Attackforge

An MCP server that connects AI assistants (Claude, etc.) to the AttackForge Self-Service API (SSAPI).

---

vs. the official AttackForge MCP

AttackForge publishes an official MCP server. It exposes a limited subset of the SSAPI — specifically: whoami, get_file, count_projects, count_vulnerabilities, count_writeups, find_affected_assets, find_projects, find_writeups, find_vulnerabilities, and get_field_structure.

This server covers the full SSAPI and adds a layer of context efficiency on top, designed specifically for use inside long AI conversations:

	Official MCP	attackforge-mcp
API coverage	10 endpoints	Full SSAPI
Response passthrough	Raw API JSON	Slimmed (see below)
HTML fields	Returned	Stripped globally (−40–60% size)
List responses	Full objects	Summary projection + total/has_more envelope
Static data (form configs, testsuite library, project index)	Re-fetched every call	SQLite cache with TTLs
Cache management	—	cache tool (stats, invalidate)
Escape hatch	—	raw_request for any unlisted endpoint

Why it matters: Large tool responses dump hundreds of lines of JSON into context on every call. Over a multi-step engagement that context fills up fast. By stripping HTML duplicates, projecting summary fields, and caching data that never changes mid-engagement, this server keeps each tool response as small as possible without losing information.

Setup

Requirements

• Python 3.12+
• uv

Install

git clone https://github.com/unstrike/attackforge-mcp
cd attackforge-mcp
uv sync

Configuration

Set two environment variables before starting the server:

Variable	Description	Default
AF_HOSTNAME	Your AttackForge instance hostname	(required)
X_SSAPI_KEY	Your SSAPI key	(required)

Run

AF_HOSTNAME=your.attackforge.com X_SSAPI_KEY=your-key uv run attackforge-mcp

Or add to your MCP client config (e.g. Claude Desktop claude_desktop_config.json):

{
  "mcpServers": {
    "attackforge-mcp": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/attackforge-mcp", "attackforge-mcp"],
      "env": {
        "AF_HOSTNAME": "your.attackforge.com",
        "X_SSAPI_KEY": "your-key"
      }
    }
  }
}
