What is HippoDid and how does it work with this MCP server?

HippoDid is a cloud memory service for AI agents. This MCP server connects your AI to HippoDid's API, letting you store and retrieve structured memories persistently across sessions using your own API key.

How do I set up authentication?

Get a free API key at https://app.hippodid.com/settings/api-keys, then set the HIPPODID_API_KEY environment variable. Optionally configure HIPPODID_CHARACTER_ID for default character routing and HIPPODID_BASE_URL if using a custom endpoint.

Is there a cost to use HippoDid?

The registry and README do not specify pricing details. Visit https://app.hippodid.com to check HippoDid's current pricing and free tier limits.

Can I use this with multiple AI agents or characters?

Yes. Set HIPPODID_CHARACTER_ID to route background sync to a specific character, but you can manage multiple character memories through the API by specifying different character UUIDs in requests.

What happens if the HippoDid API is unreachable?

The MCP server communicates via stdio and relies on network connectivity to https://api.hippodid.com (or your custom HIPPODID_BASE_URL). If the service is down, memory operations will fail—consider implementing retry logic in your agent.
