Feature & Specification Comparison

Specification	E Execution Evidence Lab Developer Tools	MCP Observatory KryptosAI Developer Tools
Summary	Free execution evidence for Python dependency and configuration failures. Agents can search exact errors, compare measured environments, retrieve reproducible tests with hashes, and optionally return outcomes. Tested examples cover NumPy/pandas ABI, SQLite thread access, Starlette/HTTPX TestClient, settings aliases and SQLAlchemy async IO. Client reports stay separate from lab evidence. Remote Streamable HTTP MCP, REST and WebMCP; no service API key or payment.	Regression testing for MCP servers. Auto-discovers servers from Claude configs, checks capabilities, invokes tools, detects schema drift between versions, and recommends new servers based on your environment. Works as both a CLI and an MCP server.
