CallNode MCP server

CallNode MCP server

Your CallNode phone numbers, inside your AI assistant.

CallNode hosts a Model Context Protocol (MCP) server at:

https://mcp.callnode.io/mcp

Sign in to it from claude.ai, Claude Desktop, ChatGPT, Claude Code, Cursor or VS Code, then tick the numbers the assistant may use. It can then:

• read your call and message history;
• send texts and picture messages;
• call or text your Phone Book contacts by name;
• once you switch calling on, place calls that the CallNode voice agent runs.

The server is hosted by CallNode, so there is nothing to install or run. This repository holds only the connection details: client configs, the registry entry and this README.

• What it can do, in plain words: https://callnode.io/integrations/mcp
• Every tool, permission, limit and error code: https://callnode.io/docs/mcp

Before you connect

1. Create an account at https://callnode.io/signup (no credit card to start) and get a number. Self-serve numbers are local and toll-free numbers in the US and Canada.
2. Open Dashboard → MCP Server, switch MCP access on, and tick the numbers an assistant may use. Every connection shares this one list; a number you did not tick cannot be read from or sent from.

Connect

You give the client only the server URL. It sends you to the CallNode consent page, and you approve. No token is created, and nothing secret is pasted into a file or a shell.

On the consent page you can untick permissions (sending, for example), choose a live or test connection, and set an hourly send cap. Afterwards the connection appears under Dashboard → MCP Server, and you can revoke it there at any time.

claude.ai and Claude Desktop

1. Open Settings → Connectors and choose Add custom connector.
2. Enter https://mcp.callnode.io/mcp as the server URL and continue. Leave the client id and secret fields empty.
3. Claude opens the CallNode sign-in page. Log in if asked, review the numbers and permissions, and approve.
4. Back in Claude, enable the connector in a chat.

ChatGPT

1. Enable Developer mode under Settings → Connectors → Advanced, then choose Create.
2. Enter https://mcp.callnode.io/mcp as the MCP server URL and pick OAuth for authentication. No client id or secret is needed, because ChatGPT registers itself.
3. Approve on the CallNode sign-in page, then add the connector to a chat.

Claude Code

Either use .mcp.json from this repository in your project, or run this once:

claude mcp add --transport http callnode https://mcp.callnode.io/mcp

Inside Claude Code, type /mcp, pick callnode and choose Authenticate. Approve in the browser.

VS Code (Copilot agent mode)

1. Save .vscode/mcp.json in your workspace, then start the callnode server. VS Code opens the CallNode consent page; approve.
2. In Copilot Chat, choose Agent mode and tick the callnode tools.

Cursor

1. Save .cursor/mcp.json in your project, or the same entry in ~/.cursor/mcp.json, then reload Cursor.
2. In Settings → MCP the server shows Needs login. Click it and approve in the browser.

Without a browser sign-in

For automations where a browser sign-in isn't possible, create a token connection in the dashboard. The snippets for each client are at https://callnode.io/docs/mcp#clients.

Tools

Each tool is bound to a permission you grant. A connection without that permission does not see the tool at all.

Shortened. The full README is on GitHub.
