Every MCP client therefore fails during connection setup. This is **not** an `npx` startup-timeout problem: running the entry point directly with `node` fails identically, on every published version. ## Versions tested | Version | Exit code | `tools/list` | |---|---|---| | 1.0.21 | 1 | no response | | 2.0.5 | 0 | no response | | 2.0.7 | 0 | no response | | 2.0.8 | 1 | no response | | 2.0.9 (latest) | 1 | no response | ## Environment - Node.js ## Literal error text ``` Server exits immediately after initialize handshake and never responds to tools/list ``` ## Version info 1.0.21, 2.0.5, 2.0.7, 2.0.8, 2.0.9, v22.23.1 ## Environment GitHub issue benborla/mcp-server-mysql #150; state=OPEN ## Trigger / context ## Summary The stdio server answers the MCP `initialize` request and then terminates roughly 0.4 s later, without ever replying to `tools/list`.
