_ is it live, free and safe measured by this hub
Is perimeter-watch live?
Yes — it answered the hub's last check (checked 29m ago). It answered 99% of checks over the last 30 days.
Is perimeter-watch free to use?
Yes — the hub reached it with no key and no payment.
What tools does perimeter-watch have?
6 tools: read_skill, pw_snapshot, pw_watch_status, skills_list_tool, pw_health, pw_stats.
Is perimeter-watch 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.

_ what it can do 6 tools
3 open 3 never probed 3 of 6 classified

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.

  • skills_list_tool reads open 14h ago

    List this product's skills. Each entry carries the SKILL.md URI, its name and description, verbatim frontmatter, and a per-file sha256 manifest. Read a body with `read_skill`.

    mcp-tool

    {
      "type": "object",
      "title": "skills_list_toolArguments",
      "properties": {}
    }
    arguments 5 lines
  • pw_health reads open 14h ago

    Liveness check for the Perimeter Watch API. Returns ok, service, version. Call first to verify connectivity before pw_snapshot.

    mcp-tool

    {
      "type": "object",
      "title": "pw_healthArguments",
      "properties": {}
    }
    arguments 5 lines
  • pw_stats reads open 14h ago

    Service funnel counters: page views, snapshots run, paid registrations. Read-only.

    mcp-tool

    {
      "type": "object",
      "title": "pw_statsArguments",
      "properties": {}
    }
    arguments 5 lines
  • read_skill reads unknown 10h ago

    Read a product skill file by its skill:// URI. Args: uri: e.g. skill://<product>/<skill-name>/SKILL.md Get valid URIs from `skills_list_tool`.

    mcp-tool

    {
      "type": "object",
      "title": "read_skillArguments",
      "required": [
        "uri"
      ],
      "properties": {
        "uri": {
          "type": "string",
          "title": "Uri"
        }
      }
    }
    arguments 13 lines
  • pw_snapshot reads unknown never probed

    Run a free one-time external-perimeter scan on a domain you control. Checks TLS certificate expiry, domain renewal status, dangling CNAME takeover risk, and CT-log lookalike domains. Returns a rating plus per-check detail. NOT idempotent (each call consumes rate limit); takes 20-60s; rate-limited to 3 scans per IP per 24h. Args: domain: the domain to scan (e.g. example.com) authority: MUST be true — attests you or your principal own/manage this domain. Scanning third-party domains without authority is prohibited. Scan takes 20-60s. Rate limit: 3/IP/24h.

    mcp-tool

    {
      "type": "object",
      "title": "pw_snapshotArguments",
      "required": [
        "domain",
        "authority"
      ],
      "properties": {
        "domain": {
          "type": "string",
          "title": "Domain"
        },
        "authority": {
          "type": "boolean",
          "title": "Authority"
        }
      }
    }
    arguments 18 lines
  • pw_watch_status reads unknown 10h ago

    Check whether a domain is enrolled on a paid weekly monitoring plan. Returns enrollment status. Paid plans add weekly re-scans with email briefs. Read-only lookup. Args: domain: the domain to look up (e.g. example.com)

    mcp-tool

    {
      "type": "object",
      "title": "pw_watch_statusArguments",
      "required": [
        "domain"
      ],
      "properties": {
        "domain": {
          "type": "string",
          "title": "Domain"
        }
      }
    }

_ 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 2fe0544bc8a76017.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/2fe0544bc8a76017/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.
