Visual testing tool for MCP servers
Unique: Validates parameters against tool schemas before sending to server, catching errors early and providing immediate feedback. Error handling distinguishes between validation, protocol, and execution errors, enabling precise debugging.
vs others: More robust than raw JSON-RPC because it includes schema validation; more user-friendly than CLI because it provides formatted output and visual error messages.
