BurpMCP-Ultra is a native Kotlin Burp Suite extension with an embedded MCP (Model Context Protocol) server. It exposes Burp's Montoya API as 150 structured tools over a token-secured local SSE transport, so an AI agent can run proxy history analysis, active scans, fuzzing, race conditions, OOB testing, custom scan checks, and guided exploitation — all from natural language.

Quick Start

1. Build

git clone https://github.com/Cy-S3c/BurpMCP-Ultra.git
cd BurpMCP-Ultra
./gradlew shadowJar

Output: build/libs/burpmcp-ultra-2.3.1.jar (~13 MB). A JDK 17–21 must be installed — see Building from Source. Pre-built JARs are on the Releases page.

2. Load into Burp

1. Burp Suite Pro → Extensions → Add
2. Select the JAR
3. The BurpMCP-Ultra tab appears with a green "Running" status and your connection token

3. Connect Claude Code

{
  "mcpServers": {
    "burp": {
      "type": "sse",
      "url": "http://127.0.0.1:9876/",
      "headers": {
        "Authorization": "Bearer PASTE_TOKEN_FROM_SERVER_TAB"
      }
    }
  }
}

Add to ~/.claude.json or your project's .mcp.json.

⚠️ The token is required, and the endpoint is the root path / — not /sse. Copy the token from the Server tab of the BurpMCP-Ultra panel in Burp. Without it the server returns 401, and clients like Claude Code then fall back to OAuth discovery and fail with SDK auth failed: HTTP 404: Invalid OAuth error response.
