When building MCP-based platforms, testing usually means manually crafting JSON-RPC requests or writing custom clients.
I built MCP Smoke as a lightweight test harness where you can:
Send real MCP requests using plain English
Simulate real user/agent interactions
Test tools, prompts, and resources end-to-end
Plug in API keys and hit actual MCP servers
It’s useful if you're building MCP platforms and want:
Faster iteration during development
Realistic testing instead of mocked flows
Observability/analytics on how your MCP server behaves
Would love feedback on what kind of test scenarios or validations should be added.
