create_record · MCP Template MCP: Risk & Policy

WHAT IT DOES

What create_record does on MCP Template

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

WHY IT NEEDS A POLICY

Why create_record needs a policy

This tool creates new data entries, which is a reversible write operation. It does not delete, destroy, or move money (thus not Destructive or Financial), nor does it execute arbitrary code or shell commands (thus not Execute). The medium severity reflects that creating records could have side effects depending on business logic and data constraints, but the operation itself is reversible through deletion or updates.

From the tool's definition Tool name is 'create_record' and description states 'Create a new record in a resource', which clearly indicates data creation functionality.

create_record Rate-limited

create_record 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.
