Your Question

I would like to request complete examples for using the example MCP servers, I tried to run the mcp server on my localhost and curl to it for testing before connecting it with agents, but it keeps error out, e.g., for the example hello MCP server, i keep getting the following error:

curl -X POST http://localhost:8888/greet \
>   -H "Content-Type: application/json" \
>   -H "Accept: application/json,text/event-stream" \
>   -d '{
>     "jsonrpc": "2.0",
>     "method": "greet",
>     "params": {}
>     }'
JSON RPC not handled: "greet" unsupported

I did call:

curl -X POST http://localhost:8888 \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{
    "jsonrpc": "2.0",
    "method": "initialize",
    "params": {
      "protocolVersion": "2024-11-05",
      "capabilities": {
        "tools": {}
      },
      "clientInfo": {
        "name": "curl-client",
        "version": "1.0.0"
      }
    },
    "id": 1
  }'

and
curl -v -X POST http://localhost:8888 -H "Accept: application/json, text/event-stream" -d '{"jsonrpc":"2.0","method":"notifications/initialized"}'
