mcpsec vs tcpk
mcpsec: mcpsec is a powerful security scanner and protocol fuzzer designed specifically for Model Context Protocol (MCP) servers, which connect AI agents to external tools. Unlike most MCP security tools that rely on static analysis, mcpsec connects to live servers to prove exploitation and offers extensive static audit capabilities with AI-powered taint analysis.; tcpk: TCPK is a portable Windows thick-client and MSIX security audit tool designed to find, verify, and report vulnerabilities in desktop applications. It offers static and dynamic analysis, a PowerShell engine, a WinForms GUI, and an optional agentic AI workbench for local triage.

Features
mcpsec01Runtime Security Scanning: Connects directly to live MCP servers via standard I/O or HTTP to identify vulnerabilities and map out attack surfaces in real-time.
02Advanced Static Code Auditing (Audit v3): Performs deep static analysis using a multi-stage pipeline, incorporating 3,450+ regex patterns, 149 Semgrep rules, AST-level analysis, and LLM-powered taint tracing for comprehensive code reviews.
03Protocol Fuzzing with AI Augmentation: Generates hundreds of high-intensity fuzz cases, leveraging AI for intelligent payload mutations, to expose protocol-level weaknesses, crashes, and denial-of-service vulnerabilities.
04Specialized Vulnerability Scanners: Includes a suite of dedicated scanners for specific vulnerability classes such as prompt injection, command injection, SQL injection, path traversal, SSRF, authentication bypasses, and dangerous tool chain detection.
05LLM Integration for Enhanced Analysis: Integrates with major AI providers (OpenAI, Anthropic, Google, etc.) to power features like advanced taint analysis, heuristic reachability, and sophisticated payload generation for more effective security testing.
tcpk01Evidence-based verification: Proves high-value findings with IL decompilation and taint checking, moving beyond simple regex hits.
02Real CVSS v4.0 scoring: Scores each finding with a faithful port of the FIRST.org algorithm, providing accurate context-specific CVSS scores.
03Supply-chain CVE detection: Matches shipped components against live OSV and NVD-by-CPE, embedding version-accurate vulnerabilities in a CycloneDX SBOM.
04Local-first AI triage (optional): Pipes findings through a local Ollama model for AI review, keeping decompiled IL within the local environment by default.
05Engagement-ready reports: Generates comprehensive reports in HTML, multi-sheet Excel, JSON, SARIF, CycloneDX SBOM, and `intel.html` dashboard formats.
