Visualize, inspect, and debug MCP server traffic with production‑ready UI components.
Stop guessing what your MCP server is doing. Start seeing every STDIO and SSE message in real time.
You know the pain: you’re wiring up a new MCP server, but you can’t see what’s actually happening. You’re tailing logs, re-running processes, manually parsing STDIO blobs, and adding print statements just to track tool calls. Streams freeze, messages go missing, and you have no UI to confirm what the server is really sending. It slows every project down.
The MCP Inspector Dashboard Kit fixes that by giving you a full set of production‑ready React + Shadcn components for visualizing, inspecting, and debugging MCP server traffic. You get tested STDIO and SSE connectors, event panels, stream viewers, capability inspectors, tool call explorers, and diagnostic overlays—ready to drop into any React project with zero custom wiring.
What’s Included:
- STDIOConnector with buffering, reconnection, and heartbeat handling
- SSEConnector with stream parsing, backoff timing, and dropped‑event detection
- MessageTimeline component for real‑time STDIO/SSE visualization
- ToolCallInspector for tracing arguments, responses, and error payloads
- StreamViewer for long‑running or high‑volume server streams
- CapabilityMap panel showing resolved and missing capabilities
- SessionDiagnostics module for detecting stale sessions and mismatched states
- SafeLogRenderer to prevent unsafe HTML, runaway payloads, and UI lockups
- Ready-to-use Shadcn layouts styled for dashboards and devtools
Built from patterns used to test and stabilize real MCP servers handling large payloads, long‑running tasks, and continuous streaming under production load. These are the same inspection tools used to uncover message‑ordering bugs, silent stream drops, and capability edge cases in active MCP integrations.
Who This Is For:
- MCP server developers who need a reliable UI to inspect STDIO/SSE traffic
- Tool builders validating long‑running calls, streams, and capability behavior
- Teams maintaining production MCP servers that must catch hidden issues quickly
Who This Is NOT For:
- Developers who only need a basic “hello world” MCP example
- Teams that don’t use STDIO or SSE transport and do all debugging through logs
If this doesn’t save you at least 4 hours of debugging and UI setup, reach out for a full refund.
