Report #60707

[frontier] Orchestrator wastes tokens trying to pick which agent/tool to use via LLM routing

Use MCP capability negotiation to statically match requests to servers via capability manifests; compile a deterministic capability graph at startup and route via exact schema match, not LLM

Journey Context:
LLM-based routing is non-deterministic \(temperature > 0 causes different choices\), expensive \(burns 500\+ tokens per routing decision\), and hallucinates invalid tool names; MCP's capability negotiation allows compiling a capability graph at initialization—servers declare tools/schemas, clients declare requirements; build a trie or hash map for O\(1\) routing; only fall back to LLM on cache miss; eliminates routing token costs and guarantees deterministic behavior
