AI agents use export_cohort to create or modify resources in Trillboards DOOH Advertising. 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 export_cohort 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 Trillboards DOOH Advertising.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Export exposed audience cohort to a DSP for retargeting. Pushes MAID hashes from the campaign's exposed cohort to the specified DSP (The Trade Desk, DV360, or Meta). Creates or reuses a DSP segment. WHEN TO USE: - Activating DOOH-exposed audiences for retargeting on digital channels - Pushing cohorts to TTD, DV360, or Meta Custom Audiences - Measuring cross-channel retargeting lift RETURNS: - status: 'synced', 'no_cohort', 'credentials_missing', or 'empty_cohort' - destination: the DSP name - segmentId: internal segment ID - externalSegmentId: DSP-side segment ID - maidCount: number of MAIDs uploaded - accepted: number accepted by DSP Supported destinations: ttd, dv360, meta, cadent, mediaocean EXAMPLE: export_cohort({ campaign_id: "camp_abc123", destination: "ttd" }). It is categorised as a Write tool in the Trillboards DOOH Advertising MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Trillboards DOOH Advertising MCP server in PolicyLayer and add a rule for export_cohort: 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 Trillboards DOOH Advertising. Nothing to install.
export_cohort 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 export_cohort 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 export_cohort. 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.
export_cohort is provided by the Trillboards DOOH Advertising MCP server (https://api.trillboards.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
