update_lead · Smokeball MCP: Risk & Policy

WHAT IT DOES

What update_lead does on Smokeball

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

WHY IT NEEDS A POLICY

Why update_lead needs a policy

The tool creates or modifies data reversibly, fitting the Write category. Severity is medium because updating lead records in a law firm practice management system could affect client workflows, communications, and case tracking, but the changes are not irreversible and do not involve financial transactions or code execution.

From the tool's definition Tool description states 'Update a lead's status or notes' — this modifies existing data (lead status and notes fields) reversibly without deletion.

update_lead Rate-limited
