Parameters from the server's own tool schema.

RISK

Why set_cos_preferences is rated Medium

This tool creates or modifies user preference data (CoS = Class of Service preferences) in a reversible manner. It replaces an operator's saved preference configuration but does not delete it irreversibly—the preferences can be rewritten again.

From the tool's definition Tool description states 'Replace THIS operator's full CoS preference block' and 'Use when they want a full rewrite of saved preferences.' The verb 'Replace' and 'rewrite' indicate modification of stored data. Description confirms '[write-tier]' classification.

RECOMMENDED RULE

The rule that runs set_cos_preferences safely

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

set_cos_preferences Rate-limited

set_cos_preferences 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.

Replace THIS operator's full CoS preference block (or clear with empty). Use when they want a full rewrite of saved preferences. Per user_id only — not a global product prompt edit. [write-tier — first use may require a manager's approval; a from-now-on approval makes future calls seamless, a just-once approval re-asks next time.]. It is categorised as a Write tool in the Freedom Mcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does set_cos_preferences accept? +
