What to fix (3)

The endpoint did not complete an MCP handshake.

Check the URL, TLS certificate and that the server answers a JSON-RPC "initialize" POST. How to fix →

Reachable 93.3% of the time over the last 30 days; median recovery 1552 min.

Agents fail over to an alternative the first time a call fails. Add health checks and restart-on-failure, and avoid cold starts on serverless hosts.

1 tool(s) look like they change state (create/send/delete/pay…) but declare no destructiveHint.

Set annotations {"readOnlyHint": false, "destructiveHint": true|false, "idempotentHint": …}. Clients use these to ask the user before a side effect and to auto-approve safe reads. How to fix →

Is the Benroberts B4 Index MCP server safe to connect to an AI agent?

Glimind scanned all 5 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.
