Summary
Connects Claude to TalkToPlanB, a WhatsApp alternative messaging platform, via its developer REST API. You get four tools: whoami for account info, list_rooms to see your chats, read_messages to pull recent history from a room, and send_message to fire off texts by room ID or phone number. Needs an API key from the TalkToPlanB developer portal with messages:read and messages:send scopes. Runs via npx, talks stdio, and keeps all logging on stderr so it doesn't mess with the MCP protocol stream. Useful if you want Claude to monitor group chats or send notifications through TalkToPlanB without switching windows.

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
- Open the developer portal: https://talktoplanb.duckdns.org/portal
- Register / log in, create a key, and grant the
messages:readandmessages:sendscopes. - 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). stdoutcarries the MCP protocol; all logs go tostderr.- The server only does what your API key is allowed to do (its scopes).
