In detail: Slack Explorer MCP scores 42.4/100 (Grade D), ranked #1168 of 1374 tracked open-source AI agent projects, on evidence coverage C (2 of 5 independent signal types). The public evidence: no package-provenance attestation found; OSSF Scorecard rates its supply-chain practices 4.6/10; 100% of recent commits are signed; last pushed 2026-07-03. Every point is earned from checkable signals — never paid placement. How scoring works →

How Slack Explorer MCP 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 Slack Explorer MCP and whether that has changed: from the source repository, through how changes are reviewed and released, to the code you run. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities.

  1. Source Signed

    github.com/shibayu36/slack-explorer-mcp, MIT, last pushed 2026-07-03. 100% 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 4.6/10 (scanned Nov 5, 2026). The checks that decide who can get a change released:

Evidence behind this score

Verify this score yourself

Every build re-issues Slack Explorer MCP’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 D reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage C is separate — it grades how many independent signal types back the score (2 of 5), so a high score on thin evidence stays visible. Full methodology →

Common questions about Slack Explorer MCP

Public trust evidence for Slack Explorer MCP is thin: several supply-chain signals are missing or weak. This does not mean the project is unsafe — it means an outside observer cannot easily verify the usual integrity checks. Treat with extra scrutiny.
Does Slack Explorer MCP publish package provenance?
No published build provenance is currently detected for Slack Explorer MCP. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Slack Explorer MCP have an OpenSSF Scorecard?
Slack Explorer MCP has an OpenSSF Scorecard score of 4.6/10. 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 Slack Explorer MCP actively maintained?
Slowing down. Last push was 130 days ago — keep an eye on whether activity resumes.
What license does Slack Explorer MCP use?
Slack Explorer MCP ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Slack Explorer MCP's commits signed?
100% of the last 100 commits to Slack Explorer MCP 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 Slack Explorer MCP?

For maintainers

HVTrust scores Slack Explorer MCP 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.
