MCP Analyzer Server

A dedicated MCP (Model Context Protocol) server for security analysis and malicious tool detection.

Features

• analyze_mcp_tool: Enhanced context-aware security analysis for individual MCP tools
• batch_analyze_tools: Comprehensive security assessment for multiple tools at once
• Context-aware detection: Reduces false positives and negatives
• Behavioral pattern analysis: Identifies tool poisoning and covert operations
• Risk scoring: Provides detailed risk assessment with confidence levels

Installation

npm install
npm run build

Usage

Start the server

npm start
# or
node dist/mcp-analyzer.js

Test the server

echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/list", "params": {}}' | node dist/mcp-analyzer.js

Tools

analyze_mcp_tool

Analyzes a single MCP tool for malicious indicators.

Input:

• tool_name: Name of the MCP tool
• tool_description: Description of the MCP tool
• tool_input_schema: Input schema (JSON string, optional)

Output:

• Comprehensive security analysis report
• Risk level assessment (LOW/MEDIUM/HIGH)
• Malicious indicators detection
• Security recommendations

batch_analyze_tools

Analyzes multiple MCP tools at once for comprehensive security assessment.

Input:

• tools: Array of tools to analyze

Output:

• Batch analysis report for all tools
• Comparative risk assessment
• Security recommendations for the toolset

Security Analysis Features

• Context-aware detection: Uses semantic analysis to reduce false positives
• Behavioral pattern analysis: Identifies tool poisoning and covert operations
• Input schema analysis: Examines tool parameters for dangerous patterns
• Risk scoring: Provides detailed risk assessment with confidence levels
• Security recommendations: Offers specific mitigation strategies

Use Cases

• MCP tool security research: Analyze tools for malicious patterns
• Security assessment: Evaluate tool safety before deployment
• Compliance checking: Ensure tools meet security requirements
• Threat detection: Identify potentially dangerous MCP tools
