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 2026-09-20. - **Supply Chain Security**: 0/100 - Malware scan not yet available for this package. - Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it. - Install-script risk not yet assessed. - Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it. - **Provenance & Transparency**: 48/100 - Source repository is publicly reachable at the declared URL. - Provenance check failed: no build-provenance attestation is published. - Clear OSI-approved license (MIT). - Actively maintained (last published 20 days ago). - Publishes a security disclosure policy (SECURITY.md). - **Schema Quality & AI Usability**: 85/100 - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name). - AI-judged instruction clarity (good). - Tool/resource definitions use about 497 tokens (~49/item across 10 items; 8 tools + 2 resources), lean. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 57/100 - Stability observed for 17 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 100/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 100% of tool parameters carry a description. - Structured output schemas are declared (100% of tools); any adoption earns full credit. - **Tool Safety**: 100/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation. - An AI judge read all 9 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. **Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm. ## Install ### How do I install the io.github.Anselmoo/mcp-server-analyzer server? io.github.Anselmoo/mcp-server-analyzer runs locally as a container image, launched with docker run --rm -i ghcr.io/anselmoo/mcp-server-analyzer:0.4.1.

MCP server for Python, JavaScript, and TypeScript code analysis with Ruff, ty, Vulture, and Biome. This page covers its container image (ghcr.io/anselmoo/mcp-server-analyzer:0.4.1). ### Is the io.github.Anselmoo/mcp-server-analyzer server safe to use? io.github.Anselmoo/mcp-server-analyzer scores 51 out of 100 on VerifyMCP. 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. ## Links - Repository: https://github.com/Anselmoo/mcp-server-analyzer - Changelog RSS feed: https://verifymcp.io/servers/anselmoo-mcp-server-analyzer/ghcr-io-anselmoo-mcp-server-analyzer-0-4-1.xml - Changelog JSON feed: https://verifymcp.io/servers/anselmoo-mcp-server-analyzer/ghcr-io-anselmoo-mcp-server-analyzer-0-4-1.json - HTML version of this page: https://verifymcp.io/servers/anselmoo-mcp-server-analyzer/ghcr-io-anselmoo-mcp-server-analyzer-0-4-1
