Pick a server and a question an assistant might be asked. You see the exact MCP tool call, the server's response and a readable view of it.
Every response was recorded from a real run of the server on the Kestrel demo files. Nothing runs live, and nothing you do on this page is sent anywhere.
Playground
Choose a server, then a question. Run replays the recorded call.
Run it yourself
Point your assistant at the Kestrel files and ask the same questions.
