MCP Servers

talktoplanb-mcp

Lets AI assistants list chat rooms, read messages, and send messages on TalkToPlanB, a self-hosted WhatsApp-alternative messenger.

README

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

Open the developer portal: https://talktoplanb.duckdns.org/portal
Register / log in, create a key, and grant the messages:read and messages:send scopes.
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).
