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).

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already mark this as readOnly, idempotent, and non-destructive, so the safety profile is covered. The description adds useful behavioral detail about the return payload: 'returns the top-N most relevant tools with names, descriptions, and full input schemas… each result is ready to call directly, no second schema lookup needed.' This goes beyond the structured annotations and is consistent with them.

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 three sentences are purposeful: the first states the action, the second enumerates relevant domains, and the third explains return format and usage timing. It is front-loaded with 'Find tools' and contains no filler. The domain list is somewhat long but each item is informative.

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?

Despite having no output schema, the description explicitly covers what the caller receives: top-N tool names, descriptions, full input schemas, and curated examples. It also provides the strategic context to invoke this tool first in a large toolset. It could mention relevance ordering or default limit, but the schema already documents limit, making the description adequate.

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?

All six parameters are documented in the input schema (100% coverage), so the description does not need to restate them. It adds no parameter-specific semantics beyond the general 'describing the data or task,' and the schema already provides aliases and examples. Baseline 3 is appropriate.

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 'Find tools by describing the data or task,' a specific verb+resource combination that clearly identifies this as a tool-discovery meta-command. It distinguishes from sibling research tools by emphasizing browsing/searching the available tool set rather than answering a single query. The enumerated domains (SEC filings, FDA drugs, economic data, etc.) further clarify 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?

It explicitly states when to use: 'Use when you need to browse, search, look up, or discover what tools exist' and advises 'Call this FIRST when you have many tools available.' It also gives a when-not cue with 'not just one answer,' but it does not name specific sibling tools as alternatives, so it falls just short of full marks.

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

A3.5/5.0
Disambiguation2/5

There are several clusters of tools with overlapping purposes: ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, and deep_research all route questions to data sources; entity_profile, compare_entities, and recent_changes all provide company research. The descriptions are detailed, but an agent could easily misselect among these near-duplicates, especially since ask_pipeworx_beta is explicitly identical to ask_pipeworx right now.

Naming Consistency2/5

Placeholder for naming consistency placeholder

Tool Count1/5

34 tools for a server named Newsapi is an extreme scope mismatch. Only three tools (everything, top_headlines, sources) are news-related; the rest cover data research, prediction markets, memory, subscriptions, and package scanning, which belongs in separate servers. The count is also past the 25+ range that feels overloaded for any single purpose.

Completeness3/5

The three NewsAPI tools themselves cover the standard news surface (top_headlines, everything, sources) with no major gaps. However, the server's stated purpose is diluted by ~30 unrelated tools, and the non-news tools form an incoherent assortment with no clear unified domain to assess completeness against. The mismatch makes completeness hard to reason about and degrades the overall usefulness.
