Sendblue — iMessage, RCS & SMS MCP ServerVerifiedFeatured

Official Sendblue connector for sending and reading customer messages from MCP-compatible AI assistants over iMessage, RCS, and SMS.

Connect

Add a remote HTTP MCP server in your assistant using:

https://api.sendblue.co/mcp

Choose OAuth sign-in, sign in to your Sendblue account, select your workspace, and approve the requested access. The server supports OAuth 2.1 with PKCE and dynamic client registration. Do not put API keys or account passwords into the server URL or configuration.

{
  "mcpServers": {
    "sendblue": {
      "type": "http",
      "url": "https://api.sendblue.co/mcp"
    }
  }
}

Use a client that supports remote HTTP MCP and OAuth. Exact configuration syntax can vary by client.

Tools

Tool	What it does
ping	Checks connectivity to the authenticated workspace.
list_lines	Lists the workspace's sending lines.
list_messages	Reads recent messages and replies.
send_message	Sends a one-to-one text message through Sendblue.
get_message_status	Checks a message's delivery status.
evaluate_service	Produces a bounded messaging-health summary for the workspace.

Try it

• "List my Sendblue sending lines."
• "Show my recent Sendblue messages."
• "Send [message] to [opted-in recipient] from [my sending line]."
• "Check the delivery status of [message handle]."

Confirm the recipient, message, and sending line before sending. An accepted or queued message is not yet proof of delivery; check its status before retrying.

Account requirements

A Sendblue account is required. The connector also works with a free Sendblue account, subject to that plan's limits. Free shared-line accounts must verify recipients before sending. Messaging limits and account permissions continue to apply.
