Trust breakdown (7 categories)

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. How we score → Why this is hard to score →

Supply Chain Security94
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • Runs a script at install time (build_backend) that we could not recognise. It may be perfectly ordinary, but we do not read the published tarball, so we cannot say what it does. View diagnostics → Partial
  • 1 of 19 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency48
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
  • Clear OSI-approved license (MIT).Pass
  • Actively maintained (last published 20 days ago).Pass
  • Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability85
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 497 tokens (~49/item across 10 items; 8 tools + 2 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management57
  • Stability observed for 17 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a current MCP spec version (2026-07-28).Pass

MCP tools · 8 exposed · ~468 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the io.github.Anselmoo/mcp-server-analyzer server?

io.github.Anselmoo/mcp-server-analyzer is listed in the public MCP registry as io.github.Anselmoo/mcp-server-analyzer. MCP server for Python, JavaScript, and TypeScript code analysis with Ruff, ty, Vulture, and Biome. This page covers its PyPI package (mcp-server-analyzer).

Is the io.github.Anselmoo/mcp-server-analyzer server safe to use?

io.github.Anselmoo/mcp-server-analyzer scores 79 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. 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 io.github.Anselmoo/mcp-server-analyzer server expose?

io.github.Anselmoo/mcp-server-analyzer exposes 8 tools: ruff-check, ruff-format, ruff-check-ci, ty-check, vulture-scan, and 3 more. Their descriptions and schemas cost roughly 468 tokens of context every time the server is loaded.

Is the io.github.Anselmoo/mcp-server-analyzer server still maintained?

io.github.Anselmoo/mcp-server-analyzer is still listed as active in the MCP registry. We last reached this channel on 20 September 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 io.github.Anselmoo/mcp-server-analyzer server under?

io.github.Anselmoo/mcp-server-analyzer declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
