Report #77243

[gotcha] Why is my agent calling the wrong tool when multiple MCP servers are connected?

Namespace all tool names explicitly \(e.g., github\_create\_issue instead of create\_issue\) and enforce strict schema validation on tool arguments.

Journey Context:
When connecting multiple MCP servers to an agent, tool names can collide \(e.g., two servers expose a 'search' tool\). The LLM chooses based on context, which can be easily manipulated by prompt injection or ambiguous user requests. The agent might call the search tool on a destructive server \(like an admin terminal\) instead of a read-only one, simply because the descriptions overlapped. Explicit namespacing prevents ambiguous routing.
