Explaining the Model Context Protocol

The MCP consists of many parts. In short, JavaScript Object Notation-Remote Procedure Call (JSON-RPC) messages are exchanged between the client and the server. A JSON-RPC message is a message following the JSON-RPC specification, which means it has the jsonrpc, id, method, and params fields, and the data type is JSON. An example could look like so:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "doSomething",
  "params": {
    "foo": "bar"
  }
}
