api record

Immutable agent diagrams. Zindex keeps every saved version exactly, so a diagram made in one conversation can be found, changed and rendered the same way later, from any MCP client.

Loop: diagram_find or diagram_create, then diagram_get, diagram_edit, diagram_render. Edits need baseRevision (the revision you last read) and a one-line message.

_ is it live, free and safe measured by this hub
Is zindex live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is zindex free to use?
No — it asks for a key or a login before it will serve.
What tools does zindex have?
9 tools: diagram_validate, diagram_get, diagram_create, diagram_edit, diagram_delete, diagram_share, diagram_find, diagram_render, ….
Is zindex 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.

  • diagram_get auth-required never probed

    Reads a saved diagram by id or key. The default outline is a header (id, title, revision, time, hash), the brief, recent versions, one element per line nested by container, and edges as 'id: from -> to'. view 'dsp' returns the scene JSON; 'mermaid' returns Mermaid to edit and send back to diagram_edit. revision or asOf reads an earlier version; knownRevision, only what changed since; elements, only those elements and their neighbors.

  • diagram_create auth-required never probed

    Saves a new diagram from a DSP scene or Mermaid text and returns its id, revision 1, content hash and chain hash. key is your stable name for it, unique in the account: repeating a create with the same key and content returns the existing diagram, not a copy. brief stores context for the next agent. Versions are kept until you delete the diagram or the account.

  • diagram_edit auth-required never probed

    Changes a saved diagram as a new revision; old revisions are kept. Give baseRevision (the revision you last read), a one-line message, and ops (typed operations, https://zindex.ai/schemas/ops.schema.json), mermaid (the whole diagram edited from view mermaid; only differences apply), restoreRevision (an earlier version back), or brief. An edit with an error saves nothing; one that changes nothing returns noop. requestId makes a retry return the first result. A conflict lists what changed.

  • diagram_share auth-required never probed

    publish makes a diagram readable by anyone at its link; unpublish makes it private. link makes a share link showing its images, not its scene, to anyone who has it; unlink revokes them all. report sends one version to Zindex support. feedback sends Zindex staff a bug, docs (the docs and engine disagree), request or other; id or snippet attaches a diagram. Asks the user to confirm publish, link, report and feedback.

_ 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 2b00ac117e118cde.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/2b00ac117e118cde/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 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.
