Add a new contact to an existing client
AI agents use quickfile_client_insert_contacts to create or update resources in QuickFile MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your QuickFile MCP Server environment.
This tool creates a new contact record within an existing client, modifying the client's data structure reversibly. While it does not delete, destroy, or move money, it does create data that could affect business communications and client records. Severity is medium because adding unwanted contacts could lead to misdirected communications or operational confusion, but the action is reversible through deletion.
From the tool's definition Tool name contains 'insert' and description states 'Add a new contact to an existing client', which creates new data.
