Developer Preview
Get Kelra working with your agent.
Kelra runs locally on macOS 14 or later. Request access to the source, build the MCP, and connect it to Codex to start measuring screenshots.
Set up Kelra
Three steps to your first measurement.
These steps describe the current Codex path. The detailed commands and caveats live in the connection guide.
- 01
Request access
Ask for Developer Preview access. When access is granted, you’ll receive the source location and any preview instructions.
Email Kelra about access - 02
Build on your Mac
In the Kelra engine directory, use the Swift toolchain to build the local executable.
swift build -c release - 03
Connect to Codex
From the engine directory, register the built executable. Restart your Codex session and confirm Kelra’s five tools are listed.
Open the full connection guidecodex mcp add kelra -- "$PWD/.build/release/kelra-mcp" codex mcp list
Accounts and plans
Do I need a Kelra account?
No. The current local Developer Preview has no Kelra sign-in, checkout, or subscription. Access is coordinated by email, and the MCP runs on your machine.
If account-based or paid access launches, its setup steps and terms will appear here before you’re asked to sign up or pay.
