Install the MCP

One config block adds hosho_improve_prompt to Cursor, Claude Code or any MCP client - the full review, findings and rewritten sections inline in your IDE. The key at the bottom is the only step that needs an account.

Hosho MCP

Score prompts, compare edits and check skill alignment, straight from your agent.

Already installed the co-presence plugin? The MCP came with it - nothing to do here. Follow the steps below if it isn’t working.

Add this to your MCP client config - ~/.cursor/mcp.json, or VS Code’s MCP settings.

{
  "mcpServers": {
    "hosho-prompt-review": {
      "url": "https://hosho-mcp-server.onrender.com/mcp",
      "headers": {
        "Authorization": "Bearer pfr_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
      }
    }
  }
}

That pfr_… is your API key - see Your API key below.

Using Claude Code? The plugin below installs these - skip this box. Same pfr_... key either way.

Your API key

The pfr_… in the config above - one key for the MCP, the Git and your coding agent. It starts on the Free plan - 5 review runs and 5 PR reviews a month, and unlimited checks.

Free, one click, and you come straight back to this page. The key is the only step that needs an account.
