Troubleshooting

MCP tools not showing up

• Ensure OpenMemory backend is running: curl http://localhost:8080/health
• Check MCP config file path is correct
• Restart AI tool after configuration

Import fails

• Verify file path is absolute
• Check file permissions
• Ensure OpenMemory backend is accessible

Search returns no results

• Verify user_id matches the one used during import
• Check if content was actually imported
• Try broader search terms
