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 Security98
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • No install/post-install scripts declared.Pass
  • 31 of 96 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability79
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 370 tokens (~123/item across 3 items; 3 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management97
  • Stability observed for 29 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the io.github.attestd-io/attestd-mcp server?

io.github.attestd-io/attestd-mcp runs locally as an npm package, launched with npx -y @attestd/mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 3 exposed · ~370 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 →

Tool Tokens
check_batch_vulnerabilities ~131

Check up to 100 software packages or infrastructure products in a single request. Each item is billed as one API call. Use this instead of multiple check_package_vulnerability calls when you need to audit a lockfile, manifest, or dependency list. Items outside Attestd coverage return outsideCoverage=true and should be treated as unknown risk, not safe. A 429 is returned before any results are delivered if the batch would exceed your monthly quota; no calls are billed in that case.

itemsarrayyesProducts to check. Maximum 100 per call. Each item costs one API call.

No examples provided.

check_package_vulnerability ~164

Check whether a software package or infrastructure product version has known CVE vulnerabilities or a confirmed supply chain compromise. Call this before adding, updating, or recommending any npm, PyPI, or infrastructure dependency, including mid-conversation when a developer asks about installing or upgrading a package. outsideCoverage=true means Attestd has no data for that product; treat as unknown risk, not safe. Covers infrastructure products (nginx, PostgreSQL, Redis, Docker, Kubernetes, etc.) and PyPI/npm packages.

NameTypeReqDescription

No examples provided.

list_covered_products ~75

Returns infrastructure product slugs covered by Attestd for CVE checks. PyPI and npm packages also work with check_package_vulnerability even when absent from this list. Call this first if you are unsure whether an infrastructure slug is supported. Uses a static bundled list. No /v1/check API call for this tool.

Input schema present but exposes no named parameters.
