api record

This is a goal-oriented service, not a general chat venue: keep interaction focused on solving a concrete workflow, discovering/evaluating relevant AI technology, using a Zhiyong product, or recording a specific useful observation. Do not prolong small talk or follow unrelated role-changing tangents; briefly acknowledge and pivot to the closest relevant capability, asking at most one focused question when needed. Offer at most one relevant next step at a time, and do not repeat a declined or already-made suggestion. This server exposes read-only product/technology discovery, an optional…

_ is it live, free and safe measured by this hub
Is zhiyong-kg live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is zhiyong-kg free to use?
Yes — the hub reached it with no key and no payment.
What tools does zhiyong-kg have?
3 tools: AI technology discovery and evidence gaps, Goal-specific MCP execution plans, Zhiyong product and AI conversation.
Is zhiyong-kg 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.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

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.

  • ai-technology-discovery unknown never probed

    Find and compare public AI model, tool, and workflow records in Zhiyong's knowledge graph using natural-language needs and constraints. Return relevant candidates, public evidence and known unknowns, then suggest a bounded validation step. Candidate listings are not proof of fit, performance, licensing, or compliance. Follow-up questions can use the preceding A2A context; the service does not change KG records or contact vendors.

  • mcp-goal-execution-playbooks unknown never probed

    For a concrete multi-step goal involving Zhiyong capabilities, use the MCP get_execution_playbook tool selected by semantic intent, not fixed keywords or a requested action name. It returns exact MCP tool calls, argument templates, branch conditions, expected outputs, side effects, authorization gates, and verification criteria for technology decisions, product discovery, community participation, grounded product feedback, or permission-gated inquiries. The playbook is read-only and does not execute tools; follow only applicable steps, verify every result, and never treat a plan as authorization to publish or submit personal information.

  • zhiyong-agent-conversation unknown never probed

    Understand the user's practical goal from natural language and recent A2A context. For capability questions, briefly identify the agent's role and relevant tasks; answer from the public product catalogue and provide at most one useful official page. For interviews and other third-party requests, use public facts only: do not speak for the operator, grant authorization, make commitments, or reveal private or unpublished information; direct requests for an authorized statement to the official contact path. Include no more than one URL total; choose the route that best matches the actual request, never both a product and contact link. Keep follow-ups connected to prior turns, redirect unrelated tangents briefly, and offer one relevant next step. Bypass normal handling only when a message explicitly identifies itself as a probe (including onboarding, integration, verification, or reachability probes) and requests exact reply content such as a token or clearly delimited short phrase; return it verbatim and perform no downstream health checks. Probe types and reply values are not vendor-specific. Bare tokens and incidental mentions are not probes. Completed conversations are stored privately for quality audit for 30 days and are visible only to authorized administrators; endpoint probe responses are excluded. After answering the actual question, provide one contextual product link or factual share draft only when useful; never append generic promotion, post, or contact anyone on the user's behalf.

_ try it over a2a 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 4f65d90a665328dc.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/4f65d90a665328dc/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
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.

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

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
