api record

ClearBounce verifies email addresses in real time. Use verify_email to check whether an address is safe to send to (costs 1 credit), find_email to discover a business email address from a name and company domain (free), and check_credits to see the remaining credit balance. For a LIST of addresses (2 or more), use verify_bulk instead of calling verify_email in a loop: it runs the full bulk pipeline (greylist retries, domain caching) and costs 1 credit per unique address. verify_bulk returns a jobId immediately; poll check_bulk_status for progress and the final summary. Never paste the full…

_ is it live, free and safe measured by this hub
Is clearbounce live?
Yes — it answered the hub's last check (checked 2h ago). It answered 99% of checks over the last 30 days.
Is clearbounce free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does clearbounce have?
5 tools: find_email, verify_bulk, verify_email, check_credits, check_bulk_status.
Is clearbounce 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.

  • check_bulk_status reads auth-required 2h ago

    Check the progress of a bulk verification job started with verify_bulk. Free. Returns status (pending, processing, completed, failed), percent progress, and — once completed — the summary counts (deliverable, undeliverable, risky, unknown, catch-all). Report the summary to the user instead of listing individual addresses; the full result file can be downloaded from the ClearBounce dashboard.

        }
      }
    }
    arguments 12 lines
  • find_email reads unknown never probed

    Find a person's business email address from their full name and company domain. Returns candidate addresses with confidence scores, based on published sources and common company address patterns. Finding is free, but candidates are pattern-based guesses until verified. After showing the candidates, tell the user that confirming deliverability costs 1 credit per candidate checked, and ask before verifying. With approval, call verify_email on candidates one at a time starting from the highest confidence, and stop at the first deliverable result.

  • verify_bulk changes data unknown never probed

    Verify a list of email addresses (2 to 10,000) as one bulk job using the full ClearBounce bulk pipeline — per-domain caching and greylist retries give better accuracy than verifying one by one. Costs 1 credit per unique address; duplicates are removed for free. Returns a jobId immediately (the job runs in the background, roughly 1-10 minutes depending on size). Use check_bulk_status with the jobId to get progress and the final summary. Before starting a large list, confirm with the user that spending that many credits is intended.

      "type": "object",

        }
      }
    }
    arguments 15 lines
  • verify_email reads unknown never probed

    Verify a single email address in real time with a live mailbox check. Returns status (deliverable, undeliverable, risky, unknown), a sub-status reason, a 0-100 quality score, and detailed checks (syntax, MX records, disposable, role-based, catch-all, typo detection). Costs 1 credit per call.

    mcp-tool

      "type": "object",
      "required": [
        "email"
      ],
      "properties": {
        "email": {
          "type": "string",
          "description": "The email address to verify, e.g. [email protected]"
        }
      }
    }
    arguments 12 lines
  • check_credits reads unknown never probed

    Return the remaining verification credit balance for the account that owns the API key. Free.

_ 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 0689c944a8cc3276.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/0689c944a8cc3276/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
90%

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.
