OpenAI-compatible
Chat Completions, Responses, and Models endpoints are exposed at a standard local /v1 base URL.
One-click agent setup
Configure Composer 2.5, Grok 4.5, and other Cursor models for OpenCode, Codex, VS Code, Cline, Kilo Code, and pi from a single Agent Setup panel.
Works where agents already run
Set up in your favorite coding agents.
Start the local API, then wire Composer 2.5, Grok 4.5, and other Cursor
models into the agents you already use. Each one keeps its own shell loop and your
real project files — only the model route points at 127.0.0.1.

OpenAI-compatible
A standard local /v1 surface.
Point any OpenAI-compatible client at the local base URL and the familiar endpoints are right there — Models, Chat Completions, and Responses.
In your editor
OpenCode, building with Cursor models.
Composer 2.5, Grok 4.5, and the Fast variants show up as normal models in OpenCode — while the agent keeps its local filesystem and shell tools. Same flow in Codex and any tool with a custom provider.
