Why it matters
MCP-connected database agents are a growing attack surface for prompt injection and tool abuse, and this vendor guidance gives defenders concrete controls to harden agent-to-database interactions.
Google Cloud documentation lays out best practices for securing AI agent interactions with AlloyDB for PostgreSQL over the Model Context Protocol (MCP), covering least-privilege access, database-native granular controls, treating data and user inputs as untrusted, preventing unauthorized tool chaining, limiting access in multi-tenant databases, and enabling Model Armor safety thresholds plus auditing.
