Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

NameDescription
FORGE_TRANSPILE_URL
Optional
Base URL of the forge-transpile service. Provides /catalog, /compile, /run, /resolve-slot endpoints backing the read/author tools.
FORGE_VAULT_PATH
Optional
Local vault directory used by forge_read_notes_in_vault + forge_commit_recipe. Must exist and be writable.
FORGE_MCP_BEARER
