Server Quality Checklist
Latest release: v0.1.0
- Disambiguation5/5
Each tool has a distinct function: indexing, context retrieval, listing chats, full-text search, semantic search, syncing, and transcription. No two tools overlap in purpose.
Naming Consistency3/5Naming is a mix of English and Russian, and patterns vary: verb_noun (list_chats), verb_adverb (sync_now), adjective_noun (semantic_search). All use snake_case, but the inconsistency reduces predictability.
Tool Count5/5Seven tools is appropriate for the server's purpose of searching and analyzing Telegram messages. Each tool provides necessary functionality without excess.
Completeness4/5Core workflows (indexing, searching, syncing, transcription) are covered. Missing explicit get/export message operations, but the set is largely complete for its intended use.
Average 3.6/5 across 7 of 7 tools scored. Lowest: 2.4/5.

How to sync the server with GitHub?
Servers are automatically synced at least once per day, but you can also sync manually at any time to instantly update the server profile.
To manually sync the server, click the "Sync Server" button in the MCP server admin interface.
How is the quality score calculated?
The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).
Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.
Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).
Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.
Tool Scores
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It only says 'full-text search over indexed Telegram messages', failing to disclose that it is a read-only operation, what the search scope is (e.g., message text only), or any behavioral traits like rate limits or pagination.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise (one sentence) and front-loaded with 'Full-text search', but it is too brief, sacrificing necessary detail. Every sentence should earn its place; this one does not provide enough information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has 5 parameters and an output schema, but the description fails to mention filtering options, return behavior, or any context. It is incomplete for a search tool of this complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, yet the description adds no meaning to any of the 5 parameters. It does not explain the 'query' parameter, date range filters, chat filter, or limit. The agent must rely solely on parameter names.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool performs full-text search over Telegram messages, which is a specific verb-resource combination. It also distinguishes from the sibling tool 'semantic_search' by specifying 'full-text'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like 'semantic_search'. There is no mention of prerequisites, limitations, or context for usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description does not disclose any behavioral traits such as message ordering, size limits, or whether it returns only immediate neighbors. The agent is left to guess behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Single, clear sentence that efficiently conveys the purpose. Could be longer to add missing details, but no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 3 parameters and an output schema, the description provides insufficient context. The meaning of 'window' and the structure of returned messages are absent, leaving the agent underinformed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. Description mentions chat_name and around_message_id implicitly but does not explain them. Parameter 'window' is not described at all. Output schema exists but is not referenced.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the verb 'Return' and the resource 'messages surrounding a specific message in a chat'. Differentiates from siblings like search_messages which finds messages by query, not context.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies usage when needing context around a message, but no explicit when-not or alternative tools are mentioned. Sibling tools like search_messages could serve similar purposes, but no guidance on selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It discloses the action (force sync) but lacks details on side effects, idempotency, or safety. For a potentially impactful operation, more behavioral context is needed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no extraneous text. It is front-loaded and concise, conveying the essential information efficiently.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with no parameters and an output schema, the description covers the basic function. However, it omits behavioral details (e.g., idempotency, rate limits) and usage guidance, leaving gaps for an agent to decide when to invoke it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has no parameters, so the description adds value by specifying the scope ('all whitelisted chats'). This clarifies what the tool operates on, which is not evident from the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's action: forcing an incremental re-sync of all whitelisted chats. The verb 'sync' and resource 'whitelisted chats' are specific, and the tool is distinct from its siblings (which involve embedding, listing, searching, etc.).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, appropriate context, or when not to use it. The agent must infer usage from the tool name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description implies read-only behavior but does not explicitly state it. The term 'whitelisted' is mildly ambiguous. Adequate for a simple list tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no extraneous words. Highly concise and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters and an output schema, the description is reasonably complete. Could mention pagination or sorting, but not strictly necessary.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist, but the description adds meaning by specifying what is listed ('with message counts and last activity date'), which goes beyond the empty schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists 'whitelisted chats' with specific details (message counts and last activity date), distinguishing it from siblings like get_chat_context or search_messages.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool over alternatives such as search_messages or get_chat_context. The description lacks context for appropriate invocation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Since no annotations are provided, the description carries full burden. It discloses prerequisite indexing steps and the conditional behavioral difference between whitening-trained fallback and raw nomic, which is good transparency for a read-only search tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two concise sentences, front-loaded with the main purpose. The second sentence contains technical detail that, while valuable, could be daunting for some agents. Overall efficient with no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, the description does not need to explain return values. It covers the core behavior, prerequisites, and algorithmic fallback. Missing is the role of 'chat_name' and the effect of 'limit', but these are minor gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% and the description adds no parameter-level details. It does not explain 'query', 'limit', or 'chat_name' beyond the schema defaults and types, leaving the agent to guess their semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it searches messages by meaning using embeddings, not exact words. It explicitly distinguishes from sibling 'search_messages' (exact match) by contrasting semantic vs. exact search.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context: use for semantic search when exact word search is insufficient. It mentions prerequisites (embed_index) and fallback behavior, but does not explicitly name the sibling tool for exact search as an alternative.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses batch processing, need for repeated calls, and that it only processes messages without vector. However, it does not mention side effects, idempotency, or error handling, but the key behaviors are covered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Three short, efficient sentences in Russian. Front-loaded with purpose, then usage, then alternative. No fluff, every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers main purpose and usage pattern, but lacks return value structure (only mentions has_more flag, not how to access it) and prerequisites. Without output schema, description should provide more detail on what the tool returns.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has one optional parameter 'batch' with default 300, but schema description coverage is 0%. The description says 'one batch' implying batch size, but does not explicitly link the parameter name to its meaning. An agent can infer, but it's not explicit.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool indexes one batch of messages without vector (generates embeddings). It distinguishes from siblings like search_messages or semantic_search by focusing on batch indexing rather than retrieval or synchronization.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicit guidance: 'Call repeatedly while has_more=true' and mentions alternative scripts/embed_backfill.py for full reindexing. This helps an agent decide when to use this tool versus alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Despite no annotations, the description comprehensively discloses behavior: it uses Telegram's built-in transcription, requires Premium, modifies messages.text, affects downstream features (search, embeddings, bursts, topics), and returns a specific object. No annotation contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no redundancy, front-loaded with action and resource. Every sentence adds necessary information (prerequisite, effect, output).
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with one simple optional parameter and an output schema, the description provides all necessary context: what it does, prerequisites, side effects, and return shape. No gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter 'limit' is not mentioned in the description, and schema coverage is 0%. While the parameter is self-explanatory, the description should have clarified its purpose (e.g., limits number of messages to transcribe) to add value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('transcribe') and the specific resource ('pending voice/video-note messages'). It distinguishes from sibling tools, which focus on indexing, search, or syncing, not transcription.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description mentions the requirement for a Premium account and that transcripts are written into messages.text. It implicitly tells when to use (to transcribe pending voice notes), but does not explicitly tell when not to use or provide alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
