replace_company_tags · CATS MCP Server MCP: Risk & Policy

WHAT IT DOES

What replace_company_tags does on CATS MCP Server

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

WHY IT NEEDS A POLICY

Why replace_company_tags needs a policy

This tool modifies company metadata (tags) in a reversible manner. While it overwrites existing tags, the action can be undone by replacing them again with the previous values. This makes it a Write operation rather than Destructive. The severity is medium because tag manipulation could affect company organization, filtering, and workflows in the ATS, but doesn't directly delete data or cause financial transactions.

From the tool's definition replace_company_tags replaces existing tags on a company - modifies data (tags) associated with a company record, which is a write operation. The word 'replace' indicates modification of existing data rather than creation of new data or deletion of records.
