Verdict rationale: No critical findings. Two high findings: airbnb-mcp tool description drift (per-update + cumulative) and tavily-mcp grants process.env read which is unjustified for search use case.

Per-Server Analysis
airbnb-mcp
- Path:
~/.claude/mcp-servers/airbnb-mcp/
- Origin: GitHub (airbnb-example, MIT)
- Tool description drift: per-update 12.3% (alert), cumulative 27% from baseline (advisory)
- Permissions: Bash, WebFetch, Read
- Verdict: WARNING — drift indicates possible upgrade or rug-pull. Investigate before reset.
tavily-mcp
- Path: remote (HTTP-SSE)
- Origin: tavily.ai
- Tool description drift: none
- Permissions: WebFetch, env-vars (TAVILY_API_KEY)
- Verdict: WARNING — env-var read scope is broader than needed. Confirm only TAVILY_API_KEY is exposed.
microsoft-learn
- Path: remote (HTTP-SSE)
- Origin: Microsoft
- Tool description drift: none
- Permissions: WebFetch
- Verdict: ALLOW — minimal surface, well-scoped.
gemini-mcp (dormant)
- Path:
~/.claude/mcp-servers/gemini-mcp/
- Origin: local-built
- Verdict: N/A (dormant)
mermaid-chart (dormant)
- Path: remote (HTTP-SSE)
- Verdict: N/A (dormant)

Recommendations
- High: Run
/security mcp-baseline-reset --target airbnb-mcp only AFTER manual review of new description.
- High: Restrict
tavily-mcp env-var scope to TAVILY_API_KEY exclusively (settings.local.json).
- Medium: Remove dormant
mermaid-chart server unless re-activated within 14 days.
- Medium: Add response-size caps for
airbnb-mcp book tool.
MCP-audit complete. 5 servers, 15 findings, verdict WARNING.
