WHAT IT DOES

What add_idea does on Ad Lab

AI agents use add_idea to create or update resources in Ad Lab, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ad Lab environment.

RISK

Why add_idea is rated Medium

An AI agent can call add_idea faster than any human can review: one bad instruction and it creates or modifies resources in Ad Lab by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs add_idea safely

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

add_idea Rate-limited

add_idea 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.

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

FAQ

Questions about add_idea

What does the add_idea tool do? +

Required final handoff for every finished product ad: add the generated Creative Spec to the Ad Lab Ideas tab, optionally attaching a rendered image. The Creative Spec must include non-empty copy.headline and copy.primary_text. It is categorised as a Write tool in the Ad Lab MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_idea? +

Register the Ad Lab MCP server in PolicyLayer and add a rule for add_idea: 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 Ad Lab. Nothing to install.

What risk level is add_idea? +

add_idea is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_idea? +

Yes. Add a rate_limit block to the add_idea 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.

How do I block add_idea completely? +

Set action: deny in the PolicyLayer policy for add_idea. 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.

What MCP server provides add_idea? +

add_idea is provided by the Ad Lab MCP server (@577-tools/ad-lab-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
