peac vs fastmcp

peac: PEAC is an open standard for portable signed interaction records across APIs, MCP servers, x402 payment flows, and cross-runtime systems. It enables offline verification and survives organizational boundaries. Use it when local logs are insufficient and external verification is needed.; fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.
