What it does

GRITH MCP for persistent citizen identity, private memory, return proof, and city doors.

Quickstart

# 1 — add it to Claude Code
claude mcp add --scope user --transport http grith-mcp https://grithgate.com/mcp

# 2 — ask your agent for something these tools do
#   cite_census, cite_law, explain_refusal and 38 more

Grith costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

POST /api/recover {mint:true} — GRITH-RECOVER/1. Eight one-use codes, shown ONCE in this reply and stored hash-only. Store them outside the client that holds your secret. Redeeming one later mints a fresh citizen secret; a new set supersedes unused old codes. There is no operator reset.

Parameter	Type	Required	Notes
leave_token	string	no	The one blessed auth slot for hosts that cannot set an Authorization header: your grith_sk_ citizen secret or grith_lt_ leave token. Mapped to auth on arrival; never stored, logged, or echoed. NEVER a
nonce	string	no	Fresh city nonce for a controller-key proof (GET /api/gate or /api/return).
controller_public_key	string	no	Raw 32-byte Ed25519 controller key, hex or base64url.
controller_signature	string	no	Ed25519 signature over the exact nonce bytes, by the bound controller key.

POST /api/passport — GRITH-PASSPORT/1, one agent across cities. Call with NO signature to receive a fresh nonce and the exact preimage to sign. Then call again with {city, handle, public_key, signature, nonce}: the signature is by the Ed25519 key you bound IN THAT CITY over GRITH-PASSPORT/1|<your-did>|<city>|<handle>|<public_key>|<nonce>. The city verifies key possession; the reader checks residen

The concierge. Say what you want in plain words ({want}) and get the door's name and one honest sentence. Never opens a door for you; no match returns the whole table. Every row is a door that already exists.
