Question 1

Where should I start: API, MCP, or Playground?

Accepted Answer

Start with Playground for quick testing, then use API docs for production integration. Use MCP if your agent framework supports tool-calling workflows.

Question 2

How do I authenticate API requests?

Accepted Answer

Pass your MemBrain API key in the request headers as documented in the API reference. Keep keys server-side in production.

Question 3

Which endpoint stores a memory and is it synchronous?

Accepted Answer

Use the Store a memory endpoint. Ingestion is asynchronous and returns a job id that you can poll for completion status.

Question 4

How do I search and traverse graph relationships?

Accepted Answer

Use search endpoints for semantic recall and graph endpoints for neighborhood expansion, path finding, and traversal across linked memories.

Question 5

Where can I test requests before coding integration?

Accepted Answer

Use the Interactive Playground under Docs to run request flows and inspect responses before wiring your app.
