Selfe — The Registry

https://selfe.ai

Registry code: c5c5816b4678d72a

api record

Selfe — The Registry answers questions about places to stay, eat and do, and books them, for AI agents. Use discover_venues for an open question (ranked places with evidence, recommended areas, and live availability when a stay is given or stated), match_venues when the user means specific places (by id or by name, with live offers when given a stay), and book_venue with a place id and an offerId from either. Every tool returns structured JSON, NOT a rendered UI. Never invent prices, availability or amenities — quote only what the results carry, and when match returns candidates, ask the user…

What tools does Selfe — The Registry have?
3 tools: book_venue, discover_venues, match_venues.
Is Selfe — The Registry safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 3 tools
3 never probed 0 of 3 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • book_venue unknown never probed

    Reserve a venue offer grounded by match_venues. Pass entityId and the selected offerId. The guest must approve every booking themselves, signed in to their Selfe account: the first call returns status 'approval_required' with approval.url for the guest to open; once they have approved, call again with the same offer and approvalId. A signed mandate alone cannot confirm a booking. No money moves at this step. Returns a confirmation (bookingId) or a conversational next step. Structured JSON.

  • discover_venues unknown 10h ago

    Search for places to stay, eat and do from a natural-language question. Returns ranked places, recommended areas, and — when you pass `stay` (or the question states dates and party) — live availability whose offer ids go straight to book_venue. Use match_venues instead when the user names a specific place. Structured JSON, not a rendered UI.

  • match_venues unknown 10h ago

    Get full details for places the user already means — by id (from discover_venues) or by name, with an optional website and town to tell same-named places apart. Pass `stay` to get live rooms and offers whose offer ids go straight to book_venue. A name that fits several places returns candidates: ask the user which, never guess. Structured JSON, not a rendered UI.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id c5c5816b4678d72a.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/c5c5816b4678d72a/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
