Registry code: f870190286a57686

api record

grabmail gives you a throwaway email address and lets you read what arrives at it.

Typical use: call create_inbox to get an address, use that address wherever a confirmation email is needed, then call wait_for_message to block until it arrives and read the code out of it.

_ what it can do 6 tools
1 open 5 never probed 1 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.

  • list_domains reads open 15h ago

    The public domains anyone may use. A domain of your own needs no account or key either — just an MX record pointing here. These public domains are on disposable-mail blocklists; if a form rejects them, see the premium pool noted in the result. With a paid key sent as Authorization: Bearer, the result also lists the premium-pool domain names.

  • wait_for_message reads unknown never probed

    Blocks until a new message arrives at the address, then returns it in full — the tool to use after submitting a sign-up form. Waits at most 25 seconds and then returns with timed_out set to true; call it again to keep waiting. Optionally waits for a message from a particular sender or with particular words in the subject, ignoring anything else that arrives.

    arguments 31 lines
  • list_messages reads unknown 15h ago

    Everything waiting at an address, newest first. Returns immediately, including when the mailbox is empty — use wait_for_message if you are expecting something that has not arrived yet.

    mcp-tool

    {
      "type": "object",
      "required": [
        "address"
      ],

    }
    arguments 23 lines
  • create_inbox reads unknown never probed

    Invent a fresh, unused disposable email address you can give out immediately. Nothing is created or reserved server-side — an address exists as soon as mail arrives at it — so this never fails and needs no account. Public domains: grabmail.io, mixozia.com, linqmail.com. With a paid key sent as Authorization: Bearer, a premium-pool domain from list_domains works too.

    mcp-tool

    {
      "type": "object",
      "properties": {
        "domain": {
          "type": "string",
          "description": "Which domain to use: a public domain (grabmail.io, mixozia.com, linqmail.com), or, with a paid key, one of the premium-pool domains returned by list_domains. Defaults to grabmail.io."
        },
        "prefix": {
          "type": "string",
          "maxLength": 40,
          "description": "Optional readable prefix; a random suffix is added so it stays unique."
        }
      },
      "additionalProperties": false
    }
    arguments 15 lines
  • delete_message changes data unknown never probed

    Remove a message now rather than waiting for it to expire. Idempotent.

    mcp-tool

    {
      "type": "object",
      "required": [
        "address",
        "id"
      ],
      "properties": {
        "id": {
          "type": "string"
        },
        "address": {
          "type": "string",
          "description": "The full address, e.g. [email protected]"
        }
      },
      "additionalProperties": false
    }
    arguments 17 lines
  • read_message reads unknown 15h ago

    The full message: sender, subject, plain text, HTML and any attachments. This is where a confirmation code or a sign-in link will be. Read `text`: when the sender shipped HTML only, as most transactional mail does, it holds a plain-text rendering of that HTML rather than nothing, with link targets and image alt text kept.

    mcp-tool

    {
      "type": "object",
      "required": [
        "address",
        "id"
      ],
      "properties": {
        "id": {
          "type": "string",
          "description": "The message id from list_messages or wait_for_message."
        },
        "address": {
          "type": "string",
          "description": "The full address, e.g. [email protected]"
        }
      },
      "additionalProperties": false
    }
    arguments 18 lines
_ 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 f870190286a57686.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/f870190286a57686/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.
