cursor-byok is an open-source local implementation of Cursor's backend that runs a gateway service on your machine, connecting the Cursor editor to your own OpenAI- or Anthropic-compatible model APIs. It lets you configure custom endpoints, API keys, and model IDs while preserving Cursor Agent features like tool calling, Skills, and MCP.

Use cases

• use my own API keys with Cursor instead of the built-in models
• connect Cursor to a custom OpenAI-compatible endpoint
• route Cursor requests through Anthropic or local providers
• keep Cursor Agent tool calling and MCP working with my own models
• benchmark model providers for time to first token and speed
• track token usage and cache hit rate for Cursor sessions

When to choose

• you want Cursor to use your own model API keys, endpoints, or self-hosted models
• you need model channels beyond those officially offered in Cursor
• you want local control over routing, credentials, and request parameters
• you want to measure and compare provider latency and throughput

When to avoid

• you are happy with Cursor's official model offerings and billing
• you need a fully managed cloud service rather than a locally run gateway
• you expect free model usage - connected APIs may still charge
