WHAT IT DOES

What pg_batch_insert does on PostgreSQL MCP Server

AI agents use pg_batch_insert to create or update resources in PostgreSQL MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PostgreSQL MCP Server environment.

RISK

Why pg_batch_insert is rated Medium

This tool creates new data rows in a PostgreSQL database through batch insertion. It is a Write operation because it modifies data reversibly (rows can be deleted). The severity is medium because bulk inserts could impact data integrity if misused by an agent (e.g., inserting many unwanted rows), but the effect is reversible. Confidence is high due to explicit 'Insert' language in both name and description.

From the tool's definition Tool name contains 'insert' and description states 'Insert multiple rows in a single statement', explicitly describing data modification capability.

RECOMMENDED RULE

The rule that runs pg_batch_insert safely

PolicyLayer is an MCP gateway: it sits between your AI agents and PostgreSQL MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pg_batch_insert, this is the rule to start with:

pg_batch_insert Rate-limited

pg_batch_insert stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
