Get started
Agent skills
Install evaluation expertise with one command. Your agent learns how to
build test suites, design judges, and run evals on Calibrate.
Guided onboarding
Run
/onboard and your agent walks you through setting up a complete
evaluation from scratch — connect, test, run, calibrate.MCP server
Connect the Calibrate MCP server for native tool access in Claude Code,
Cursor, Codex, and other MCP clients.
CLI
The Calibrate CLI gives agents structured JSON output for scripting
evaluations in any terminal.
How agents use Calibrate
Skills are the knowledge layer; the MCP server, CLI, and API are the execution layers underneath. Combine them — skills teach your agent what a good evaluation looks like, and the CLI (which the skills drive) runs it.
The skills drive the cloud CLI,
while the MCP server exposes the same operations as native
tools — both wrap the public API, so you can mix
and match against the same workspace.
Supported agents
All you need is a Calibrate API key — create one under
Workspace settings → API keys
(see the API keys guide).
