AI agents use setActiveContext to create or modify resources in Cupix Compass. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call setActiveContext repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Cupix Compass.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access setActiveContext gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Save the user's active team and facility so subsequent tool calls can omit the team_domain / facility_key arguments. Args: team_domain: Team domain to remember (required unless clear=True). facility_key: Facility key to remember (required unless clear=True). clear: If true, delete the stored selection and ignore the other args. Returns: Human-readable confirmation message.. It is categorised as a Write tool in the Cupix Compass MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Cupix Compass MCP server in PolicyLayer and add a rule for setActiveContext: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Cupix Compass. Nothing to install.
setActiveContext is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the setActiveContext rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for setActiveContext. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
setActiveContext is provided by the Cupix Compass MCP server (https://7qc1f4ft9d.execute-api.us-west-2.amazonaws.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
