mcp-probe started as a small CLI for checking whether an MCP server starts and exposes tools.

That was useful, but after feedback from developers running real MCP servers in agent workflows, the gap became obvious:

A server can start, pass tools/list, and still fail every real tool call because OAuth, browser auth, or downstream permissions are broken.

So I shipped mcp-probe v1.0.0 as a CI-ready readiness gate for MCP servers.
