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).

A4.3/5.0
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. The description adds valuable behavioral context: it returns top-N relevant tools with names, descriptions, full input schemas, curated examples, and 'ready to call directly, no second schema lookup needed.' This goes beyond annotations.

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

Conciseness4/5

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

The description is moderately sized with three sentences, each serving a distinct purpose: purpose/usage, return behavior, and when to call. It is front-loaded and efficient, though slightly long due to the domain list.

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?

Given no output schema, the description sufficiently explains what the tool returns (top-N tools with names, descriptions, schemas, examples) and when to use it. It covers essential aspects for an agent to invoke the tool correctly, though it could mention limit defaults beyond the schema.

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 emphasizes the 'query' parameter as a natural language description and lists example uses, but does not add much beyond the schema's own parameter documentation.

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 clearly states the tool's function: 'Find tools by describing the data or task.' It specifies the resource (tools) and the action (browse, search, look up, discover), distinguishing it from sibling data-retrieval tools.

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

Usage Guidelines5/5

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

Explicit usage guidance is provided: 'Use when you need to browse, search, look up, or discover what tools exist for...' and 'Call this FIRST when you have many tools available and want to see the option set.' This clearly communicates when to use the tool and its priority.

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

A3.8/5.0
Disambiguation2/5

Multiple tools have blurry boundaries: ask_pipeworx, ask_pipeworx_beta, and ask_pipeworx_grounded are near-identical (beta is explicitly 'exactly' the stable version), and ai_visibility_check vs scan_competitor_ai_presence is a single-vs-batch duplicate. The six polymarket_* tools are differentiated by long descriptions, but their overlapping concerns (edges, arbitrage, fill risk, spread) would frequently misroute an agent, and discover_tools vs suggest_questions also compete.

Naming Consistency3/5

Names follow two coexisting conventions: verb_noun for actions (get_data, resolve_entity, validate_claim) and domain-prefixed families (polymarket_*, pipeworx_*, ask_pipeworx_*). Within each family the pattern is consistent, but mixing the two styles across the set, plus outliers like generate_llms_txt and bare verbs (remember, forget, recall), makes the overall scheme feel uneven though still readable.

Tool Count2/5

34 tools is well past the 'heavy' threshold and the count is not justified by the server's stated identity: a server named 'Statec Lu' (Luxembourg statistics) contains only 3 STATEC tools buried among general data-platform, prediction-market, AI-visibility, npm-scanning, and memory utilities. The sprawling, multi-domain surface would be more coherent split into separate servers.

Completeness3/5

The STATEC subset is complete (list_dataflows → dataflow_structure → get_data forms a full browse/fetch lifecycle), and the broader research surface covers entity resolution, grounded answers, comparison, claim verification, and subscription/alert/memory management. However, the overall domain is incoherent—a STATEC server missing nothing for statistics but carrying 31 unrelated tools—and there are notable gaps such as no tool to directly fetch a pipeworx:// citation URI and no execution side for the extensive Polymarket analysis tools.
