@compile/mcp

MCP server that compiles repeat LLM work out of the agent loop.

Install

Claude Code:

claude mcp add compile -- npx @compile/mcp

Cursor (cursor.json):

{ "mcpServers": { "compile": { "command": "npx", "args": ["@compile/mcp"] } } }

What it does

Plug Compile into an agent's traffic. It:

1. Logs every LLM call as a receipt (compile.observe_call).
2. Templates and clusters the receipts; scores each cluster on three axes (schema stability, determinism, economic value) and surfaces ranked codify candidates (compile.list_codify_candidates).
3. When the agent calls compile.find_function, returns a three-state lookup: positive (run the codified function), negative (uncodifiable — stay on the frontier model), or unknown (queue for synthesis).
4. For unknowns, the agent can call compile.request_synthesis to receive a synthesis spec and run codegen on its own LLM keys, then compile.submit_synthesis to validate and write to Vault.

The codegen never runs on Compile's API key. Customer prompts and traces never leave the customer's trust boundary.
