Supported File Types

Example Workflow

User: "Import my research paper at /home/user/research.pdf"
AI: ✅ File imported successfully!
    Memory ID: abc-123
    Tokens: 5000
    Strategy: root-child
    Sections: 3

User: "What does my research paper say about machine learning?"
AI: 🔍 Found 2 results for "machine learning":
    1. [Score: 0.892] Machine learning is a subset of artificial intelligence...
    2. [Score: 0.845] The paper discusses various ML algorithms including...

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
