log_activity · Inkwell MCP Server MCP: Risk & Policy

WHAT IT DOES

What log_activity does on Inkwell MCP Server

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

WHY IT NEEDS A POLICY

Why log_activity needs a policy

This tool creates new activity records associated with CRM contacts. It is a write operation (creating data) that is reversible in principle (records can be deleted). The blast radius is medium because misuse could pollute CRM contact histories with false or misleading activity logs, affecting sales/support workflows.

From the tool's definition 'Log an activity' against a CRM contact — creates a new activity record (call, email, meeting, note, task, sms)

Verdict

log_activity Rate-limited

log_activity 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.
