README Excerpt

A semantic proxy for MCP servers. Solves **tool selection degradation** — when an LLM has too many tools, it picks the wrong ones. The sieve sits between the client (Claude Code, Hermes, any MCP client) and downstream MCP servers. The client sees **2 tools** instead of dozens: `mcp_router_select` + `mcp_router_call`. The first finds relevant tools via embeddings, the second proxies the call.
