Quickstart
Sign up, point your IDE at Agent Handler, and call a real GitHub tool. Both paths below sign you in through your IdP - no API key required.
You’ll need an Agent Handler account and an MCP-capable client (Cursor, Claude Code, Windsurf, VS Code).
If the agent is doing the signup and there’s no person to click through it, take the agent quickstart instead: one unauthenticated request creates the org, the key, a tool pack, and a registered user.
Connect Agent Handler
Pick one path.
Option A: MCP
First, sign in to the Merge CLI (one-time). The MCP server uses your Merge credentials:
Then add Agent Handler to your client. The first connection opens your browser for OAuth.

Option B: Merge CLI
For Claude Code, Cursor, or any agent that reads AGENTS.md. The setup command is idempotent, safe to re-run from any project root.

Pick the setup that fits your product. Use cases compares the three side by side.
The paths above sign you in through your IdP. When your own backend starts calling Agent Handler, it authenticates with an Access Key instead. Your production key is organization-wide, so once you serve real users, hand agents a user-scoped key minted from it rather than the key itself.
