kimi-api-mcp

MCP server for Kimi K2.5 via the Moonshot REST API — no CLI installation or subscription required. Just a Moonshot API key.

Works with Claude Code, Cursor, VS Code, Windsurf, Claude Desktop, and any MCP-compatible host.

Why

The official kimi-code-mcp package requires the Kimi Code CLI binary and a paid subscription. This package calls the Moonshot API directly using your existing API key — no binary, no subscription.

Related MCP server: firepass-mcp

Install

No install needed with npx:

npx kimi-api-mcp@latest

Or install globally:

npm install -g kimi-api-mcp

Setup

1. Get an API key from platform.moonshot.ai (free tier available)

2. Add to your MCP config
