## Error Handling Verification
The server correctly handles:
1. **ANSI Escape Codes**: Stripped from all output
2. **Stderr Noise**: Filtered patterns include:
- `[STARTUP]` profiler messages
- `Loading extension:` messages
- `Loaded cached credentials.` messages
- `YOLO mode is enabled.` notices
- `[ERROR] [ImportProcessor]...parcel` warnings
3. **Extension List**: Preserved when `keep_extensions=True`
4. **Non-zero Exit Codes**: Properly reported as errors
5. **Missing Executable**: Returns helpful error message
6. **Empty Output**: Returns "No output returned"
## Tools Tested
| Tool | Description | Status |
|------|-------------|--------|
| `run_gemini` | Execute prompts with options | ✅ Fully functional |
| `gemini_resume` | Resume previous sessions | ✅ Fully functional |
| `gemini_list_sessions` | List available sessions | ✅ Fully functional |
| `gemini_list_extensions` | List CLI extensions | ✅ Fully functional |

## Conclusion
The Gemini MCP Server passes all 40 tests with a **100% success rate**. The server is robust and handles:
- Various prompt types (math, code, knowledge, creative)
- Edge cases (special chars, unicode, empty prompts)
- Parameter variations (model, sandbox, yolo modes)
- Error conditions (noise filtering, ANSI stripping)
The MCP server is **production-ready** for integration with Claude Code.
