Scan Dependency

scan_dependency
Read-onlyIdempotent

Composite "should I add this npm package to my project" check in ONE call — fans out across deps.dev (license + advisories + version history) and bundlephobia (gzipped/minified bundle size, dependency count, ESM/tree-shake support). Use whenever an agent asks "is X safe / popular / small" or "what does adding lodash cost me". Returns a summary block (is_latest, license, published_at, advisory_count, bundle_kb_min, bundle_kb_gz, dependency_count, has_esm, tree_shakeable), per-advisory detail, links, and a list of recent alternative versions. NPM ecosystem only in v1; PyPI / Maven / Cargo / Go fall under deps.dev:version directly. Partial failures degrade gracefully — bundlephobia's first measurement on a new version can take 5-30s; sources_failed will list it if it times out, the rest still returns.

A4.8/5.0
Behavior5/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint false. Description adds valuable behavioral context: composite call fans out, partial failures degrade gracefully, bundlephobia first measurement may take 5-30s and will be listed in sources_failed if timed out.

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?

Description is detailed but every sentence adds specific information: purpose, usage, return structure, ecosystem limitation, failure behavior. Could be slightly more concise but is well-structured and informative.

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

Completeness5/5

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

Despite no output schema, description lists all return fields (summary block fields: is_latest, license, published_at, etc.), per-advisory detail, links, alternative versions. Covers inputs, behavior, and outputs completely for a two-parameter tool.

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

Parameters4/5

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

Schema covers both parameters with descriptions (100% coverage). Description adds that scoped packages are accepted and version defaults to latest, providing minor extra value beyond 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?

Description clearly states the composite purpose: 'should I add this npm package to my project' check aggregating deps.dev and bundlephobia data. It distinguishes itself from siblings by being the only dependency scanning tool.

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: 'Use whenever an agent asks "is X safe / popular / small" or "what does adding lodash cost me"'. Also notes ecosystem limitation and alternatives: 'NPM ecosystem only in v1; PyPI / Maven / Cargo / Go fall under deps.dev:version directly'.

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

Multiple tools have heavily overlapping purposes: ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, and deep_research all handle query routing, and the five polymarket_* tools plus bet_research blur the line between market scanning, edge detection, and fill-risk analysis. Several pairs (entity_profile/compare_entities/recent_changes, ai_visibility_check/scan_competitor_ai_presence) also overlap substantially.

Naming Consistency2/5

The tool names mix multiple conventions: verb_noun (validate_gtin, list_subscriptions, generate_llms_txt), brand-prefixed groups (pipeworx_*, polymarket_*, ask_pipeworx*), and bare nouns (entity_profile, recent_alerts). The server is named after GTIN/barcodes, yet most tools are branded Pipeworx or Polymarket, making the set feel incoherently named.

Tool Count2/5

33 tools is well over the threshold where a typical agent can comfortably navigate the surface, especially since they span unrelated domains: barcode validation, data lookups, prediction-market arbitrage, memory storage, subscriptions, npm scanning, and llms.txt generation. The count reflects an overgrown grab bag rather than a well-scoped toolset.

Completeness2/5

There is no coherent domain to assess completeness against: for the server's apparent GTIN/barcode purpose, only gtin_check_digit and validate_gtin exist (and not even a lookup for product data by GTIN). For the broader Pipeworx platform hinted at by most tools, the surface is scattered, with deep coverage of prediction-market edges but arbitrary one-off utilities elsewhere.
