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.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.

  • create_inbox 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, plimbox.com, mavobox.com, plupmail.com, zonkbox.com, wazbox.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, plimbox.com, mavobox.com, plupmail.com, zonkbox.com, wazbox.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
  • list_domains unknown never probed

    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.

  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • list_messages unknown never probed

    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"
  ],
  "properties": {
    "limit": {
      "type": "integer",
      "default": 50,
      "maximum": 200,
      "minimum": 1
    },
    "before": {
      "type": "string",
      "description": "Cursor from a previous call, to read older messages."
    },
    "address": {
      "type": "string",
      "description": "The full address, e.g. [email protected]"
    }
  },
  "additionalProperties": false
}
    arguments 23 lines
  • read_message unknown never probed

    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
  • wait_for_message 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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "address"
  ],
  "properties": {
    "address": {
      "type": "string",
      "description": "The full address, e.g. [email protected]"
    },
    "since_id": {
      "type": "string",
      "description": "Ignore this message and anything older; pass the newest id you have already seen."
    },
    "from_contains": {
      "type": "string",
      "description": "Only accept a message whose sender contains this."
    },
    "timeout_seconds": {
      "type": "integer",
      "default": 25,
      "maximum": 25,
      "minimum": 1
    },
    "subject_contains": {
      "type": "string",
      "description": "Only accept a message whose subject contains this."
    }
  },
  "additionalProperties": false
}
    arguments 31 lines
  • delete_message 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
}

_ 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ 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.
