MCP Trust Report: GitHub Leads, Filesystem Needs Scoping

GitHub MCP Server leads this week because it combines first-party provenance, broad developer usefulness, and reviewable permission boundaries. The larger signal: teams should treat MCP installation as a security decision, not a directory browse.

Why this matters

First-party publisher and clear repository/package provenance.

High-value developer workflows across repository search, issue triage, and pull-request review.

Permission risk is manageable when teams pin repository scopes and separate read-only from write-capable actions.

Watch list

Filesystem remains essential but depends on strict path scoping.

Context7 is a strong low-risk documentation candidate for coding teams.

Slack and Stripe are high-utility but high-risk until OAuth scopes and mutation controls are verified.

Biggest risk note

High-utility servers increasingly touch sensitive systems: payments, chat history, local files, databases, and browser sessions. MCP Rank will not include those servers in safest lists unless confidence is medium/high and the risk surface is explicit.

What changed

Expanded the indexed dataset beyond 50 public MCP servers.

Promoted GitHub, Filesystem, and Context7 to high-confidence deep reviews.

Separated indexed listings from trusted rankings so unreviewed tools do not inflate leaderboard trust.
