Report #75469

[frontier] How do I route requests when multiple MCP servers expose similar tools?

Implement semantic routing—embed the query and tool descriptions, then route to the tool with highest cosine similarity to the query intent, dynamically selecting between shadowed tools.

Journey Context:
Hardcoded routing rules break when tools are added or when queries are ambiguous. Round-robin wastes specialized tools. Semantic routing treats tool selection as a similarity search, automatically matching query intent to tool capability descriptions. Tradeoff: adds embedding latency, but eliminates brittle if/else chains.
