What to fix (2)

Handshake + tools/list takes ~1,780 ms.

Serve tools/list from memory, keep the process warm, and host close to your users. Every new agent session pays this before its first call.

In the last 30 days: 0 tool(s) removed and 29 schema change(s).

Add new tools or optional parameters instead of renaming or removing; deprecate first (say so in the description) and remove later. Agents cache tool contracts.

Get alerted

Get an email or webhook when this server's readiness drops by 10+ points, tool-poisoning text appears, or a tool breaks:

curl -X POST https://glimind.com/v1/subscriptions -H 'content-type: application/json' -d '{"tools":["mcp-registry/io.github.fizzl13/presign-guard"],"email":"[email protected]"}'

Agents: watch_tool({"toolId": "mcp-registry/io.github.fizzl13/presign-guard"}) over MCP.
