FastMCP vs martin-loop
FastMCP: FastMCP is a Python framework that simplifies the creation of applications adhering to the Model Context Protocol (MCP), enabling AI agents to connect seamlessly with tools and data. It streamlines complex protocol implementation, focusing on delivering the right information to agents at the right time.; martin-loop: MartinLoop is a governance layer for AI coding loops that enforces budget caps, verifier gates, rollback evidence, and audit trails. It prevents unbounded retries by stopping unsafe or uneconomical work before execution, providing visibility and accountability for autonomous coding agents.
