The Model Context Protocol (MCP) and Agent2Agent Protocol (A2A) are distinct Linux Foundation projects designed for different agent communication needs. MCP facilitates an agent's connection to its own tools and data, while A2A enables agents from different organizations or frameworks to communicate and coordinate. MCP recently updated its specification to be stateless, with its SDKs seeing significant download numbers. A2A has reached version 1.0, boasting a large number of supporting organizations and a growing community, with features like Signed Agent Cards for verifying agent identity. AI
