Requires running a PostgreSQL-backed service and connecting agents via the MCP protocol.

Copy-paste prompts

Prompt 1
Set up Memory Engine as an MCP server backed by PostgreSQL and connect it to my coding agent so it can remember project context across sessions.
Prompt 2
Show me how to store a memory in Memory Engine tagged 'design.auth' describing my app's authentication approach.
Prompt 3
How do I search Memory Engine in plain English to find memories related to how authentication works in my project?
Prompt 4
Explain how Memory Engine uses PostgreSQL's built-in extensions to do semantic and keyword search instead of a separate vector database.
