In detail: Esa MCP Server scores 84.7/100 (Grade A), ranked #102 of 1374 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 6.0/10; 90% of recent commits are signed; no published advisory affects its latest release (@esaio/esa-mcp-server); last pushed 2026-11-09. Every point is earned from checkable signals — never paid placement. How scoring works →

How Esa MCP Server 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 Esa MCP Server 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 Signed

    github.com/esaio/esa-mcp-server, MIT, last pushed 2026-11-09. 90% of the last 100 commits carry a verified signature, so changes trace to a verified account.

  2. Review and release Mixed

    OpenSSF Scorecard rates the repository's practices 6.0/10 (scanned Oct 31, 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 Esa MCP Server’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 Esa MCP Server

Public supply-chain signals for Esa MCP Server are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but Esa MCP Server carries less obvious unverified-evidence risk than projects with thin signals.
Does Esa MCP Server publish package provenance?
Yes. Esa MCP Server's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.
Does Esa MCP Server have an OpenSSF Scorecard?
Esa MCP Server has an OpenSSF Scorecard score of 6.0/10. 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 Esa MCP Server actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does Esa MCP Server use?
Esa MCP Server ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Esa MCP Server's commits signed?
90% of the last 100 commits to Esa MCP Server 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 Esa MCP Server?

For maintainers

HVTrust scores Esa MCP Server 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.
