Discover Tools

discover_tools
Read-onlyIdempotent

Find tools by describing the data or task. Use when you need to browse, search, look up, or discover what tools exist for: SEC filings, financials, revenue, profit, FDA drugs, adverse events, FRED economic data, Census demographics, BLS jobs/unemployment/inflation, ATTOM real estate, ClinicalTrials, USPTO patents, weather, news, crypto, stocks. Returns the top-N most relevant tools with names, descriptions, and full input schemas (with curated examples) — each result is ready to call directly, no second schema lookup needed. Call this FIRST when you have many tools available and want to see the option set (not just one answer).

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds worthwhile behavioral context beyond annotations: it promises 'top-N most relevant tools with names, descriptions, and full input schemas' and notes results are 'ready to call directly, no second schema lookup needed.' This discloses return format and efficiency without contradicting the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is 3 sentences: purpose, usage guidance, and return behavior. It is front-loaded with the primary action ('Find tools'), and every sentence earns its place. No redundant phrases or qualifications. It is compact yet information-dense.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no output schema, the description adequately explains what is returned (tool names, descriptions, full input schemas). It also covers purpose, usage context, and a direct call-to-action. Minor gaps like 'relevant' ranking criteria or default limit (found in schema) are acceptable, so 4 is justified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description reinforces that the core parameter (query) is a 'description of the data or task' and mentions 'top-N' which maps to the limit parameter, but it adds little detail beyond what the schema already provides. The schema's aliases and examples carry most of the semantic weight.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb+resource: 'Find tools by describing the data or task.' It clearly distinguishes this meta-tool from sibling task-specific tools (e.g., search_books, compare_entities) by positioning itself as the discovery layer. The extensive list of domains (SEC filings, financials, FDA drugs, etc.) further clarifies scope.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly states when to use it: 'Use when you need to browse, search, look up, or discover what tools exist' and 'Call this FIRST when you have many tools available.' This gives clear context and priority guidance. However, it lacks an explicit 'when not to use' statement or named alternatives, so it stops short of a perfect 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.6/5.0
Disambiguation2/5

Multiple tool clusters are nearly indistinguishable: ask_pipeworx, ask_pipeworx_beta, and ask_pipeworx_grounded overlap heavily (beta is explicitly identical right now), and five polymarket tools (arbitrage, edges, edge_tracker, fill_risk, kalshi_spread) all concern prediction-market edge detection with fuzzy boundaries. entity_profile, recent_changes, and compare_entities also blur together for company research. Only the book tools are cleanly distinct, but they are drowned by the surrounding ambiguity.

Naming Consistency4/5

Most tools follow a consistent snake_case pattern and generally lead with a verb or clear noun (search_books, get_book, subscribe, unsubscribe, validate_claim, resolve_entity). A few depart from the verb-first convention (entity_profile, bet_research, pipeworx_trending, polymarket_edges) but the deviations are minor and do not hinder readability.

Tool Count2/5

35 tools is already heavy, but the critical problem is scope: the server is named gutendex (a book API) yet only 4 of 35 tools relate to books, with the other 31 forming an unrelated Pipeworx data/research/prediction-market suite. The count is inappropriate for the advertised purpose — it feels like two or three separate servers crammed into one.

Completeness2/5

For the gutendex domain, the book tools are thin: search, get, popular, and topic browsing exist, but common Gutendex capabilities like author browsing, language filtering, sorting, and pagination controls are missing. For the actual Pipeworx suite the surface is broad, but the server's stated purpose is gutendex, and the overwhelming majority of tools are completely off-topic, creating a severe coverage mismatch.
