In detail: FastMCP (TypeScript) scores 86.8/100 (Grade A), ranked #65 of 1371 tracked open-source AI agent projects, on evidence coverage B (3 of 5 independent signal types). The public evidence: its packages ship with cryptographic provenance; OSSF Scorecard rates its supply-chain practices 4.5/10; 79% of recent commits are signed; no published advisory affects its latest release (fastmcp); last pushed 2026-10-04. Every point is earned from checkable signals — never paid placement. How scoring works →

How FastMCP (TypeScript) could raise its score

Each line changes one public signal and recomputes with the live scoring function. The gains don't add up exactly, because the score is capped near the top.

Chain of custody

Scanners check what the code says. This traces who ships FastMCP (TypeScript) and whether that has changed: from the source repository, through how changes are reviewed and released, to the package you install. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities.

  1. Source Partly signed

    github.com/punkpeye/fastmcp, MIT, last pushed 2026-10-04. 79% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.

  2. Review and release Mixed

    OpenSSF Scorecard rates the repository's practices 4.5/10 (scanned Oct 9, 2026). The checks that decide who can get a change released:

Evidence behind this score

Coverage B: 3 of 5 independent evidence types found.

  • GitHub repository data
  • Package downloads
  • Supply-chain checks
  • Public actions (missing)
  • Community mentions (missing)

Verify this score yourself

Every build re-issues FastMCP (TypeScript)’s score as an Ed25519-signed credential, valid for 7 days. You can check it offline against HVTracker’s published key; if anyone changes a number after signing, verification fails.

What this score doesn’t check

It covers who ships the code, not what the code does. It doesn’t read tool descriptions or prompts for injected instructions, watch runtime behaviour, or find bugs nobody has disclosed yet. For that, run a content scanner before you connect it, such as Cisco MCP Scanner or Snyk Agent Scan.

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade A reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage B is separate — it grades how many independent signal types back the score (3 of 5), so a high score on thin evidence stays visible. Full methodology →

Common questions about FastMCP (TypeScript)

Public supply-chain signals for FastMCP (TypeScript) are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but FastMCP (TypeScript) carries less obvious unverified-evidence risk than projects with thin signals.
Does FastMCP (TypeScript) publish package provenance?
Yes. FastMCP (TypeScript)'s package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.
Does FastMCP (TypeScript) have an OpenSSF Scorecard?
FastMCP (TypeScript) has an OpenSSF Scorecard score of 4.5/10. The Scorecard checks for branch protection, signed releases, dependency updates, fuzzing, code review, and other supply-chain hygiene items. See the full check breakdown on this page.
Is FastMCP (TypeScript) actively maintained?
Maintained. Last push was 9 days ago.
What license does FastMCP (TypeScript) use?
FastMCP (TypeScript) ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are FastMCP (TypeScript)'s commits signed?
79% of the last 100 commits to FastMCP (TypeScript) are verified-signed (GPG, SSH, S/MIME, or GitHub's signing flow). Signed commits help confirm that code was authored by who the commit claims.

Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.

Maintain FastMCP (TypeScript)?

For maintainers

HVTrust scores FastMCP (TypeScript) from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
