Questions

Which cyanheads MCP server has the best trust score?
Filesystem (cyanheads/filesystem-mcp-server) and Mentor (cyanheads/mentor-mcp-server), ranked by trust score and then stars.
Are cyanheads's MCP servers read-only?
7 of 16 declare only read tools; 2 expose at least one destructive tool; 4 build their tool list at runtime, so we cannot read it from the source.
