# Quickstart: Claude Code

**You need:** Claude Code, and an API key in `RA_API_KEY`.

1. **Get a key.** Sign up at https://app.closefinch.com/sign-up (the Free plan, no card). An owner creates a key in Settings → API keys and picks its scopes: `crm:read` to read, plus `crm:write` and `agents:write` to make changes. Keep it in an environment variable, never in a file you commit:

   ```bash
   export RA_API_KEY=ra_live_…
   ```
2. **Add the server** (for this project; use `--scope user` for all your projects):

   ```bash
   claude mcp add --transport http revenueagent https://api.closefinch.com/mcp --header "Authorization: Bearer $RA_API_KEY"
   ```

   The shell fills in `$RA_API_KEY`, so Claude Code stores the key itself in `~/.claude.json`: keep it at local or
   user scope, never `--scope project` (that file is shared). To keep only a reference, use the `ra` CLI instead:
   `ra install claude-code` writes the project's `.mcp.json` and a skill, which refer to `${RA_API_KEY}` and never
   contain the key.
3. **Check it.** Check it works: ask the assistant "Who am I in Closefinch?" It calls `ra_whoami` and answers with your organization, role and scopes.
