DeepSearch MCP
Server Quality Checklist
Latest release: v1.0.0
- Disambiguation4/5
The two tools are mostly distinct (one for broad search, one for site/time-targeted search), but both share the 'deepsearch' prefix and perform search operations, which could cause some confusion for an agent.
Naming Consistency5/5Both tools follow a consistent 'deepsearch' prefix pattern, with the second adding a '-web' suffix to indicate specialization. Naming is predictable and clear.
Tool Count2/5With only 2 tools for a search-focused server, the surface is extremely thin. A typical search server would require more tools for different query types, result handling, or configuration.
Completeness2/5The server only offers two search variants, lacking obvious features like result retrieval, pagination, search history, or advanced filters. This is severely incomplete for a search domain.
Average 3.1/5 across 2 of 2 tools scored.

This repository is licensed under Apache 2.0.
This repository includes a README.md file.
No tool usage detected in the last 30 days. Usage tracking helps demonstrate server value.
Tip: use the "Try in Browser" feature on the server page to seed initial usage.
Add a glama.json file to provide metadata about your server.
If you are the author, simply .
If the server belongs to an organization, first add
glama.jsonto the root of your repository:{ "$schema": "https://glama.ai/mcp/schemas/server.json", "maintainers": [ "your-github-username" ] }Then . Browse examples.
Add related servers to improve discoverability.
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?
No annotations provided, so description bears full burden. It only mentions time-consuming nature. Lacks details on authentication, rate limits, or behavioral side effects. Minimal transparency.
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 sentence, front-loaded with core action. Efficient and to the point. 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 4 parameters, no schema descriptions, and no output schema? Actually there is an output schema, but description only says 'structured results'. Missing details on parameter usage and result format. Incomplete for effective tool use.
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 coverage is 0% and description adds no parameter-specific information. The query parameter is implied but not explained. No guidance on top_k, locale, or filters.
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?
Description clearly states it uses DeepSearch model for broad search and returns structured results. It compares to built-in search, indicating its scope. However, it does not explicitly distinguish from sibling deepsearch-web.
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?
Description provides trade-off guidance: better results but more time-consuming, advising balance. This helps decide when to use vs. built-in search. No explicit exclusion or alternative mention for sibling.
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 are provided, so the description must cover behavioral traits. It only notes the tool is slower, but does not disclose whether it is read-only, destructive, or other side effects. There is no mention of authentication or rate limits.
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 a single sentence, which is concise but lacks structure. It does not use bullet points or separate sections for clarity, and it omits important details that could be included without much length.
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 complexity of 4 parameters including a nested object, and the presence of an output schema, the description is insufficient. It does not describe the output format, provide usage examples, or cover all parameters adequately.
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 schema has 0% description coverage, so the description must compensate. It only hints at filters for site/time range, but does not explain query, top_k, locale, or the structure of the filters object. Users are left to infer parameter meanings from names alone.
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 is a targeted search for site or time range, and contrasts with built-in AI agent search in terms of quality and time cost. It distinguishes from sibling 'deepsearch' by implying this is more specialized.
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?
The description mentions it is more time-consuming but better, implying use when quality is preferred over speed. However, it does not explicitly state when to avoid using it or directly compare to the sibling tool 'deepsearch'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
