Test Your Server with RPC Command​

Start the server, and paste follow message:

{"id":4,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{"experimental":{},"sampling":{}},"clientInfo":{"name":"weather","version":"1.0.0"},"_meta":{},"method":"initialize"},"jsonrpc":"2.0"}

Success response example:

{"jsonrpc":"2.0","id":4,"result":{"protocolVersion":"2024-11-05","capabilities":{"logging":{},"tools":{"listChanged":true}},"serverInfo":{"name":"my-weather-server","version":"0.0.1"}}}

Error response example:

{"jsonrpc":"2.0","id":4,"error":{"code":-32603,"message":"Unrecognized field \"_meta\" (class io.modelcontextprotocol.spec.McpSchema$InitializeRequest), not marked as ignorable (3 known properties: \"protocolVersion\", \"clientInfo\", \"capabilities\"])\n at [Source: UNKNOWN; byte offset: #UNKNOWN] (through reference chain: io.modelcontextprotocol.spec.McpSchema$InitializeRequest[\"_meta\"])"}}
