The Model Context Protocol (MCP) is a communication protocol for AI agents to interact with services. The MCP specification has been updated to introduce a new transport mechanism, called Streamable HTTP, which simplifies how AI agents can interact with services by using a single HTTP endpoint for sending and receiving responses between the client and the server. This new transport method eliminates the need to manage separate endpoints for requests and responses, reduces complexity, and enables bi-directional communication between the server and clients. The MCP specification is rapidly evolving, and developers can start testing it today using tools like mcp-remote. With the introduction of Python language support in Cloudflare Workers, developers can now build MCP servers entirely written in Python, making it easier to bring their services into the AI ecosystem.
