No such file or directory

Error message

No such file or directory

What it means

A generic sentinel error returned by ToolFSCd when userSession.Backend.Ls(path) fails for the target directory. It replaces whatever the real backend error was (missing directory, permission denial, backend outage), so the message may not reflect the actual cause; the faulting input is the resolved 'path' parameter.

Solutions

1. Verify the 'path' parameter resolves to an existing directory on the configured backend
2. Check backend credentials/permissions allow listing the target directory
3. Log or wrap the original Ls error so real causes (not_found vs permission denied) are distinguishable
4. Test the same path directly against the backend to isolate MCP-layer issues
