Opik MCP Server

The official Model Context Protocol (MCP) server for Opik, the open-source LLM observability and evaluation platform, built by Comet. Plug your AI host (Claude Code, Cursor, VS Code Copilot, Codex, opencode, or any MCP client) directly into your Opik workspace: read traces, log scores, and save prompt versions, all from the chat. It runs locally over stdio via the published package.

People who work with llm observability and opik and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Opik MCP Server

before you install - you'll need

Set OPIK_API_KEY, OPIK_MCP_ANALYTICS_SOURCE before connecting. OPIK_WORKSPACE, COMET_URL_OVERRIDE are optional or environment-specific per the README.

Claude Code

claude mcp add comet-ml-opik-mcp -- npx -y opik-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "comet-ml-opik-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "opik-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
