WHAT IT DOES

What meta_insights does on Hermoso

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

RISK

Why meta_insights is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs meta_insights safely

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

meta_insights Rate-limited

meta_insights 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 Hermoso, apply this rule, and every meta_insights call is checked against it from then on.

FAQ

Questions about meta_insights

What does the meta_insights tool do? +

Pull performance INSIGHTS (spend, impressions, reach, clicks, CTR, CPC, CPM, conversions) for a connected ad account, or a specific campaign / ad set / ad. Pass adAccountId (for auth); optionally objectId to scope to one object and level to break the numbers down. BREAKDOWNS are what make the numbers actionable — a flat total says an ad cost $X, never WHO it worked on: pass breakdowns:. It is categorised as a Write tool in the Hermoso MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on meta_insights? +

Register the Hermoso MCP server in PolicyLayer and add a rule for meta_insights: 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 Hermoso. Nothing to install.

What risk level is meta_insights? +

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

Can I rate-limit meta_insights? +

Yes. Add a rate_limit block to the meta_insights 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 meta_insights completely? +

Set action: deny in the PolicyLayer policy for meta_insights. 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 meta_insights? +

meta_insights is provided by the Hermoso MCP server (https://app.hermoso.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
