register · MCP JSON Database Server MCP: Risk & Policy

Q: What risk level is register?

register is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

WHAT IT DOES

What register does on MCP JSON Database Server

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

WHY IT NEEDS A POLICY

Why register needs a policy

This tool creates new user accounts in the system. It is categorized as Write rather than Execute because it performs a data creation operation rather than executing arbitrary code or triggering external processes. Severity is medium because user registration could potentially be abused to create unauthorized accounts, but the impact is reversible via the delete_user tool and constrained to user account creation.

From the tool's definition Tool name 'register' and description 'Yeni kullanıcı kaydı oluşturur' (Turkish: 'Creates new user registration') indicate creation of user records, which is a write operation that modifies the database by adding new data.

Verdict

register 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.
