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
