Cursor

Configure Cursor, the AI code editor, to route requests to your LLM through your agentgateway proxy.

Before you begin

• Agentgateway running at http://localhost:3000 with a configured LLM backend.
• Cursor installed (version 0.30 or later).

Example agentgateway configuration

# yaml-language-server: $schema=https://agentgateway.dev/schema/config
llm:
  port: 3000
  models:
  - name: "*"
    provider: openAI
    params:
      apiKey: "$OPENAI_API_KEY"
