# Pega Code Review MCP Server

MCP server for exploring Pega branches and fetching full rule XML (LSA-style reviews).

**Auth:** Uses your existing browser session (no client ID / secret).

## Tools

| Tool | Purpose |
|------|---------|
| `pega_list_branches` | List available branches |
| `pega_get_branch_rules` | List rules inside a branch |
| `pega_get_rule_xml` | Fetch full XML of a rule by `pzInsKey` |
| `pega_get_referenced_rules` | Fetch XMLs of referenced rules |

## How to get your session token

1. Open your Pega app in the browser and log in normally.
2. Open DevTools (F12) → **Network** tab.
3. Click any API request (look for `/api/` or `/prweb/`).
4. In **Request Headers** find `Authorization: Bearer ...`
5. Copy the whole value (including `Bearer ` or just the token).

Alternatively copy the cookies from **Application → Cookies**.

## Config

```env
PEGA_BASE_URL=https://your-pega-instance.com/prweb
PEGA_ACCESS_TOKEN=Bearer eyJhbGciOi...
```

## Claude / Cursor config

```json
{
  "mcpServers": {
    "pega-code-review": {
      "command": "python",
      "args": ["/absolute/path/to/pega-code-review-mcp/server.py"],
      "env": {
        "PEGA_BASE_URL": "https://your-pega-instance.com/prweb",
        "PEGA_ACCESS_TOKEN": "Bearer eyJhbGciOi..."
      }
    }
  }
}
```

**Note:** Tokens expire. When tools start failing with 401, just copy a fresh token from the browser.
