Zulip MCP Server

What it does

Zulip MCP Server bridges AI assistants like Claude to your Zulip workspace. Once connected, your AI can read channel history, post messages to streams, send direct messages, manage topic subscriptions, list users, and add emoji reactions — all through natural language instructions.

Tools

• zulip_list_channels — List available streams (public, private, or web-public) in the organisation
• zulip_post_message — Post a message to a named channel and topic
• zulip_send_direct_message — Send a DM to one or more users by email or ID
• zulip_add_reaction — Add an emoji reaction to any message
• zulip_get_channel_history — Fetch recent messages from a specific stream and topic
• zulip_get_topics — List all topics in a channel
• zulip_subscribe_to_channel — Subscribe the bot to a channel
• zulip_get_users — Retrieve the full user list for the organisation

Installation

Create a Zulip bot (Settings → Personal → Bots → Add a new bot), then add to claude_desktop_config.json:

{
  "mcpServers": {
    "zulip": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-zulip"],
      "env": {
        "ZULIP_EMAIL": "your-bot@example.zulipchat.com",
        "ZULIP_API_KEY": "your-bot-api-key",
        "ZULIP_URL": "https://example.zulipchat.com"
      }
    }
