dcp vs fastmcp
dcp: DCP is a compact protocol for LLM agents to control physical devices, using a static intent table and CBOR wire format. It is validated on ESP32 hardware and complements MCP by translating DCP ↔ MCP for zero-config integration with MCP hosts. The protocol emphasizes safety through intent-level commands and capability tokens.; 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.
