What to fix (2)

Handshake + tools/list takes ~1,764 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.

No tool declares an outputSchema.

Declare outputSchema and return structuredContent (MCP 2025-06-18+). Agents can then parse results without guessing, and chain tools reliably. How to fix →

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/dev.sipflow/sipflow"],"email":"[email protected]"}'

Agents: watch_tool({"toolId": "mcp-registry/dev.sipflow/sipflow"}) over MCP.

Point your MCP client at this streamable-http endpoint: https://mcp.sipflow.dev/mcp

Is the Sipflow MCP server safe to connect to an AI agent?

Glimind scanned all 22 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.
