Agent Messenger
Sign up

Connect an AI agent

Connect Claude, or another MCP-compatible agent, so it can read your chats and send messages on your behalf. There's no API key to copy — an agent signs in the same way you do, and approves access on a consent screen before anything happens.

Choose your agent

Select a name to jump straight to its instructions or current availability. Every agent that's available uses the same secure sign-in — there is no API key to copy.

Server address

Use this URL whenever an agent asks for a remote MCP server.

https://mcp.messengeragent.dev/mcp

Claude Code

  1. Run this command in a terminal: 
    claude mcp add --transport http agent-messenger https://mcp.messengeragent.dev/mcp
  2. Start a session and use a tool from it, or run /mcp. Claude Code opens the sign-in page in your browser automatically.
  3. Sign in with the same email/password or Google you use here, then approve access.

Codex

  1. Run this command in a terminal: 
    codex mcp add agent-messenger --url https://mcp.messengeragent.dev/mcp
  2. Codex prints a sign-in URL. Open it in your browser.
  3. Sign in with the same email/password or Google you use here, then approve access.

Cursor

  1. Add this to ~/.cursor/mcp.json (or .cursor/mcp.json in a single project): 
    {
    "mcpServers": {
      "agent-messenger": { "url": "https://mcp.messengeragent.dev/mcp" }
    }
  }
  2. From a terminal, run cursor-agent mcp login agent-messenger, or open a chat in Cursor and use a tool — either prompts you to sign in.
  3. Sign in with the same email/password or Google you use here, then approve access.

VS Code

  1. Open the Command Palette and run MCP: Add Server, choose HTTP, and paste the server address above — or add it directly to .vscode/mcp.json: 
    {
    "servers": {
      "agent-messenger": { "url": "https://mcp.messengeragent.dev/mcp", "type": "http" }
    }
  }
  2. Start a chat and use a tool from it. VS Code opens the sign-in page in your browser automatically.
  3. Sign in with the same email/password or Google you use here, then approve access.

Other MCP-compatible agents

This server supports OAuth 2.1 with PKCE and Client ID Metadata Documents, with Dynamic Client Registration as a fallback — so most MCP clients can connect without anything being pre-registered here first.

  1. Open the agent's settings and look for Connectors, Plugins, or MCP servers.
  2. Add a custom or remote server with the address above and choose OAuth authentication.
  3. Sign in with the same email/password or Google you use here, then approve access.

What an agent can do

Consent is split into three scopes, so you can grant exactly the access you mean to — an agent asking for more shows that plainly on the consent screen, it's never bundled in silently.

  • Read — connected accounts, chats, message history, contacts
  • Manage — create and organize contacts, tags and campaigns, without sending anything
  • Send — send messages from your connected accounts, and start or resume a campaign

A message to more than one recipient always has to be previewed first — the agent sees exactly who would receive it before anything goes out, and can't skip straight to sending. Every call an agent makes, and everything it sends, is written to your activity log.
