Using EDB Postgres AI and Amazon Bedrock AgentCore for semantic data layers
In short: This update outlines a method for building a semantic knowledge base directly within PostgreSQL using the AIDB extension. By indexing schema metadata and utilizing the Model Context Protocol (MCP), you can expose database tools to agents in Amazon Bedrock AgentCore while enforcing existing row-level security.

What changed?
- 1Integrates semantic knowledge bases directly into the operational PostgreSQL database.
- 2Uses COMMENT ON statements for semantic context and schema discovery.
- 3Exposes database functions as tools via a native MCP endpoint.
- 4Implements role-based access control and row-level security within Postgres for agent requests.
Why it matters
This architecture simplifies agent data access by removing the need for external catalog synchronization. It keeps governance logic inside the database, ensuring that agents adhere to existing data permissions defined in Postgres.
What it means for AI agents and contact centers
When building voice agents that query operational databases, test this pattern to see if native semantic indexing improves text-to-SQL accuracy compared to external vector stores. Compare the latency of direct Postgres-MCP integration against middleware-heavy approaches.
🧪 Worth Testing
It offers a clean way to manage governance for agents interacting with relational data.
