Get PostgreSQL server connection information including version, database name, server time, and the current database user. Useful for verifying connectivity and understanding the database environment.
AI agents call connectionInfo to retrieve information from Postgresql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool exclusively queries system metadata to verify database connectivity and environment state. It performs no writes, executions, deletions, or financial operations. The information returned (version, database name, server time, current user) is informational only and does not alter any state.
From the tool's definition Tool retrieves connection metadata: 'PostgreSQL server connection information including version, database name, server time, and the current database user.' Returns read-only diagnostic information with no data modification, no code execution, and no…

Get PostgreSQL server connection information including version, database name, server time, and the current database user. Useful for verifying connectivity and understanding the database environment. It is categorised as a Read tool in the Postgresql MCP Server, which means it retrieves data without modifying state.
Register the Postgresql MCP server in PolicyLayer and add a rule for connectionInfo: 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 Postgresql. Nothing to install.
connectionInfo 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 connectionInfo 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 connectionInfo. 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.
connectionInfo is provided by the Postgresql MCP server (vnikhilbuddhavarapu/postgresql-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
