Overview
Quickstart
One key, three tools - the ten-minute path.
Step 1 - mint your key
Everything runs on one API key, and it starts with pfr_. It is issued and authorized in the same click, and the same key works for the editor, the MCP, the Git Bot and co-presence - you never need a second one.
Sign in with Google and press Create my key.
Free, and one click with Google. It works for the MCP, the Git Bot and your coding agent.
Get your API key →The key starts on the Free plan. What each plan includes lives on the plans page and in Plans & limits.
Step 2 - pick your surface
- Working in an IDE? Install the MCP - one config block adds the review tools to Cursor, Claude Code or any MCP client.
- Tackling a hard prompt with your team? Open the Prompt Editor - signing in is the setup.
- Want every prompt change reviewed on the PR? Deploy the Git Bot - a GitHub Action in your own CI, no Hosho GitHub App.
- Using Claude Code? Add co-presence and your agent joins you inside the editor.
Set it up with your coding agent
Point it at prompts.hoshoai.com/agent-guide - a page written for agents that carries every setup on this site verbatim. The one step it will hand back to you is minting the key: that takes a human with a Google sign-in, by design.
