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).

A4.1/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, and non-destructive. The description adds valuable behavioral detail: it returns top-N tools with names, descriptions, and full schemas, and is ready to call directly without a second schema lookup. This describes output format and efficiency without contradicting 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 well-structured and front-loaded with purpose. The list of data domains is long but informative, showing the scope of discoverable topics. Every sentence contributes; the trade-off between length and utility is acceptable.

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?

With no output schema, the description compensates by explaining return contents and direct-callability. It covers what it returns (names, descriptions, schemas), the limit behavior, and mentions curated examples. Combined with annotations for safety, this is fairly complete for a discovery tool.

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 coverage is 100%, so baseline is 3. The description mentions 'top-N' which hints at the limit parameter, but the query semantics are already fully described in the schema (natural language description, aliases). No additional parameter meaning is added beyond the schema.

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 starts with a specific verb+resource pairing: 'Find tools by describing the data or task.' It clearly distinguishes itself from siblings by positioning as a meta-tool for discovery ('Call this FIRST when you have many tools available'), not as a direct data/research tool like deep_research or search_packages.

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?

Explicit usage context is provided: 'Use when you need to browse, search, look up, or discover what tools exist' and 'Call this FIRST... not just one answer.' This gives clear when-to-use, though it does not explicitly name alternative tools or state when not to use it beyond the 'not just one answer' qualifier.

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
Disambiguation4/5

Descriptions are exceptionally detailed and differentiate tools well; the ask_pipeworx family (stable/beta/grounded), polymarket tools, and npm lookup tools each have clear separation of intent. Minor overlap exists between polymarket_edges and polymarket_arbitrage (both surface opportunities) and between discover_tools, suggest_questions, and pipeworx_trending (all aid discovery), but descriptions mostly resolve the ambiguity.

Naming Consistency3/5

All names are snake_case and several families are consistent (get_*, list_*, search_*, ask_pipeworx, polymarket_*), but the convention is inconsistent: verb-first names (resolve_entity, validate_claim, scan_dependency) coexist with noun-first or noun-only names (entity_profile, deep_research, bet_research, recent_alerts, ai_visibility_check, pipeworx_trending, polymarket_arbitrage). No clear governing pattern beyond snake_case.

Tool Count2/5

36 tools is well over the 25-tool heavy threshold, and the majority (~29) are unrelated to the server's declared 'npm' identity — they are Pipeworx data-query, prediction-market, memory, and subscription tools. Only about 7 tools (search_packages, get_package, get_version_info, list_versions, get_downloads, scan_dependency, generate_llms_txt) actually pertain to npm. The scope is a kitchen-sink mismatch with the server name.

Completeness3/5

For npm, the read-side surface is reasonably complete: search, inspect package metadata, version listings, download counts, and a dependency-safety composite check. However, there are no lifecycle operations (publish, unpublish, deprecate, set versions/tags), leaving a notable gap, and the bulk of the server's functionality (data queries, prediction bets) belongs to an entirely different domain that can't be cohesively evaluated against the npm purpose.
