can postman request mcp server?
I want to debug my mcp server interface by postman request, Is it available？
When I try to request my MCP server through postman post method，the response is error like this: { "jsonrpc": "2.0", "id": "server-error", "error": { "code": -32600, "message": "Bad Request: Missing session ID" } }
my request body is： { "jsonrpc": "2.0", "id": 1, "method": "call_tool", "params": { "session_id": "test-session-1", // 这里必须有 "toolCalls": [ { "name": "list_trace_files", "arguments": {} } ] }
