Overview

What is Orcarouter?

Orcarouter is the official MCP server for the OrcaRouter LLM gateway. It lets you browse OrcaRouter's model catalog and run chat completions from any Model Context Protocol (MCP) client such as Claude Desktop, Claude Code, Cursor, Windsurf, or Zed.

How to use Orcarouter?

Install and add the server to your MCP client. For Claude Code, run claude mcp add orcarouter -s user -e ORCAROUTER_API_KEY=sk-orca-your-key -- npx -y @orcarouter/mcp. For other clients, copy the example config file for your client (e.g., claude-desktop.json) into the client's config location, replace the API key placeholder, and restart the client. Node.js 18 or later is required.
