Unfragile

The request "TestMcp" is ambiguous: it most likely means testing an MCP server. Several sources do that job: MCPJam tests, debugs and evaluates MCP servers and is open-source 1, sunpeak is an open-source MCP testing framework with E2E and visual tests in CI 5, and MCP Checkup runs a free online health check of an MCP server without an account 3. Which fits depends on whether you need a local test suite, an online check, or ongoing monitoring; the request does not say which platform or cons

A question back: Do you want to test a local MCP server during development, run a CI test suite, or check a hosted MCP server online?
