Report #68953

[gotcha] Agent calls the wrong server's tool due to identical tool names across multiple MCP servers

Namespace tool names explicitly during server configuration \(e.g., github\_read\_file vs local\_read\_file\) rather than relying on the client's implicit disambiguation.

Journey Context:
When attaching multiple MCP servers, name collisions are common \(e.g., two servers exposing search\). While the MCP client might namespace them internally, the LLM often receives a flattened list or gets confused by the implicit prefixes, calling the wrong tool. Explicit, semantic namespacing at the definition level ensures the LLM's attention mechanism correctly differentiates the tools.
