  • FORGE_VAULT_PATHLocal vault directory used by forge_read_notes_in_vault + forge_commit_recipe. Must exist and be writable.
  • FORGE_MCP_BEARERrequiredsecretBearer token forwarded to forge-transpile. Rotate by updating FORGE_TRANSPILE_SECRET on the upstream service and re-setting this. Dev fallback only when clients don't set Authorization on each request.
