlimited@riversunlimitedConsulta plugins/google-workspace-unlimited para más detalles.
Método 2: Clonación y configuración de desarrollo
Para desarrollo o personalización:
Clona y configura:
git clone https://github.com/dipseth/google_workspace_fastmcp2.git cd google_workspace_fastmcp2 uv syncInicia el servidor:
uv run python server.pyEl servidor se inicia inmediatamente sin necesidad de configuración. No se necesitan credenciales OAuth al arrancar: la autenticación se gestiona de forma diferida cuando interactúas por primera vez con un servicio de Google.
Autentícate cuando estés listo:
Cuando llames a cualquier herramienta de Google Workspace, el servidor te pedirá que te autentiques mediante la herramienta
start_google_auth. Esto abre un flujo OAuth basado en navegador. Una vez completado, las credenciales se almacenan localmente y se reutilizan entre sesiones.Para preconfigurar las credenciales OAuth (opcional), crea un archivo
.env:cp .env.example .envLuego añade tus credenciales de Google Cloud Console:
# Option A: Client ID + Secret GOOGLE_CLIENT_ID=your-client-id.apps.googleusercontent.com GOOGLE_CLIENT_SECRET=your-client-secret # Option B: Downloaded JSON credentials file GOOGLE_CLIENT_SECRETS_FILE=credentials.jsonConsulta los pasos de configuración de Google Cloud Console para crear credenciales OAuth y habilitar las API.

🔗 Conexiones de clientes
GoogleUnlimited admite múltiples métodos de conexión. Estas son las dos formas más populares de empezar:
🎯 Opciones de Configuración Rápida
Opción 1: Cursor IDE (STDIO - Verificado por la Comunidad ✅):
{
"mcpServers": {
"google-workspace": {
"command": "uv",
"args": [
"--directory", "/path/to/google_workspace_fastmcp2",
"run", "python", "server.py"
],
"env": {
"GOOGLE_CLIENT_SECRETS_FILE": "/path/to/client_secrets.json",
"MCP_TRANSPORT": "stdio"
}
}
}
}Opción 2: HTTP Streamable (VS Code Roo, Claude Code, Claude Desktop, etc.):
# Start server in HTTP mode
uv run python server.py --transport http --port 8002Configuración básica de conexión única:
{
"google-workspace": {
"type": "streamable-http",
"url": "https://localhost:8002/mcp",
"disabled": false
}
}Configuración multi-conexión — conecta el mismo cliente (o varios clientes) al mismo servidor con diferentes conjuntos de herramientas usando parámetros de consulta en la URL:
{
"google-email": {
"type": "streamable-http",
"url": "https://localhost:8002/mcp?service=gmail"
},
"google-chat": {
"type": "streamable-http",
"url": "https://localhost:8002/mcp?service=chat"
},
"google-productivity": {
"type": "streamable-http",
"url": "https://localhost:8002/mcp?service=drive,docs,sheets,slides"
}
}Cada conexión obtiene su propia sesión aislada con solo las herramientas de servicio solicitadas habilitadas. También puedes fijar un ID de sesión con ?uuid= para reanudar el mismo estado de sesión entre reconexiones:
{
"google-workspace": {
"type": "streamable-http",
"url": "https://localhost:8002/mcp?uuid=my-workspace&service=gmail,drive,calendar"
}
}Consulta Filtrado de Servicios por URL para ver la lista completa de parámetros de consulta.
🤖 Claude Code y Claude Desktop
Claude Code (CLI) — un solo comando, usando el paquete PyPI publicado:
# Local stdio (recommended): uvx fetches and runs the server on demand
claude mcp add google-workspace -- uvx google-workspace-unlimited
# Or connect to an already-running HTTP server
claude mcp add --transport http google-workspace https://localhost:8002/mcpClaude Desktop (ruta de desarrollo local) — añade a claude_desktop_config.json (Configuración → Desarrollador → Editar Config):
{
"mcpServers": {
"google-workspace-unlimited": {
"command": "uvx",
"args": ["google-workspace-unlimited"]
}
}
}Claude.ai / Claude Desktop (conector alojado) — ejecuta el servidor detrás de un endpoint HTTPS público (por ejemplo, un túnel de Cloudflare o ngrok), luego añádelo en Configuración → Conectores → Añadir conector personalizado con tu URL https://your-domain/mcp. El flujo OAuth 2.1 + PKCE del servidor gestiona la autenticación, incluida la redirección https://claude.ai/api/mcp/auth_callback. Consulta la Guía de Integración con Claude.ai para ver el tutorial completo.

⚡ Modo Código (Predeterminado)
El Modo Código es la función insignia de GoogleUnlimited — y está activado por defecto. En lugar de cargar más de 90 esquemas de herramientas por adelantado (costoso en tokens), tu cliente MCP ve solo 7 meta-herramientas. La IA descubre herramientas bajo demanda y luego encadena cualquier número de llamadas API reales dentro de un único bloque execute de Python en sandbox.
Meta-Herramienta | Propósito |
| Explorar herramientas por categoría de servicio (Gmail, Drive, Calendar, etc.) |
| Búsqueda de palabras clave con BM25 en nombres y descripciones de herramientas |
| Obtener esquemas de parámetros completos para las herramientas seleccionadas |
| Búsqueda en lenguaje natural sobre respuestas de herramientas almacenadas previamente (respaldada por Qdrant) |
| Recuperar una respuesta almacenada completa por ID de punto desde los resultados de búsqueda |
| Resumir patrones de uso recientes y actividad de herramientas |
| Ejecutar un bloque de Python en sandbox que encadena llamadas reales a herramientas mediante |
Por qué es importante:
💰 Ahorro masivo de tokens — 7 esquemas en lugar de más de 90, con esquemas completos obtenidos solo para las herramientas realmente utilizadas
🔗 Un solo viaje de ida y vuelta en lugar de muchos — buscar → filtrar → actuar ocurre dentro de un único bloque
execute, no en una cadena de viajes de ida y vuelta del cliente🧰 Sandbox con todo incluido — más de 40 ayudantes integrados (
now(),days_ago(),to_json(),re_find(),gather_tools(), …) cubren fechas, JSON, URLs, regex, matemáticas y llamadas por lotes sin necesidad de importaciones
# One execute block: find a Drive file, then email its link
files = await call_tool("search_drive_files", {"query": "Q4 report"})
link = files["files"][0]["webViewLink"]
result = await call_tool("send_gmail_message", {
"to": "manager@company.com",
"subject": "Q4 Report",
"body": "Here's the Q4 report: " + link,
})
return result¿Prefieres el catálogo clásico? Opta por no participar y cada herramienta se expone directamente al cliente:
ENABLE_CODE_MODE=false # expose the full 90+ tool catalog insteadEl Modo Código y el catálogo clásico son mutuamente excluyentes — cuando el Modo Código está activo, las llamadas directas a herramientas se reemplazan por el patrón de búsqueda +
execute. Las herramientas de descubrimiento siempre ven el catálogo completo, independientemente del filtrado a nivel de sesión.

🔧 SessionToolFilteringMiddleware - Gestión de habilitación/deshabilitación de herramientas por sesión
🚀 Inicio con Herramientas Mínimas
Por defecto, GoogleUnlimited se inicia con solo 5 herramientas protegidas habilitadas para un rendimiento y seguridad óptimos. Esto permite a los clientes habilitar solo las herramientas que necesitan.
Herramientas Protegidas (Siempre Disponibles):
manage_tools- Habilitar/deshabilitar herramientas globalmente o por sesiónmanage_tools_by_analytics- Gestión de herramientas basada en análisishealth_check- Estado de salud del servidor y estado de configuraciónstart_google_auth- Iniciar autenticación OAuthcheck_drive_auth- Verificar estado de autenticación
Configuración:
# Default: Start with minimal tools (only 5 protected tools)
MINIMAL_TOOLS_STARTUP=true
# Optional: Pre-enable specific services at startup
MINIMAL_STARTUP_SERVICES=drive,gmail,calendar
# Disable minimal startup (enable all 92+ tools immediately)
MINIMAL_TOOLS_STARTUP=falseHabilitando Herramientas en Tiempo de Ejecución:
# Enable all tools globally
manage_tools(action="enable_all")
# Enable specific tools
manage_tools(action="enable", tool_names=["search_drive_files", "list_gmail_labels"])
# List all registered tools (shows enabled/disabled status)
manage_tools(action="list")🔧 Gestión de Herramientas con Alcance de Sesión
GoogleUnlimited admite la funcionalidad de habilitar/deshabilitar herramientas por sesión, lo que permite que diferentes clientes MCP tengan diferente disponibilidad de herramientas sin afectar a otros clientes conectados.
Características Clave:
Aislamiento de Sesión: Deshabilita herramientas para una sesión de cliente sin afectar a otras
No Invasivo: Las operaciones con alcance de sesión nunca modifican el registro global de herramientas
Herramientas Protegidas: Las herramientas de gestión centrales (
manage_tools,health_check, etc.) siempre permanecen disponiblesBasado en Middleware: Utiliza
SessionToolFilteringMiddlewarepara el filtrado a nivel de protocolo
Ejemplos de Uso:
# Disable tools for this session only (other clients unaffected)
manage_tools(action="disable", tool_names=["send_gmail_message"], scope="session")
# Disable all except specific tools for this session
manage_tools(action="disable_all_except", tool_names=["search_drive_files", "list_events"], scope="session")
# Re-enable all tools for this session
manage_tools(action="enable_all", scope="session")
# Global operations (original behavior, affects all clients)
manage_tools(action="disable", tool_names=["send_gmail_message"], scope="global")Estructura de Respuesta:
{
"success": true,
"action": "disable_all_except",
"scope": "session",
"enabledCount": 94,
"disabledCount": 0,
"toolsAffected": ["tool1", "tool2", "..."],
"sessionState": {
"sessionId": "f725be09...",
"sessionAvailable": true,
"sessionDisabledTools": ["tool1", "tool2"],
"sessionDisabledCount": 89
},
"message": "Kept 5 tools, disabled 89 tools for this session"
}📚 Proveedor de Habilidades
Cuando se habilita con ENABLE_SKILLS_PROVIDER=true, GoogleUnlimited genera documentos de habilidades a partir de instancias de ModuleWrapper y los sirve a través del SkillsDirectoryProvider de FastMCP. Las habilidades proporcionan conocimiento estructurado que los LLM pueden consultar para tareas complejas de múltiples pasos.
Módulos actualmente compatibles:
card_framework→ habilidadgchat-cards(referencia del DSL de tarjetas de Google Chat, jerarquía de componentes, ejemplos)
Configuración:
ENABLE_SKILLS_PROVIDER=true # Enable skill generation
SKILLS_DIRECTORY=~/.claude/skills # Output directory (default)Las habilidades se regeneran automáticamente en cada inicio y están disponibles inmediatamente a través del sistema de habilidades de FastMCP.
🖥️ Panel de Gestión de Herramientas
GoogleUnlimited incluye un Panel de Gestión de Herramientas integrado que se sirve a través del esquema de recursos ui:// de las Apps MCP. Esto proporciona una interfaz visual para monitorear y gestionar la disponibilidad de herramientas entre sesiones.

Características:

Available Tools
7 toolsexecuteExecuteA
Run sandboxed Python that calls this server's Google Workspace tools via await call_tool(tool_name, params), chaining calls in one block.
Use when: you know which tools to call. To find tool names first use search or tags; for exact parameters use get_schema; to look up past results instead, use semantic_search.
Behavior: each call_tool runs the real tool immediately — sends, edits, and deletes take effect; there is no dry-run.
Use return to produce output; prefer returning the final answer from a single block.
Only call_tool(tool_name: str, params: dict) -> Any is available in scope. Unknown tool names raise NotFoundError; disallowed syntax raises SandboxError.
SANDBOX RESTRICTIONS — these produce SandboxError, avoid them:
sorted_(items, key=lambda x: x['k'])→ lambda args fail; use builtins likekey=lenor sort manuallyimportonly covers a small stdlib subset (e.g. json); no third-party modules — prefer the built-in helpers listed below
Built-in helpers (import is not available — use these instead):

| Name | Required | Description | Default |
|---|---|---|---|
| code | Yes | Python async code to execute tool calls via call_tool(name, arguments) |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden, and it does so thoroughly. It discloses that each call_tool runs the real tool immediately with sends/edits/deletes taking effect and no dry-run, plus sandbox restrictions, error types, and disallowed syntax. This is substantial behavioral context beyond what the schema provides.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is long but well-structured with clear sections: use-when, behavior, sandbox restrictions, and built-in helpers. Core usage and side effects are front-loaded, and every block provides actionable information rather than filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that annotations and an output schema are absent, the description is remarkably complete. It covers selection criteria, invocation syntax, execution environment, side effects, error modes, restrictions, and helper APIs, so an agent can use this tool without needing additional documentation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already describes the single `code` parameter at 100% coverage, but the description adds far more semantic value: valid async syntax, `call_tool` signature, use of `return`, restrictions on `import`, sandbox errors, and a full list of available built-in helpers. This gives the agent everything needed to construct valid code.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description names a precise verb and resource: running sandboxed Python that calls this server's Google Workspace tools via `await call_tool(tool_name, params)` and chaining calls in one block. It also distinguishes itself clearly from discovery/search siblings by framing this as the execution step once tool names are known.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It gives an explicit 'Use when' condition: when you know which tools to call. It also names alternatives for other cases: `search` or `tags` for finding tool names, `get_schema` for exact parameters, and `semantic_search` for past results, providing clear routing to sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
fetch_documentFetch DocumentA
Preview one stored tool response by its Qdrant point ID.
Use when: inspecting a hit returned by semantic_search. To find
point IDs in the first place, use semantic_search; for the full
untruncated content, call the fetch tool inside an execute block.
Behavior: read-only. Returns: tool name, service, timestamp, user, argument count, and the first 500 characters of stored content. Errors: 'Document not found' for unknown or expired point IDs.
| Name | Required | Description | Default |
|---|---|---|---|
| point_id | Yes | Qdrant point ID (UUID) from a search result | |
| user_google_email | No | User's Google email (auto-injected by middleware) |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fully carries the behavioral disclosure burden. It states 'Behavior: read-only', describes the exact return fields including the 500-character truncation, and documents the error condition 'Document not found' for unknown or expired IDs. This is unusually transparent for a tool description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, well-organized with labeled sections, and front-loads the core purpose. Every sentence adds useful content, and there is no redundant repetition of schema or annotation details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite having no output schema, the description enumerates the return fields and truncation behavior, making the tool's output predictable. It also covers errors, read-only behavior, and usage context, making the description complete for an agent to select and invoke the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters clearly. The description adds context around the point_id's role in previewing a stored response, but does not need to add more because the parameter semantics are fully captured in the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific action ('Preview one stored tool response') and identifies the resource by 'Qdrant point ID', clearly distinguishing this from sibling search and execute tools. It also explicitly indicates what it is not for, such as full untruncated content, which further sharpens purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'Use when' section directly instructs to use this tool when inspecting a hit from semantic_search, and explicitly points to alternatives for finding point IDs and retrieving full content. This is exemplary routing guidance that leaves no ambiguity about when to use this tool versus siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_schemaGet SchemaA
Get parameter schemas for named tools before calling them via execute. Use when: you already have tool names (from search or tags) and need exact parameters. Not for discovery — use search for that. Returns: per-tool parameter markdown ('detailed', default), names + descriptions ('brief'), or full JSON schemas ('full'); unknown names are reported under 'Tools not found'.
| Name | Required | Description | Default |
|---|---|---|---|
| tools | Yes | List of tool names to get schemas for | |
| detail | No | 'brief' for names and descriptions, 'detailed' for parameter schemas as markdown, 'full' for complete JSON schemas | detailed |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses the output formats for each detail mode and the unknown-name handling behavior ('reported under Tools not found'). It does not explicitly state side effects, but the read-only nature is strongly implied by the verb 'get' and the schema-fetching purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is compact, front-loaded with the core purpose, and uses clear logical sections ('Use when', 'Not for discovery', 'Returns'). Every sentence earns its place without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is complete for a tool with no output schema and no annotations. It covers the main purpose, usage conditions, output formats, defaults, and error handling for unknown tool names. No critical operational gap remains for an agent deciding how to call this tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema coverage is 100%, so the baseline is 3. The description mostly restates what the schema already says about 'detail' and 'tools'; it adds minor value with 'per-tool parameter markdown' and unknown-name behavior, but does not substantially deepen parameter understanding beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb and resource: 'Get parameter schemas for named tools before calling them via execute.' It clearly differentiates from the sibling search tool by framing this as a pre-execute lookup step, not a discovery mechanism.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states when to use the tool ('when you already have tool names... and need exact parameters'), when not to use it ('Not for discovery'), and names the alternative ('use search for that'). This gives an agent unambiguous routing guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
searchSearchA
Find this server's Google Workspace tools by keyword (BM25 over names, descriptions, and tags). Use when: you don't know the exact tool name yet. To browse by category use tags; once you have names, use get_schema for parameters, then execute to call them. To search past results rather than tools, use semantic_search. Returns: matching tools as names + descriptions ('brief', default), parameter markdown ('detailed'), or complete JSON definitions ('full'). An empty result means no keyword match — retry with different terms.
| Name | Required | Description | Default |
|---|---|---|---|
| tags | No | Filter to tools with any of these tags before searching | |
| limit | No | Maximum number of results to return | |
| query | Yes | Search query to find available tools | |
| detail | No | 'brief' for names and descriptions, 'detailed' for parameter schemas as markdown, 'full' for complete JSON schemas | brief |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It does this well by revealing the BM25 ranking mechanism, the three return detail modes, the default 'brief' mode, and the meaning of an empty result ('no keyword match — retry with different terms'). This gives an agent a clear behavioral model beyond what the schema states.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is compact and well-structured. The primary purpose is stated first, followed by explicit usage guidance, sibling routing, and return behavior. Every sentence earns its place; there is no filler or repetition of schema details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a search tool with no annotations and no output schema, the description is thorough: it explains what is searched, when to use it, how to route to alternatives, what the return values look like in each detail mode, and how to interpret empty results. Nothing critical is missing for safe and correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all parameters clearly. The description adds a little context around the detail parameter's output modes, but most of what it says about parameters mirrors the schema. This meets the baseline but does not go substantially beyond it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a clear verb and resource: 'Find this server's Google Workspace tools by keyword,' and specifies the search mechanism (BM25 over names, descriptions, and tags). It also distinguishes the tool from siblings like tags and semantic_search, so an agent can immediately tell what this tool is for.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives explicit when-to-use guidance: 'Use when: you don't know the exact tool name yet.' It also names alternatives and the conditions for choosing them, such as using tags to browse by category, get_schema for parameters, execute to call, and semantic_search for past results. This is exemplary routing guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
semantic_searchSemantic SearchA
Search the Qdrant vector store of this server's past tool responses and card templates.
Use when: looking up previous results, usage history, or analytics ('service:gmail last week', 'tool:search recent', 'overview'). For discovering tools to call, use search; to preview one stored document, pass its point ID to fetch_document.
Modes: semantic text similarity; service/tool history queries; analytics ('overview', 'usage stats'); filter_dsl for structured filters; positive/negative point IDs for recommendation; query_dsl for fusion/discover/order-by; prefetch_dsl for multi-stage retrieval.
Behavior: read-only against the local Qdrant instance; no Google APIs are called. Returns: scored rows 'score service/tool timestamp id:'. Errors: 'Search failed' when Qdrant is unreachable; 'No results' when nothing clears score_threshold (default 0.3 — lower it to widen the net).
DSL filter symbols: D_5=DatetimeRange, ʄ=FieldCondition, ƒ=Filter, F_6=FilterSelector, ℏ=HasIdCondition, I_2=IsEmptyCondition, I_0=IsNullCondition, ɱ=MatchAny, ṁ=MatchText, M_0=MatchTextAny, ☆=MatchValue, ř=Range Query-DSL symbols: Å=AcornSearchParams, C_14=ContextExamplePair, ¢=ContextPair, C_0=ContextQuery, D_6=DiscoverInput, D_2=DiscoverQuery, D_4=DiscoverRequest, D_21=DiscoverRequestBatch, ℱ=Fusion, φ=FusionQuery, ø=OrderBy, ɵ=OrderByQuery, ¶=Prefetch, ʔ=QuantizationSearchParams, R_12=RecommendGroupsRequest, R_2=RecommendInput, R_4=RecommendQuery, R_5=RecommendRequest, R_18=RecommendRequestBatch, R_10=RecommendStrategy, ♦=SearchParams Example: ƒ{must=[ʄ{key="tool_name", match=☆{value="send_dynamic_card"}}]} MatchAny: ƒ{must=[ʄ{key="tool_name", match=ɱ{any=["tool_a", "tool_b"]}}]}
| Name | Required | Description | Default |
|---|---|---|---|

| positive_point_ids | No | Point IDs to use as positive examples for recommendation search |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. It explicitly states the tool is read-only, that no Google APIs are called, the exact return row format, the two error messages ('Search failed', 'No results'), and the effect of score_threshold. This is far more transparent than typical tool descriptions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured and front-loaded: purpose, use-when, modes, behavior, returns, errors, then reference material. It is long, but the DSL symbol tables and examples earn their place because the schema refers to 'see docstring for symbols.' A minor redundancy between the 'Modes' section and the query parameter description prevents a perfect score.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a complex 11-parameter tool with no output schema and no annotations, this description is remarkably complete: it covers return shape, error behavior, default threshold semantics, DSL syntax, example queries, sibling routing, and parameter mode mappings. An agent has nearly everything needed to invoke it correctly and interpret the response.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, giving a baseline of 3, but the description adds substantial meaning beyond the schema: a DSL symbol legend, a worked filter_dsl example, a MatchAny example, mapping of query_dsl/filter_dsl/prefetch_dsl to modes, explanation of positive/negative point IDs, and guidance to lower score_threshold. This meaningfully helps an agent construct parameters correctly.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description opens with a specific verb and resource: 'Search the Qdrant vector store of this server's past tool responses and card templates.' It also names sibling tools and clarifies what they do instead, so an agent can distinguish semantic_search from search and fetch_document without ambiguity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'Use when' section explicitly lists trigger conditions: looking up previous results, usage history, or analytics, with concrete query examples. It also provides exclusion guidance: 'For discovering tools to call, use search; to preview one stored document, pass its point ID to fetch_document.' This is exactly the when/when-not context an agent needs.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
tagsTagsA
List this server's tool tags (service areas like gmail, drive, docs, photos) with tool counts. Use when: browsing what capability areas exist before a targeted lookup. For keyword lookup use search; for parameters of known tools use get_schema. Returns: '- tag (N tools)' lines at detail='brief' (default), or every tool listed under each tag at detail='full'.
| Name | Required | Description | Default |
|---|---|---|---|
| detail | No | Level of detail: 'brief' for tag names and counts, 'full' for tools listed under each tag | brief |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden, and it does well: it specifies the exact output shape at default detail ('- tag (N tools)' lines) and the change at detail='full'. It clearly frames the operation as a non-mutating listing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Three compact sentences front-load the core action and use case before return details. There is no filler or unnecessary repetition of schema content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple list tool with one optional schema-defined parameter and no output schema, the description covers purpose, routing, default behavior, and return format. Nothing material needed to invoke it correctly is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already fully documents the single parameter with its enum, default, and per-value meaning, so the baseline is 3. The description adds the concrete output format for brief detail and confirms what full detail returns, which is a small but meaningful addition.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a precise action ('List this server's tool tags...') with resource and scope, plus concrete examples of categories like gmail, drive, docs, and photos. The mention of tool counts and the overview nature distinguishes it from sibling tools such as search and get_schema.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states the intended use case ('browsing what capability areas exist before a targeted lookup') and names alternatives for adjacent cases: 'For keyword lookup use search; for parameters of known tools use get_schema.' This gives an agent clear routing guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
tool_activityTool ActivityA
Show usage analytics for this server's tools: call counts, error rates, last-used times.
Use when: answering 'what has been used or failing lately'. To read an individual response, pass a sample point ID to fetch_document; to discover tools to call, use search instead.
Behavior: read-only aggregation over the Qdrant response store. Returns: a text dashboard grouped by tool_name or user_email, with sample point IDs per group. Errors: 'Analytics failed' when the response store is unreachable.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Maximum groups to show | |
| group_by | No | Group results by 'tool_name' or 'user_email' | tool_name |
| user_google_email | No | User's Google email (auto-injected by middleware) |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses read-only behavior ('read-only aggregation over the Qdrant response store'), return format ('text dashboard... with sample point IDs per group'), and an error condition ('Analytics failed' when the response store is unreachable). It does not mention authentication or rate limits, but for this tool the provided behavioral details are substantive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well structured with labeled segments ('Use when', 'Behavior', 'Returns', 'Errors'), front-loads the core purpose, and every sentence adds distinct value. No filler or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite having no output schema and no annotations, the description provides enough context for correct invocation: what it returns (text dashboard), how it groups, what error to expect, and when to use alternatives. All three optional parameters are already covered by the schema, so nothing needed for this tool is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so every parameter is already documented in the schema. The description mentions grouping by tool_name or user_email, which mirrors the group_by schema description, but does not add new semantic detail beyond that. Baseline 3 is appropriate when the schema handles parameter documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a specific verb and resource ('Show usage analytics for this server's tools: call counts, error rates, last-used times'), and later explicitly contrasts with fetch_document and search, distinguishing its purpose. An agent can immediately tell what this tool does and how it differs from siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Contains explicit 'Use when' guidance ('answering what has been used or failing lately'), plus clear redirections: 'pass a sample point ID to fetch_document' and 'use search instead'. This leaves no ambiguity about when to select this tool over alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 7 tools
The tools are mostly separable: tags and search provide different discovery paths, and semantic_search is clearly scoped to past responses. The main ambiguity is that search, semantic_search, and tags all surface tool/response names in slightly different ways, though the descriptions mitigate this by stating when to use each.
All names use lowercase with underscores, but the structural conventions are mixed: standalone verbs (search, execute), nouns (tags, tool_activity), and verb_noun compounds (get_schema, fetch_document) coexist. This is readable, but there is no single consistent naming pattern across the tool set.
Seven tools is an appropriate, well-scoped count for a discovery, schema, execution, history, and analytics server. Each tool carries a distinct responsibility, with no obvious redundancy or bloat.
The tool surface covers the core lifecycle of discovering tools, fetching schemas, executing calls, and retrieving historical results/analytics. Minor gaps exist, such as no dedicated tool for deleting/cleaning stored history or batch management of point IDs, but these are workable around.
