What this project enables!!

AI Driven Embedded Project Threat Analysis

• Determine which device properties are applicable to your project
• Do threat analysis
• Generate a detailed project report and heatmap

uvx mitre-emb3d ai --repo <path-to-repo> --config config.toml map-properties
uvx mitre-emb3d ai --repo <path-to-repo> --config config.toml threat-analysis
uvx mitre-emb3d ai --repo <path-to-repo> --config config.toml gen-site

See the documentation & guides for more information on configuration https://mitre-emb3d.readthedocs.io/en/latest/guides/

CLI, MCP Server & TUI

You can use the CLI or MCP server or both to build your own solutions

• List device properties for a given category
• List threats for a given category
• List threats for a given device property
• List device properties for a certain threat
• List mitigations for a given threat
• Get detailed information about a threat
• Get detailed information about a mitigation
• A CLI - AI Agent first (returns JSON output) / For humans add --pprint to see beautiful ouput
• A TUI - Heatmap creation, reading & update (See TUI section below for screenshots)
• An MCP Server

Example -

$ uvx mitre-emb3d --pprint list-threats-for-category "Networking"
- TID-221: Authentication Bypass By Message Replay
- TID-222: Critical System Service May Be Disabled
- TID-310: Remotely Accessible Unauthenticated Services
- TID-316: Incorrect Certificate Verification Allows Authentication Bypass
- TID-317: Predictable Cryptographic Key
- TID-318: Insecure Cryptographic Implementation
- TID-401: Undocumented Protocol Features
- TID-404: Remotely Triggerable Deadlock/DoS
- TID-405: Network Stack Resource Exhaustion
- TID-406: Unauthorized Messages or Connections
- TID-407: Missing Message Replay Protection
- TID-408: Unencrypted Sensitive Data Communication
- TID-410: Cryptographic Protocol Side Channel
- TID-411: Weak/Insecure Cryptographic Protocol

Note --pprint (default is OFF, default output is JSON) for display

Heatmap TUI

You can use TUI to inspect & edit the Heatmap

# Make sure to initialize the heatmap
uvx mitre-emb3d heatmap init "MyProject" "Description of Project"

• Above command will create myproject-heatmap.json file in the local data directory

  • See https://specifications.freedesktop.org/basedir/latest/
  • e.g. on macOS & linux it will be in ~/.local/share/mitre-emb3d

• All the entries in the heatmap are set to NOT_INVESTIGATED

# Show the current state (and edit) using TUI
uvx mitre-emb3d heatmap tui MyProject

You can override the default data directory by setting MITRE_EMB3D_HEATMAP_JSON_STORAGE_DIR environment variable

Clicking on Threat Entry will open a screen that presents a Form, Information about Threat & Mitigations

MCP Server

At the moment only STDIO is supported

For your mcp.json add the server like this

{
  "servers": {
    "mitre-emb3d": {
      "command": "uvx",
      "args": ["mitre-emb3d", "mcp"]
    }
  }
}

Use mcp inspector to play with the MCP Server

npx -y @modelcontextprotocol/inspector uvx mitre-emb3d mcp
