`color`	object	—	New color, or null to clear
`tagId`	string	Yes	The tag ID to update

Parameters from the server's own tool schema.

RISK

Why update_tag is rated Medium

This tool modifies existing tag metadata (name and color) within the CRM system. These changes are reversible — tags can be renamed again or recolored to different values. While this affects data organization in a CRM serving service businesses, the impact is limited to tag metadata and does not constitute destructive action, financial risk, or code execution.

From the tool's definition Tool description states 'Rename or recolor an existing CRM tag' — these are modification operations that change tag properties reversibly. The verb 'update' combined with 'rename' and 'recolor' indicates data modification without deletion.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_tag safely

PolicyLayer is an MCP gateway: it sits between your AI agents and FavCRM, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_tag, this is the rule to start with:

update_tag Rate-limited

update_tag 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.

}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect FavCRM, apply this rule, and every update_tag call is checked against it from then on.
