Overview

One local-subprocess MCP server’s configuration: a unique id (used by the LLM to call mcp_connect) and the argv array used to spawn the server process.

command is an argv array (not a shell string) to align with Subprocess.spawn conventions even though the mcp gem owns the actual spawn — see CLAUDE.md “Subprocess seam” carve-out. First element is the executable; remaining elements are arguments.

env carries extra environment variables for the spawned process —the stdio counterpart of HttpEntry‘s headers:, and the right place for a server’s auth token (e.g. {“GITHUB_TOKEN” => “…”}) rather than baking secrets into the argv. The mcp gem merges it over the inherited environment; an empty hash (the default) changes nothing. Like HttpEntry‘s headers, env is excluded from the cache fingerprint (Cache#transport_descriptor) so secrets never land on disk.
