uni-msg MCP MCP server

The uni-msg MCP server allows AI assistants to interact with WhatsApp via the uni-msg platform. It provides tools to read device status, conversation history, contacts, and groups, as well as write capabilities to send text and media messages. It enables agents to summarize threads, check for pending replies, and draft responses based on context.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http uni-msg-mcp https://uni-msg.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add uni-msg-mcp --url https://uni-msg.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable uni-msg-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "uni-msg-mcp": {
      "url": "https://uni-msg.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "uni-msg-mcp": {
      "type": "streamableHttp",
      "url": "https://uni-msg.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start uni-msg-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "uni-msg-mcp": {
      "type": "http",
      "url": "https://uni-msg.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http uni-msg-mcp https://uni-msg.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "uni-msg-mcp": {
      "url": "https://uni-msg.com/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "uni-msg-mcp": {
      "serverUrl": "https://uni-msg.com/mcp"
    }
  }
