🎯 Overview

The MITRE ATT&CK MCP Server transforms the world's leading adversary knowledge base into an AI-native interface. Built for the Model Context Protocol, it enables LLMs and agentic systems to:

• 🔍 Query 200+ techniques, 140+ groups, 700+ software entries
• 🧠 Reason over complex threat relationships and TTPs
• 📊 Visualize coverage gaps with ATT&CK Navigator layers
• ⚡ Scale threat intelligence workflows with structured tools

Perfect for: Security teams, threat hunters, detection engineers, AI researchers, and anyone building intelligent security systems.

What is this?

mitre-attack-mcp-server is a self-contained MCP server that provides machine-callable access to the MITRE ATT&CK framework using official STIX data with LLMs friendly structured outputs.

It enables:

• 🤖 LLMs to reason about ATT&CK techniques, groups, software, and mitigations
• 🧠 Agentic workflows to generate threat explanations and coverage maps
• 🔍 Security teams to query ATT&CK relationships programmatically
• 📊 Visualization via ATT&CK Navigator layers

No scraping.
No fragile APIs.
Just official MITRE data, structured and reliable.

npx (no installation required)

npx @imouiche/mitre-attack-mcp-server

Via uv (Modern Python)

uv pip install mitre-mcp-server

Local Development

git clone https://github.com/imouiche/complete-mitre-attack-mcp-server.git
cd complete-mitre-attack-mcp-server
npm install

Using uv (Python package manager)

git clone https://github.com/imouiche/complete-mitre-attack-mcp-server.git
cd complete-mitre-attack-mcp-server
uv sync

⚡ Quick Start

1. Install

pip install mitre-mcp-server

2. Configure Claude Desktop

Add to your claude_desktop_config.json:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "mitre-attack": {
      "command": "npx",
      "args": ["-y", "@imouiche/mitre-attack-mcp-server"]
    }
  }
}

3. Restart Claude Desktop

Quit Claude Desktop completely (Cmd+Q on macOS) and reopen it.

4. Start Querying!

Ask Claude:

"What techniques does APT29 use for initial access?"
"Generate an ATT&CK Navigator layer for ransomware groups"
"Show me all Windows persistence techniques"

Data downloads automatically on first run (~59MB, cached at ~/.mitre-mcp-server/data/).

"Which groups target financial institutions?"
"Show me all ransomware-related software"
"What are the aliases for the Lazarus Group?"

Detection Engineering

"What data sources detect credential dumping?"

Mitigation & Defense

"What mitigations exist for phishing attacks?"
"Show me all mitigations for privilege escalation"
"What techniques does MFA mitigate?"

Compliance & Gap Analysis

"Generate a layer for all techniques our EDR covers"
"Compare APT29 TTPs against our detection capabilities"
"Show unmitigated techniques in our environment"

📊 ATT&CK Navigator Visualization

The generate_layer tool produces ATT&CK Navigator–compatible JSON.

Usage:

1. Ask Claude to generate a layer:

   "Generate an ATT&CK Navigator layer for all techniques used by APT29"

2. Save the JSON output to a file (e.g., apt29_layer.json)

3. Upload to ATT&CK Navigator

4. Visualize technique coverage, threat actor usage, or mitigation mapping
