ZulipChat

ZulipChat MCP Server lets your AI assistant connect to Zulip and perform messaging, stream management, analytics, file operations, and workflow automation through a modular MCP (Model Context Protocol) interface. This enables powerful, context-aware interactions with your Zulip environment from your AI agent.

How to use

You use the Zulip MCP server by connecting an MCP client to it. Once connected, your AI assistant can perform actions across eight categories such as Messaging, Streams, Topics, Users, Search & Analytics, Events, Files, and System workflows. Start by configuring your MCP client to point at the server, then invoke tool endpoints or commands supported by the client to send messages, query streams, manage topics, retrieve analytics, upload files, listen for events, and execute automated workflows. The server handles authentication against Zulip using your provided credentials and exposes capabilities through a consistent MCP interface so your AI can act within Zulip with proper context.

How to install

Prerequisites: you need Python 3.10+ and the UV package manager. You will also need access to a Zulip instance and a zuliprc configuration file that contains your Zulip credentials.

uvx zulipchat-mcp --zulip-config-file ~/.zuliprc

If you prefer a wizard-assisted setup, run the setup flow to automatically locate zuliprc files, validate credentials, and generate the MCP client configuration.

uvx --from zulipchat-mcp zulipchat-mcp-setup

If you want to connect manually using a Zulip config file, you can use the following approach.

uvx zulipchat-mcp --zulip-config-file ~/.zuliprc

A sample MCP configuration for an MCP client can be added to your MCP config file as shown in the example below. This enables you to run the MCP server from a local command, such as during development or testing.

{
  "mcpServers": {
    "zulipchat": {
      "command": "uvx",
      "args": ["zulipchat-mcp", "--zulip-config-file", "/path/to/zuliprc"]
    }
  }
}

Configuration & troubleshooting

Configuration options you may encounter include specifying the zuliprc path, enabling a bot configuration file for dual identity, and toggling debugging or listener services. Use the following options when running the client or setting up the MCP config file: --zulip-config-file PATH, --zulip-bot-config-file PATH, --unsafe, --debug, and --enable-listener.

Common issues and their remedies include ensuring your Zulip credentials are correct, confirming the Zulip site URL uses https, and verifying your bot has permissions for the streams you intend to use. If a connection fails, validate the credentials and recheck the zuliprc file. If a module cannot be found, consider updating the UV toolchain and reinstalling the MCP package.

For troubleshooting, ensure the MCP client config is correctly referenced by the server and that the command or URL used to start the MCP server is valid and reachable.
