Pydantic AI memory

Plan memory integration for Pydantic AI with a scoped Ditto graph and a repeatable retrieval test.

Guide in preparation. The setup below is a planning outline, not a tested framework implementation or a completed product comparison. Use the linked documentation for currently supported interfaces.

Choose the memory boundary

Decide what this Pydantic AI application should retain across runs. Create a dedicated graph for the project so the evaluation does not mix test data into your main memory.

Validate the connection

Use Ditto's documented MCP endpoint and authentication requirements. Confirm the transport and adapter supported by your installed Pydantic AI version before wiring tools into the agent. A framework-specific implementation guide is still pending validation.

Test across two runs

Save a harmless project decision in one run. In a separate run, retrieve it, inspect the stored record and verify the agent uses it. Check that the key cannot access an unrelated graph, then revoke test credentials.
