C Why this grade 100 − 24.1 = 76/100

Every server starts at 100. These are the exact deductions the deterministic engine applied — each one reproducible, none of it an opinion or an LLM's guess:

PointsWhat was foundCategory
−22 Hardcoded Slack token in server code MTC-SRC-008 exfiltration
−2.1 Package has no source repository MTC-SUP-011 supply-chain

Grade capped: 1 confirmed high finding → grade capped at C. A hard gate overrides the point total — no amount of clean surface buys back a confirmed catastrophe.

Capability observations and info notes are shown under Findings but never scored. Open any row's finding below for the file, line and evidence behind the deduction.

Findings 2

high Hardcoded Slack token in server code (build/index.js)MTC-SRC-008

A live-looking Slack token is hardcoded in `build/index.js:21`. Secrets in source ship to everyone who installs the package and are a direct credential leak.

Evidence: Slack token: xoxb…(redacted)

Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.

Location: server build/index.js

low Package has no source repositoryMTC-SUP-011

"slack-workspace-mcp-server" declares no repository URL, so its published artifact cannot be compared against reviewable source.

Fix: Prefer packages that link to public, reviewable source.

Location: package slack-workspace-mcp-server

Versions

Scan history per published version. The engine is deterministic — the same version always yields the same score, so a changed score means the package itself changed.

Embed this score

Show this server's live Trust Score in your README, docs or website. The badge is served straight from the registry and updates automatically after every rescan — no API key needed. It links back to this page, so anyone who sees the grade can also read the findings behind it instead of taking a number on faith.
