On the wire — recorded from a real request

Symptom

what you'll observe

Two tools share a name; the client calls one but gets the other's behaviour.

Cause

what this reproduces

Name collision from merging tool sets or a templating bug.

Fix

how you'd resolve it

Enforce unique tool names at registration; namespace them if merging sources.

Try it with curl

bash

curl -sS -X POST \
  https://chaos-mcp.thomascdnns.com/s/duplicate-tool-names/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -d '{

      "protocolVersion": "2024-11-05",
      "capabilities": {},
      "clientInfo": {"name": "curl", "version": "1"}
    }
  }'
