Get PostgreSQL database server information
AI agents call postgres_database_info to retrieve information from Multi-Database MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata or status information about a PostgreSQL database server without modifying, deleting, or executing arbitrary code. It is a read-only informational query with no side effects or destructive capability. The low severity reflects minimal blast radius—an AI agent querying database info cannot cause data loss, financial harm, or unauthorized modifications.
From the tool's definition Tool name 'postgres_database_info' and description 'Get PostgreSQL database server information' indicate a retrieval operation with no modification or deletion. The verb 'Get' confirms data retrieval only.
Attacks that exploit this kind of access
Get PostgreSQL database server information. It is categorised as a Read tool in the Multi-Database MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Multi-Database MCP Server MCP server in PolicyLayer and add a rule for postgres_database_info: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Multi-Database MCP Server. Nothing to install.
postgres_database_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the postgres_database_info rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for postgres_database_info. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
postgres_database_info is provided by the Multi-Database MCP Server MCP server (nam088/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
