Review changes. Launch tests. ### Launch Reuse an existing Meta ad with your selected creative. Review the proposal, then create an approved copy paused. New image uploads support JPEG and PNG. Activate the finished ad in Meta when you are ready; Plainrouter does not activate ads in this release. [Learn about Launch](/product/launch) ### Actions Let agents prepare creative proposals while you keep approval control. Supported creative changes require human approval in every execution mode. Plainrouter executes approved image uploads and paused ad copies, then verifies the result. Budget and status recommendations cannot execute in this release. [Learn about Actions](/product/actions) ### Signals Collect consent-aware first-party events, pair browser Pixel and server Conversions API delivery, and see what Meta accepted. Acceptance does not prove ad attribution or guarantee better campaign performance. [Learn about Signals](/product/signals) ## Keep agents inside your guardrails Let agents prepare creative changes while you keep approval control. Plainrouter checks your rules, executes approved work, and verifies the result in Meta. - **Approval-gated.** You decide what agents can change. - **Verified.** Confirm every approved change landed in Meta. ## Connect your agent to Meta Ads with MCP Follow the canonical [Meta Ads MCP setup guide](https://plainrouter.com/docs/mcp/setup) to connect an agent and check account access.

Plainrouter connects Meta conversion tracking, campaign evidence, and approved creative changes through its API, SDKs, CLI, and MCP server. ### Does every ad change need manual approval? Yes. Supported creative changes require human approval in every execution mode. Agents can prepare JPEG or PNG uploads and paused ad copies; budget and status changes cannot execute in this release. ### Can Launch create an active ad? No. Approved ad copies are created paused. Review and activate them in Meta when you are ready; Plainrouter does not activate ads in this release. ### Does Signals replace my existing Meta Pixel and CAPI setup? For the events you move to Signals, the managed snippet pairs Meta Pixel and Conversions API delivery. Validate the new setup, then remove other integrations sending those same events to the same dataset. ### How do I know a change actually landed in Meta? Plainrouter records the provider receipt and follows it with verification reads. A request being accepted and the intended provider state being confirmed remain separate outcomes. ## From explanation to implementation - [Resources](/library): practical Meta conversion tracking guides. - [Documentation](https://plainrouter.com/docs): API references, SDK setup, and integration guides.
