Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "zulipchat": {
      "command": "uvx",
      "args": [
        "zulipchat-mcp"
      ],
      "env": {
        "ZULIP_EMAIL": "your-value",
        "ZULIP_API_KEY": "your-value",
        "ZULIP_SITE": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add zulipchat --env ZULIP_EMAIL=your-value --env ZULIP_API_KEY=your-value --env ZULIP_SITE=your-value -- uvx zulipchat-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "zulipchat": {
      "command": "uvx",
      "args": [
        "zulipchat-mcp"
      ],
      "env": {
        "ZULIP_EMAIL": "your-value",
        "ZULIP_API_KEY": "your-value",
        "ZULIP_SITE": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "zulipchat": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "zulipchat-mcp"
      ],
      "env": {
        "ZULIP_EMAIL": "your-value",
        "ZULIP_API_KEY": "your-value",
        "ZULIP_SITE": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions

Is ZulipChat MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ZULIP_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.2) reached the registry 10 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

ZulipChat MCP Server

Model Context Protocol server for Zulip Chat. Connect Claude Code, Codex, Clio Coder, OpenCode, Copilot, Antigravity CLI, Gemini CLI, and other MCP clients to Zulip.

Quick Start · Setup Wizard · Integrations · Two-Tier Tools · Contributing

Quick Start

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

Configure this command in your MCP client to let the assistant read and write Zulip messages with the configured account.

Need a zuliprc? Zulip Settings > Personal > Account & privacy > API key — download the file, save it as ~/.zuliprc.

Interactive onboarding:

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

What This Does

ZulipChat MCP bridges any MCP-compatible AI assistant (Claude Code, Gemini CLI, Cursor, Windsurf, etc.) to your Zulip workspace. The assistant can:

Send and read messages — stream messages, DMs, replies, reactions
Search conversation history — full-text search with filters for sender, stream, time range
Resolve people by name — verify a unique recipient before sending; ambiguous names need clarification
Switch identities — post as yourself or as a bot, in the same session
Monitor activity — search recent messages, get stream info, check who's online
Bind sessions to Zulip topics — give long-running agent sessions a stable control topic
Receive ordinary bot mentions — an event-fed local inbox that your own host adapter polls to wake an agent and reply in the source topic, without /reply for conversation. The server is the transport; it does not launch or supervise coding agents
Reuse dated snapshots — short-lived message caches and rate-aware request admission reduce repeated API reads
Request approvals in-topic — owner replies with /approve REQUEST_ID or /deny REQUEST_ID in the session topic; each decision names the request it answers
Load Agent Skills — four packaged instructions for messaging, session control, notifications, and bounded work loops, available as local files and MCP Resources
Export agent packages — native host configuration and skills, Claude's hook/plugin assets, or an Agent Plugins 1.0.0 package

Agent setup

# Substitute another supported client as needed.

uvx --from zulipchat-mcp zulipchat-mcp-integrate export --client clio-coder \ --output-dir /absolute/path/to/project \ --zulip-config-file /absolute/path/to/.zuliprc --extended-tools

Exports support claude-code, codex, opencode, copilot, vscode, antigravity-cli, clio-coder, and generic. Add --mode plugin for a package. For several Zulip organizations, export once per organization with --server-id zulipchat- ; exports merge into one host configuration. Account state lives under ~/.local/state/zulipchat-mcp/. Host trust remains explicit; Clio configures MCP execution separately from plugin content. See the capability matrix, Clio guide, and complete workflow.

For read-only access, add --tool-profile read-only: discovery and execution both expose nine core reads or 23 extended reads. The default full profile retains 20/60 tools. See API coverage and efficiency for cache freshness, rate limits and the boundary between message transport and host execution. The live Luna experiment records normal mention-to-bot replies from a real Clio TUI driven by a private, unshipped host adapter. Other hosts were tested through exported configuration and fake-credential checks, not live sessions.

Two-Tier Tool Architecture

v0.6.0 introduced a deliberate split: 20 core tools by default, 60 tools when you need more.

Core Mode (default)

The 20 tools that cover most daily use:

Category	Tools
Messaging	`send_message`, `edit_message`, `get_message`, `add_reaction`
Search	`search_messages`, `get_streams`, `get_stream_info`, `get_stream_topics`
Users	`resolve_user`, `get_users`, `get_own_user`
Agent Comms	`teleport_chat`, `register_agent`, `ensure_agent_session`, `agent_message`, `request_user_input`, `wait_for_response`
System	`switch_identity`, `server_info`, `manage_message_flags`

Why 20 instead of 60? Fewer tools means faster tool selection, lower token overhead, and less confusion for the AI. Most tasks — sending messages, searching, reacting, and binding an agent session to Zulip — only need the core set.

Extended Mode

Need scheduled messages, event queues, file uploads, analytics, or advanced search?

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

Or via environment variable:

ZULIPCHAT_EXTENDED_TOOLS=1 uvx zulipchat-mcp --zulip-config-file ~/.zuliprc

Extended mode adds: toggle_reaction, cross_post_message, advanced_search, construct_narrow, get_scheduled_messages, manage_scheduled_message, get_drafts, create_draft, edit_draft, delete_draft, register_events, get_events, listen_events, upload_file, manage_files, get_daily_summary, manage_user_mute, get_user, get_presence, get_user_groups, and more.

Installation

Full per-client setup guide: docs/integrations/README.md

Claude Code

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

With dual identity (you + a bot):

claude mcp add zulipchat -- uvx zulipchat-mcp \

--zulip-config-file ~/.zuliprc \ --zulip-bot-config-file ~/.zuliprc-bot

Optional Claude hook bridge for lifecycle and approval routing:

uvx --from zulipchat-mcp zulipchat-mcp-hook \

--zulip-config-file ~/.zuliprc \ --zulip-bot-config-file ~/.zuliprc-bot

Optional Claude package export for project-local hooks, skills, and subagents:

uvx --from zulipchat-mcp zulipchat-mcp-integrate export \

--client claude-code \ --mode standalone \ --output-dir . \ --zulip-config-file ~/.zuliprc \ --zulip-bot-config-file ~/.zuliprc-bot

Gemini CLI

Add to ~/.gemini/settings.json under mcpServers:

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

Claude Desktop / Cursor / Any MCP Client

Add to your MCP configuration:

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

Configuration Options

Option	Description
`--zulip-config-file PATH`	Path to your zuliprc file
`--zulip-bot-config-file PATH`	Bot zuliprc for dual identity
`--extended-tools`	Register all 60 tools instead of the 20-tool core set
`--tool-profile {full,read-only}`	Filter discovery and enforce read-only Zulip calls; default: `full`
`--transport {stdio,http}`	Transport to serve on (default: `stdio`)
`--host HOST`	Bind host for HTTP transport (default: `127.0.0.1`)
`--port PORT`	Bind port for HTTP transport (default: `8000`)
`--auth-token TOKEN`	Bearer auth token for HTTP transport (or `ZULIPCHAT_HTTP_AUTH_TOKEN`)
`--allowed-host HOST`	Additional trusted HTTP hostname; repeat for multiple names
`--allowed-origin URL`	Additional trusted browser origin; repeat for multiple origins
`--unsafe`	Enable administrative tools (use with caution)
`--debug`	Enable debug logging
`--associate-existing-db`	Deliberately associate an unbound legacy database with the verified current account

Remote HTTP Transport

ZulipChat MCP supports stateless HTTP deployments under the MCP 2026-07-28 protocol:

# Run server over HTTP with bearer authentication

ZULIPCHAT_HTTP_AUTH_TOKEN=your-secret-token \ uvx zulipchat-mcp --zulip-config-file ~/.zuliprc --transport http --host 0.0.0.0 --port 8000 --allowed-host mcp.internal

Generate client integration snippets for remote HTTP connections:

uvx --from zulipchat-mcp zulipchat-mcp-integrate print --client claude-code --remote-url http://mcp.internal:8000/mcp --remote-token your-secret-token

HTTP startup requires a bearer token for non-loopback binds and validates Host and Origin headers. Configure --allowed-host for the hostname used by clients or a reverse proxy; terminate TLS at the proxy for remote connections. A token grants access to the configured Zulip account: deploy a separate instance per trusted account, rather than sharing it across unrelated users.

HTTP tools reject server-local file paths, outbound event callbacks, and switch_identity. Upload text with file_content or binary bytes with file_content_base64; download without download_path to obtain a URL. Use stdio for local file operations and runtime identity switching. Attachment deletion requires --unsafe.

Persistent state defaults to an account-scoped directory. An explicitly selected ZULIPCHAT_DB_PATH is associated with the normalized realm and user/bot principals; a different account cannot reuse it. Legacy state is left intact and requires deliberate association. See database migration.

Agent sessions, approvals, listener cursors, and default background-task storage remain local state. Use a single instance for these workflows. Separate DuckDB paths avoid writer conflicts but do not share session data; ordinary round-robin routing across such replicas is not supported. Legacy HTTP clients may also retain transport sessions.

AI Analytics & LLM Provider

AI-powered analytics tools (analyze_stream_with_llm, analyze_team_activity_with_llm, intelligent_report_generator) execute using a server-side Anthropic LLM provider:

Set ANTHROPIC_API_KEY on the server process for LLM generation.
Optionally set ANTHROPIC_MODEL to override the default model (claude-opus-5).
Without an API key, analytics tools return structured data summaries with llm_unavailable: true so your client assistant can analyze the data directly.
