What to fix (2)

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 →

3 parameter(s) across 2 tool(s) have no description.

Add a "description" to each parameter with its format and an example ("ISO 8601 date, e.g. 2026-10-17"). This is the commonest cause of wrong arguments on the first call. How to fix →

Is the Lulu The Narwhal Weather MCP server safe to connect to an AI agent?

Glimind scanned all 2 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.
