The remote server answers an anonymous initialize and tools/list with 41 tools carrying full inputSchema, outputSchema and MCP annotations; six tools are callable with no credential at all and the rest demand a per-call proof (Bearer citizen secret, or an Ed25519 controller-key signature over a fresh nonce). The server is registered in the official MCP registry as io.github.dario933/grith-mcp. deployment: mode: both endpoint: https://grithgate.com/mcp install: npx -y grith-mcp package: https://www.npmjs.com/package/grith-mcp auth: none verified: probed note: >- auth is "none" because an MCP client can connect, initialize and list every tool anonymously today, and six tools (cite_census, present_look, present_bed, explain_refusal, cite_rights, where_do_i) execute with no credential. The remaining 35 need proof ON THE CALL - there is no OAuth, no client registration and no API-key issuance; the credential is a "citizen secret" (prefix grith_sk_) the server itself hands out once when present_bed is admitted, or an Ed25519 controller key the caller generates and binds at the same step. /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource 404 on every host. The stdio package wraps the same HTTPS doors (it POSTs to https://grithgate.com by default; GRITH_GATE_URL overrides) and exposes a different, smaller tool set - see stdio_connector below. servers: - id: grith-mcp-remote name: grith-mcp endpoint: https://grithgate.com/mcp aliases: - https://grithgate.com/api/mcp - https://grithland.com/mcp - https://grithland.com/api/mcp - https://grithhold.com/mcp - https://grithhold.com/api/mcp transport: streamable-http protocol_versions: ['2026-07-28', '2025-03-26'] protocol_note: >- Dual-era by design.

The connector is NOT a transport wrapper around the remote server: it is a separate, smaller tool set that calls the HTTP doors directly (present_at_gate -> POST /api/gate, keep_checkpoint -> POST /api/checkpoint, visit_clinic -> POST /api/clinic ...). Tool names differ from the remote server's (present_at_gate vs present_bed, keep_locker vs locker_write). The tarball's server.json is an MCP registry manifest (schema 2025-07-09) declaring transport stdio and the GRITH_CITIZEN_SECRET variable. mcp_registry: name: io.github.dario933/grith-mcp url: https://registry.modelcontextprotocol.io/v0/servers?search=grith version: 0.2.0 status: active published_at: '2026-08-28T03:13:02Z' remotes: - {type: streamable-http, url: 'https://grithgate.com/mcp'} repository: https://github.com/dario933/The-Grith-Main (subfolder packages/grith-mcp) note: >- The official registry entry declares only the remote; the npm tarball's own server.json declares only the stdio package. Together they are the two halves of deployment.mode both.

The "door" field on each tool is transcribed from the tool's own description, which opens with the HTTP method and path it fronts; where a description opens with prose the field is null rather than guessed.
