context1337 — AboutSecurity MCP Server

Standalone MCP resource service that turns [AboutSecurity](https://github.com/wgpsec/AboutSecurity) from a file repo into a consumable API. Like context7, but for security.

Demo

**Search security resources** 

**Vulnerability intelligence** 

**AD domain attack skill detail** 

Quick Start

Docker (recommended)

# Default: clones AboutSecurity from GitHub automatically
make docker

# Use local AboutSecurity repo (skip git clone, faster rebuild)
make docker-local
# or specify path:
make docker-local ABOUTSECURITY_LOCAL=../AboutSecurity

# Pin to a specific branch/tag
make docker-ref ABOUTSECURITY_REF=dev

docker run -p 1337:1337 -e ABOUTSECURITY_API_KEY=your-key context1337:latest

Local Development (recommended for first-time users)

Only requires Go 1.25+ (gotip) and Python 3 installed on your machine.

git clone https://github.com/wgpsec/context1337.git
cd context1337

# One command does everything:
# 1. Clones AboutSecurity repo (if not already present)
# 2. Installs Python dependencies (jieba, pyyaml)
# 3. Builds FTS5 search index (builtin.db)
# 4. Compiles Go binary
# 5. Symlinks data directories
# 6. Starts the server
make run

# Build & run (requires data/ populated with builtin.db or AboutSecurity content)
make build
./absec serve --port 1337 --data-dir ./data  # default: --tool-mode lite

The server will be available at `http://localhost:1337`.
