insert_multiple_data · PySqlit MCP: Risk & Policy

WHAT IT DOES

What insert_multiple_data does on PySqlitMCP

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

WHY IT NEEDS A POLICY

Why insert_multiple_data needs a policy

This tool creates new data records in a SQLite database by performing batch inserts. While it modifies state, inserts are reversible through delete operations (which this server also supports via delete_data). The 'multiple' aspect increases the potential blast radius compared to single inserts, warranting medium severity.

From the tool's definition Tool name 'insert_multiple_data' and description indicating batch insertion of data into tables. The description translates to 'Batch insert data into a table.' This is a create/modify operation that adds multiple records.
