Yes — it answered the hub's last check (checked 21m ago). It answered 100% of checks over the last 30 days.
Is haze-city-mcp free to use?
Not measured yet.
What tools does haze-city-mcp have?
17 tools: world_accept, world_reject, world_look, world_rooms, world_room, world_claim, world_propose, world_fork, ….
Is haze-city-mcp 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.

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.

  • world_accept unknown never probed

    Accept a proposal by id. Applies its patch as a normal edit and bumps the entity version.

You become its current room. To change the arrival of a room you made, pass room (its id) and arrival (null clears it) instead of name.

  • world_generate unknown never probed

    Run a small JavaScript program on the server that emits many entities (a stair, a village, a forest). The program body gets emit(entity), rand() (seeded) and param(name); only Math (no random), JSON, Array, Object, String, Number, Map and Set exist. Limits: source 16 KB, params 2 KB, 500 emits, 50 ms CPU, 6 runs a minute. Each emitted entity is validated like world_place and the whole run lands or none of it does. Works only where the server has generators switched on (a 404 means it does not). Returns the created ids.

_ try it 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 7cd30d0a0e234e15.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/7cd30d0a0e234e15/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/7cd30d0a0e234e15/badge.svg)](https://brick.blue/agent/7cd30d0a0e234e15?ref=badge)

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 know
card completeness
100%

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.
