Check Dependencies

check_dependencies
Read-onlyIdempotent

Audit project dependencies (npm/PyPI/Maven/RubyGems/etc.) against CVE database: find known vulnerabilities in your package list. Bulk query up to 50 packages per call (same for Free and Pro). Use for dependency security scanning; use cve_lookup for single CVE. Free: 30/hr (1 per package), Pro: 500/hr. Returns {findings, total, by_severity, summary}. Each finding includes fixed_in (first release outside the matched vulnerable range: its exclusive upper bound from NVD, MITRE, GitHub advisory or OSV data, usually the first patched version) when a version range matched — omitted from wire when the range has no exclusive upper bound or no input version was supplied; remediation copy then says 'Check if ... is affected ... and upgrade if so' instead of 'Upgrade to X.Y.Z or later'.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
packagesYesList of dependency packages to audit. Each item is an object with 'name' (required, max 200 chars, e.g. 'lodash', 'django', 'log4j-core') and optional 'version' (max 100 chars, e.g. '4.17.0', '2.14.1'). Only 'name' and 'version' fields are used; extra fields are ignored. Example: [{"name": "lodash", "version": "4.17.0"}, {"name": "django"}]. Maximum 50 per request (same cap for Free and Pro).

A4.4/5.0
Behavior5/5

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

Annotations already declare readOnly/idempotent/non-destructive, and the description goes well beyond them: per-tier rate limits (Free 30/hr, Pro 500/hr), the 50-package batch cap for both tiers, the exact return shape, and the nuanced fixed_in omission semantics with the fallback remediation wording. That is substantial behavioral context not available in structured fields.

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?

Purpose and batching are front-loaded, and the rate limits and return shape are packed into short clauses. The final sentence explaining fixed_in and its omission case is long and clause-heavy, diluting an otherwise tight definition.

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?

With an output schema present, return values need not be described, yet the description still covers batch limits, tier-based throttling, an alternative sibling, and remediation edge cases. Nothing an agent needs to invoke it correctly appears to be missing.

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% and the single parameter is fully documented in the schema, including the 50-item cap and the name/version example. The description repeats the 50-package limit but adds no syntax or format detail beyond what the schema already provides, so the baseline 3 applies.

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 names a specific verb and resource ('Audit project dependencies against CVE database') and states the scope of the audit ('find known vulnerabilities in your package list'). It explicitly distinguishes itself from the sibling cve_lookup, so an agent can route without opening schemas.

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 states the use case ('dependency security scanning') and names one alternative ('use cve_lookup for single CVE'), giving a clear selection condition. It does not, however, mention the arguably closer sibling bulk_cve_lookup, which handles bulk CVE resolution, so the alternative routing is not exhaustive.

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