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.

  • list_groups auth-required never probed

    List WhatsApp groups a device belongs to, with their JIDs. Use the JID as the "to" value in send_message to post to a group.

    mcp-tool

    {
  "type": "object",
  "required": [
    "deviceId"
  ],
  "properties": {
    "deviceId": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 12 lines
  • list_contacts auth-required 1h ago

    List saved contacts, optionally filtered by a search term.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "limit": {
      "type": "number",
      "description": "Default 25, max 100."
    },
    "search": {
      "type": "string",
      "description": "Match against name or number."
    }
  },
  "additionalProperties": false
}
    arguments 14 lines
  • list_conversations auth-required 1h ago

    List recent WhatsApp conversations for a device — who has been in touch and when. Use this to find the "peer" value that read_thread needs.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "limit": {
      "type": "number",
      "description": "Default 50, max 500."
    },
    "search": {
      "type": "string",
      "description": "Match against name or number."
    },
    "deviceId": {
      "type": "string",
      "description": "Optional. Omit to span all devices."
    }
  },
  "additionalProperties": false
}
    arguments 18 lines
  • list_devices auth-required 1h ago

    List the WhatsApp devices on this account with their connection status. Use this first — every send needs a deviceId, and only a device whose status is "connected" can deliver a message.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • get_device_status auth-required never probed

    Check one device: whether it is connected, and when it was last seen. Use when a send fails, to tell a disconnected device from a bad recipient.

    mcp-tool

    {
  "type": "object",
  "required": [
    "deviceId"
  ],
  "properties": {
    "deviceId": {
      "type": "string",
      "description": "Device id, e.g. dev_abc123"
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • read_thread auth-required never probed

    Read the message history with one contact or group. "peer" is the other party's phone number or JID, as returned by list_conversations. Returns newest first; use page to go further back.

    mcp-tool

    {
  "type": "object",
  "required": [
    "deviceId",
    "peer"
  ],
  "properties": {
    "page": {
      "type": "number",
      "description": "Default 1."
    },
    "peer": {
      "type": "string",
      "description": "Phone number or JID of the other party."
    },
    "limit": {
      "type": "number",
      "description": "Default 30, max 100."
    },
    "deviceId": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 25 lines
  • create_device auth-required never probed

    Register a new WhatsApp number so it can be paired. Step 1 of 3: create_device, then connect_device to get a pairing code, then the user enters that code on their phone. Creating a device may consume a slot on the account's plan, so check list_devices first rather than creating a duplicate for a number that already exists.

    mcp-tool

    {
  "type": "object",
  "required": [
    "name",
    "phoneNumber"
  ],
  "properties": {
    "name": {
      "type": "string",
      "description": "A label for this device, e.g. \"Sales line\"."
    },
    "phoneNumber": {
      "type": "string",
      "description": "The number to pair, in international format, e.g. +971501234567."
    }
  },
  "additionalProperties": false
}
    arguments 18 lines
  • connect_device auth-required never probed

    Step 2 of 3. Starts a session and returns an 8-character pairing code (and sometimes a QR string). Give the user the code and these exact instructions: on the phone holding that number, open WhatsApp → Settings → Linked devices → Link a device → "Link with phone number instead", then type the code. The code expires in about two minutes; if it lapses, call request_pairing_code for a fresh one rather than connect_device again. After they enter it, poll get_device_status until it reports connected.

    mcp-tool

    {
  "type": "object",
  "required": [
    "deviceId"
  ],
  "properties": {
    "deviceId": {
      "type": "string",
      "description": "From create_device or list_devices."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • request_pairing_code auth-required never probed

    Issue a fresh pairing code for a device that is already connecting. Use this when the previous code expired — it is cheaper and more reliable than tearing the session down and starting again.

    mcp-tool

    {
  "type": "object",
  "required": [
    "deviceId"
  ],
  "properties": {
    "deviceId": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 12 lines
  • disconnect_device auth-required never probed

    End a device session. The number stays registered and can be reconnected later, but it stops sending and receiving immediately, so confirm with the user before calling this.

    mcp-tool

    {
  "type": "object",
  "required": [
    "deviceId"
  ],
  "properties": {
    "deviceId": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 12 lines
  • send_message auth-required never probed

    Send a WhatsApp text message. The recipient may be a phone number in international format without "+" (e.g. 971501234567), or a JID for a group (…@g.us) or LID (…@lid). Sends immediately — there is no undo, so confirm the recipient with the user before calling this.

    mcp-tool

    {
  "type": "object",
  "required": [
    "deviceId",
    "to",
    "content"
  ],
  "properties": {
    "to": {
      "type": "string",
      "description": "Phone number in international format, or a JID."
    },
    "content": {
      "type": "string",
      "description": "Message text, up to 4096 characters."
    },
    "deviceId": {
      "type": "string",
      "description": "Which device sends it. See list_devices."
    }
  },
  "additionalProperties": false
}
    arguments 23 lines
  • send_media auth-required never probed

    Send an image, video, audio clip or document by public URL. The URL must be reachable by uni-msg — a local file path will not work. Sends immediately; confirm the recipient first.

    mcp-tool

    {
  "type": "object",
  "required": [
    "deviceId",
    "to",
    "kind",
    "mediaUrl"
  ],
  "properties": {
    "to": {
      "type": "string",
      "description": "Phone number in international format, or a JID."
    },
    "kind": {
      "enum": [
        "image",
        "video",
        "audio",
        "document"
      ],
      "type": "string"
    },
    "caption": {
      "type": "string",
      "description": "Optional. Ignored for audio."
    },
    "deviceId": {
      "type": "string"
    },
    "fileName": {
      "type": "string",
      "description": "Optional, for documents."
    },
    "mediaUrl": {
      "type": "string",
      "description": "Publicly reachable https URL."
    }
  },
  "additionalProperties": false
}
    arguments 40 lines
  • upsert_contact auth-required never probed

    Create a contact, or update it if the number already exists. Matching is by phone number, so this will not create a duplicate.

    mcp-tool

    {
  "type": "object",
  "required": [
    "phoneNumber"
  ],
  "properties": {
    "name": {
      "type": "string"
    },
    "email": {
      "type": "string"
    },
    "phoneNumber": {
      "type": "string",
      "description": "International format, no \"+\"."
    }
  },
  "additionalProperties": false
}
    arguments 19 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.

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.
