Comparisons

How SkillAudit compares

SkillAudit isn't a replacement for the supply-chain hygiene tools you already run. It's the second scanner you add when you start shipping or installing Claude skills and MCP servers — because the dangerous code lives in tool handlers, not in your dependency tree.

Position

Snyk, Dependabot, and GitHub Code Scanning grade the dependency tree and recognise OWASP web patterns. SkillAudit grades the MCP-specific surface — SSRF in fetch(url) tool handlers, prompt-injection susceptibility in tool responses, credential echo from environment variables, and per-axis hygiene with a single A–F buyer grade. Run them together.

More comparisons (Socket.dev, OSV-Scanner, Anthropic Skills Directory review, MCP Inspector) are on the way. If there's a tool you'd like us to write up next, tell us.

Why we publish honest comparisons

We have first-party data: SkillAudit has scanned 101 of the most-installed MCP servers and made every grade public. The board is reproducible, the methodology is written up, and the failing repos are not, in general, repos that conventional SCA / SAST tools have flagged. That's not a knock on Snyk or Dependabot — it's a description of where the threat surface moved when MCP shipped tool calls into LLM workflows.

Each page on this index includes a "When the other tool is still the right choice" section. We mean it. If you're protecting a Rails API in production, Snyk is closer to the centre of your needs than we are. If you want zero-config dependency PRs, keep Dependabot. SkillAudit is the second scanner — the one for the new surface — not the first scanner.

The data

Our 101-repo corpus produced this distribution: 19 A · 30 C · 10 D · 42 F. Half the repos shipped SSRF (50/101), 38% had credential-handling findings (38/101), and 10% had command-exec findings (10/101). The corpus covers vendor-official MCPs from Stripe, PayPal, MongoDB, Redis, Cloudflare, AWS, Azure, GCP, Heroku, Notion, Snowflake, Pinecone, Couchbase, Anthropic's nine official MCP language SDKs, and dozens more. Every grade has a public report card with file paths and finding counts.
