mcp-semclone - Model Context Protocol Server for SEMCL.ONE

Apache-2.0 Python 3.10+ MCP 1.0+

MCP (Model Context Protocol) server that provides LLMs with comprehensive OSS compliance and vulnerability analysis capabilities through the SEMCL.ONE toolchain.

Overview

mcp-semclone integrates the complete SEMCL.ONE toolchain to provide LLMs with powerful software composition analysis capabilities:

  • License Detection & Compliance: Scan codebases for licenses and validate against policies
  • Binary Analysis: Analyze compiled binaries (APK, EXE, DLL, SO, JAR) for OSS components and licenses
  • Vulnerability Assessment: Query multiple vulnerability databases for security issues
  • Package Discovery: Identify packages from source code and generate PURLs
  • SBOM Generation: Create Software Bill of Materials in CycloneDX format
  • Policy Validation: Check license compatibility and organizational compliance

Features

Tools

Analysis & Scanning:

  • scan_directory - Comprehensive directory scanning for packages, licenses, and vulnerabilities
  • scan_binary - Analyze compiled binaries (APK, EXE, DLL, SO, JAR) for OSS components
  • check_package - Check specific packages for licenses and vulnerabilities
  • download_and_scan_package - Download package source from registries and perform deep license/copyright scanning

Legal Notices & Documentation:

  • generate_legal_notices - Generate legal notices by scanning source code directly (fast, recommended)
  • generate_legal_notices_from_purls - Generate legal notices from PURL list (downloads from registries)
  • generate_sbom - Generate Software Bill of Materials in CycloneDX format

License & Policy Validation:

  • validate_policy - Validate licenses against organizational policies
  • validate_license_list - Quick license safety validation for distribution types
  • get_license_obligations - Get detailed compliance requirements for licenses
  • check_license_compatibility - Check if two licenses can be mixed
  • get_license_details - Get comprehensive license information including full text
  • analyze_commercial_risk - Assess commercial distribution risks

Complete Workflows:

  • run_compliance_check - Universal one-shot compliance workflow for any project type

Resources

  • license_database - Access license compatibility information
  • policy_templates - Get pre-configured policy templates

Prompts

  • compliance_check - Guided workflow for license compliance checking
  • vulnerability_assessment - Guided workflow for security assessment

Installation

Single Command Installation

pip install mcp-semclone

This automatically installs all required SEMCL.ONE tools:

  • purl2notices - Comprehensive package detection and license extraction
  • osslili - License detection from archives (used by check_package)
  • binarysniffer - Binary analysis for OSS components
  • ospac - Policy validation engine
  • vulnq - Vulnerability database queries
  • upmex - Package metadata extraction (used by check_package)

Pipx Installation (Recommended for Global Access)

pipx installs the package in an isolated environment while making the CLI tools globally available. This is ideal for avoiding dependency conflicts with other Python packages on your system.

# Install pipx if you don't have it
pip install pipx
pipx ensurepath

# Install mcp-semclone
pipx install mcp-semclone

# IMPORTANT: Inject all SEMCL.ONE tool dependencies into the same isolated environment
# This ensures all tools are available both as libraries and CLI commands
# Required by some agents that need direct CLI tool access
# Use --include-apps to make CLI commands globally available
pipx inject mcp-semclone purl2notices purl2src osslili binarysniffer ospac vulnq upmex --include-apps

Benefits of pipx:

  • ✅ Isolated environment prevents dependency conflicts
  • ✅ All tools globally accessible in PATH
  • ✅ Easy to update: pipx upgrade mcp-semclone
  • ✅ Clean uninstall: pipx uninstall mcp-semclone

For detailed setup instructions including:

  • IDE-specific configurations (Cursor, Cline, Kiro, VS Code, JetBrains)
  • Auto-approve settings
  • pip vs pipx configurations
  • Configuration templates
  • Troubleshooting

Environment Variables

Optional environment variables for enhanced functionality:

# API Keys (optional, for higher rate limits)
export GITHUB_TOKEN="your_github_token"
export NVD_API_KEY="your_nvd_api_key"

# Tool paths (optional, only if tools are not in PATH)
# Tools are auto-detected by default using shutil.which()
export PURL2NOTICES_PATH="/custom/path/to/purl2notices"
export OSSLILI_PATH="/custom/path/to/osslili"
export BINARYSNIFFER_PATH="/custom/path/to/binarysniffer"
export VULNQ_PATH="/custom/path/to/vulnq"
export OSPAC_PATH="/custom/path/to/ospac"
export UPMEX_PATH="/custom/path/to/upmex"

Note: Tools are automatically detected in your PATH. Environment variables are only needed for custom installation locations.

Usage Examples

With MCP Clients

Once configured, you can ask your LLM:

  • "Scan /path/to/project for license compliance issues"
  • "Analyze this Android APK file for OSS components and licenses"
  • "Check if this project has any critical vulnerabilities"
  • "Generate an SBOM for my project"
  • "What licenses are in this compiled binary?"
  • "Validate these licenses against our commercial distribution policy"
  • "Find all GPL-licensed dependencies in this codebase"

Workflows

License Compliance Check

  1. Scan the project to identify all packages and licenses
  2. Load or create a policy defining allowed/denied licenses
  3. Validate licenses against the policy
  4. Generate compliance report with violations and recommendations

Vulnerability Assessment

  1. Discover packages in the codebase
  2. Query vulnerability databases for each package
  3. Prioritize by severity (CRITICAL > HIGH > MEDIUM > LOW)
  4. Identify available fixes and upgrade paths
  5. Generate security report with remediation steps

SBOM Generation

  1. Scan project structure to identify components
  2. Extract metadata for each component
  3. Detect licenses and copyright information
  4. Format as SBOM (CycloneDX 1.4 JSON)
  5. Validate completeness of the SBOM
