create_timeslip · FreeAgent MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_timeslip does on FreeAgent MCP Server

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

WHY IT NEEDS A POLICY

Why create_timeslip needs a policy

Creating timeslips writes to financial/time-tracking records in FreeAgent. While not inherently destructive or financial (it doesn't move money directly), it modifies the permanent record of billable time and business operations. Medium severity reflects potential for workflow disruption if misused (e.g., creating false billing records), though the operation is reversible via delete_timeslip.

From the tool's definition Tool description states 'Create a new timeslip', which creates new data in the FreeAgent accounting system. The sibling tools include delete_timeslip and update_timeslip, confirming this is a write operation in a financial tracking context.
