TalkToPlanB MCP Server

Let AI assistants (Claude Desktop, and any Model Context Protocol client) use TalkToPlanB — list chat rooms, read messages, and send messages.

It wraps the TalkToPlanB developer REST API and talks MCP over stdio.

Tools

Tool	Description
whoami	Account info for the current API key (user id, username, scopes).
list_rooms	List your group chats and direct messages (returns room ids).
read_messages	Read recent messages in a room (roomId, optional limit).
send_message	Send a message by roomId or toPhone (plus text).

1. Get an API key

1. Open the developer portal: https://talktoplanb.duckdns.org/portal
2. Register / log in, create a key, and grant the messages:read and messages:send scopes.
3. Copy the key (looks like ttpb_xxxxxxxx...).

2. Use it with Claude Desktop

Add this to your Claude Desktop config (%APPDATA%\Claude\claude_desktop_config.json on Windows, ~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "talktoplanb": {
      "command": "npx",
      "args": ["-y", "talktoplanb-mcp"],
      "env": {
        "TALKTOPLANB_API_KEY": "ttpb_your_key_here"
      }
    }
  }
}

Restart Claude Desktop, then try: “List my TalkToPlanB rooms” or “Send a TalkToPlanB message to +60123456789 saying hello.”

Environment variables

Variable	Required	Default
TALKTOPLANB_API_KEY	✅	—
TALKTOPLANB_BASE_URL	❌	https://talktoplanb.duckdns.org

3. Local development

cd mcp-server
npm install
npm run build      # compiles src → dist
TALKTOPLANB_API_KEY=ttpb_... npm start

4. Publish to npm (so npx talktoplanb-mcp works for everyone)

cd mcp-server
npm login
npm publish --access public

After publishing, you can list it on MCP registries (mcp.so, Glama, Smithery) — see ../marketing/listing-checklist.md.

Notes

• Requires Node.js 18+ (uses the built-in fetch).
• stdout carries the MCP protocol; all logs go to stderr.
• The server only does what your API key is allowed to do (its scopes).
