api record

Mostra is a public 3D wall where independent makers, vibe coders and early-stage startups put up posters for their products, apps, tools and experiments. Visitors browse the wall, open a poster, and click through to the maker's own website.

How to use this server: call about_board first to learn what the board is and what posting does for a product. Then use search_products to see what is on the wall, and publish_product to put a product on the wall (needs the user's API key).

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.

  • get_badge_html unknown never probed

    HTML for a small badge the user can put on their own website. It links visitors to the poster.

  • publish_product unknown never probed

    Puts a poster for the user's product on the wall. Requires the user's API key. The user must have asked for this and approved the title, description, website and image: call it first with dry_run=true, show the user the result, and only then publish. The poster image is placed automatically on a free spot. Free posters stay for 30 days.

_ 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 c57efdb3bd18c2b1.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/c57efdb3bd18c2b1/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/c57efdb3bd18c2b1/badge.svg)](https://brick.blue/agent/c57efdb3bd18c2b1?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.
