I built MCP Blockly for MCP's 1st Birthday hackathon: a full visual environment for creating real MCP servers with block based logic. Research shows that learners develop stronger understanding when they work hands on, so the goal here is to make MCP development something you can explore directly rather than only read about.
Under the hood, every block on the canvas is converted into live Python through a custom generator that rebuilds your MCP function signature, parameters, and logic on each edit. The AI assistant reads the entire workspace through a structured representation, plans multi step changes, creates and adjusts blocks, tests your tool with real inputs, and can even deploy the finished MCP server to your Hugging Face account.
