mcp-assert vs CADCLAW

mcp-assert: mcp-assert is a powerful tool designed to test MCP (Multi-Agent Communication Protocol) servers against the real protocol, eliminating the need for mocks or language-specific dependencies. It validates server responses against YAML-defined expectations, ensuring compatibility with all MCP clients.; CADCLAW: CADCLAW is an automated framework that assembles STEP CAD parts based on declarative specifications and then rigorously verifies the resulting assembly. It provides a suite of geometric and BOM checks to catch common design errors and ensure accuracy, akin to a 'pytest for mechanical design.'

Features

mcp-assert logomcp-assert
01Protocol-level testing without mocks: Connects to servers using real stdio/SSE/HTTP transport and full MCP handshake.
02YAML-driven assertions: Define expectations in YAML for deterministic output validation.
03Language and framework agnostic: Tests any MCP server regardless of its implementation language and integrates with various test runners (Vitest, pytest, etc.).
04Comprehensive audit and fuzzing: Automatically scans servers, classifies tool health, and throws adversarial inputs to find crashes.
CADCLAW logoCADCLAW
01Automated STEP Assembly: Assembles authored STEP parts using declarative specs, generating design inventories, BOMs, renders, and build sequences.
02Comprehensive Geometric Validation Gates: Integrates multiple automated checks like interference, adjacency, dimensional, orientation, floating parts, and structural analysis.
03BOM-vs-CAD Audit: Automatically audits Bill of Materials (BOM) JSON against the CAD assembly for quantity, type, and term mismatches, ensuring consistency.
04AI-Assisted Workflow Integration: Supports AI assistants for editing assembly specs and provides an MCP Server for direct interaction, returning inline images for visual verification.
05CI/CD Pipeline Integration: Easily integrates into CI/CD workflows to automate assembly validation, flagging errors with exit codes.
