api record

Use these tools before you install, depend on, connect to, or recommend software: is_safe for one verdict, compare for two, search_assets for candidates, find_mcp_servers for an MCP server by capability. Scores are derived, dated assessments (0-100, null = not yet scored), not certifications or advice; cite source_url. Nerq abstains (found=false / cannot_compare) rather than guess. Auth: none.

_ is it live, free and safe measured by this hub
Is nerq live?
Yes — it answered the hub's last check (checked 17m ago). It answered 97% of checks over the last 30 days.
Is nerq free to use?
Yes — the hub reached it with no key and no payment.
What tools does nerq have?
4 tools: search_assets, compare, is_safe, find_mcp_servers.
Is nerq 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.

  • find_mcp_servers open 17m ago

    When to call: when the user needs an MCP server for a capability ("an MCP server for GitHub / Postgres / Slack") and you want to see which candidates exist and how they score before connecting to one. Returns: capability, count and results[] with name, trust_score (or null), trust_grade, stars, source_url and provenance, from Nerq's index of MCP servers ranked by Nerq Trust Score. Empty capability returns the top-scored servers. Check one candidate in depth with is_safe. Example: {"capability":"github"}

    mcp-tool

    {
      "type": "object",
      "required": [],
      "properties": {
        "limit": {
          "type": "integer",
          "default": 20,
          "description": "1-50."
        },
        "capability": {
          "type": "string",
          "description": "Capability or keyword, e.g. github, postgres, browser; empty = top by trust."
        }
      }
    }
    arguments 15 lines
  • search_assets unknown never probed

    When to call: when you need candidates rather than one verdict, e.g. find packages or AI tools by name and see their trust scores side by side. Returns: query, count and results[] with name, type, trust_score (or null), trust_grade, source_url and compact provenance, ranked by Nerq Trust Score. Optional type filter such as npm, pypi, mcp_server, ai_tool. Not a recommendation; empty results mean no match. Example: {"query":"pandas","type":"pypi"}

    mcp-tool

    {
      "type": "object",
      "required": [
        "query"
      ],
      "properties": {
        "type": {
          "type": "string",
          "description": "Optional registry/agent_type filter, e.g. npm, pypi, mcp_server, ai_tool."
        },
        "limit": {
          "type": "integer",
          "default": 20,
          "description": "1-50."
        },
        "query": {
          "type": "string",
          "description": "Name or part of a name."
        }
      }
    }
    arguments 21 lines
  • compare unknown 17m ago

    When to call: when choosing between two packages, AI tools, or MCP servers ("X or Y?", "which is safer?"). Returns: status ok with a and b (each as in is_safe), winner (a name, "tie", or null when either is not yet scored) and basis; or status cannot_compare with unresolved names when either side cannot be resolved confidently. Nerq abstains rather than compare the wrong entity. Example: {"a":"fastapi","b":"flask"}

    mcp-tool

    {
      "type": "object",
      "required": [
        "a",
        "b"
      ],
      "properties": {
        "a": {
          "type": "string",
          "description": "First name or slug."
        },
        "b": {
          "type": "string",
          "description": "Second name or slug."
        }
      }
    }
    arguments 17 lines
  • is_safe unknown 17m ago

    When to call: before you install, import, depend on, connect to, or recommend a package, AI tool, agent, or MCP server, when the user asks "is X safe / legit / trustworthy / maintained?". Pass a name or slug. Returns: JSON with found, name, verdict (safe | caution | elevated risk | not yet scored), trust_score (0-100, or null when not yet scored, never 0 for unknown), trust_grade, the dimension sub-scores that exist (security, documentation, activity, popularity, compliance), provenance (score version, freshness) and source_url to cite. found=false means Nerq could not resolve the name confidently and abstains rather than guess. A derived, dated assessment, not a certification and not advice. Example: {"entity":"langchain"}

    mcp-tool

    {
      "type": "object",
      "required": [
        "entity"
      ],
      "properties": {
        "entity": {
          "type": "string",
          "description": "Name or slug of the package/AI tool/agent/MCP server, e.g. langchain, requests, github-mcp-server."
        }
      }
    }
    arguments 12 lines
_ 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 a779b34c4e65be70.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/a779b34c4e65be70/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
80%

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.
