## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 19/100
  - Repository check failed: no source repository is declared.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 1 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 58/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 415 tokens (~207/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 83/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 50% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (2)

### `scan_dependencies` (~260 tokens)

Scan a dependency manifest for vulnerable and malicious packages

Checks a package.json, lockfile, requirements.txt, go.mod, Cargo.lock, poetry.lock or composer.lock (contents or a local path) or a package list against OSV.dev for known vulnerabilities and confirmed-malicious packages. Free preview by default (verdict and counts, up to 25 packages). With PKGGUARD_X402_PRIVATE_KEY set, returns the full paid result (affected packages, advisory ids, severity, CVSS, fixed-in versions; up to 500 packages) from https://api.youraitools.co/pkgguard/v1/scan, paying $0.003 USDC on Base per scan over x402. Informational: lists published advisories from OSV.dev for the versions given. Not a security audit; a clean result does not prove a package is safe.

Input parameters:

- `filename` (string)
- `include_dev` (boolean)
- `manifest` (string): File contents (package.json, package-lock.json, requirements.txt, Pipfile.lock, poetry.lock, go.mod, Cargo.lock, composer.lock)
- `packages` (array): [{ecosystem, name, version}]
- `path` (string): Or a local file path to read (e.g. ./package-lock.json)

### `check_package` (~92 tokens)

Is this package version vulnerable or malicious?

Checks one package version (npm, PyPI, Go, crates.io, Packagist, RubyGems, Maven, NuGet, Pub, Hex) against OSV.dev. Paid mode uses https://api.youraitools.co/pkgguard/v1/package ($0.001).

Input parameters:

- `ecosystem` (string): default npm
- `name` (string, required)
- `version` (string, required)

### Is the PkgGuard MCP server safe to use?

PkgGuard scores 61 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 23 October 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the PkgGuard MCP server expose?

PkgGuard exposes 2 tools: scan_dependencies, check_package. Their descriptions and schemas cost roughly 352 tokens of context every time the server is loaded.

### Is the PkgGuard MCP server still maintained?

PkgGuard is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the PkgGuard MCP server under?

PkgGuard declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
