Tool-selection accuracy drops as the menu grows, and some clients cap active tools.
1,799 of 15,360 reachable MCP servers (11.7%) have this issue today.
Clients such as Cursor limit how many tools are active at once, and models choose less accurately from very long lists. Group tools by task into toolsets, and merge near-duplicates behind one tool with a mode parameter.
Paste your endpoint at /check, or run it in CI:
pipx run glimind check https://your-server.example.com/mcp --min-grade B
