Inspect ad account health and first-party signal quality, then propose policy-gated optimizations for Meta ads.
Connects to Meta advertising accounts to diagnose event flow, match quality, and reconciliation gaps. Lets marketers review performance data, verify signal ingestion, propose budget or creative changes, and manage the approval workflow, all subject to workspace policies.
Try asking Muse: "Show me the health of my first-party conversion tracking over the last 30 days and suggest any creative tests I should run."

Not in Muse's Connectors list yet, but Muse can still use it. Copy the request below and paste it into Muse. Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

PlainRouter is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
get_arrivals_comparisonReturn counted arrivals beside Meta outbound clicks for the authorized workspace and selected trailing window. difference is arrivals.value minus claimed_clicks; positive means more arrivals than Meta outbound clicks. conversions.count counts retained logical conversions under thget_conversion_journeysRead credited conversion journeys for an authorized workspace. Plainrouter counts earned from its own journeys. Earned covers every selected conversion kind; claimed covers Meta Purchases only, possibly in another currency. The two are shown side by side and are never reconciled.get_cac_by_channelReturn Plainrouter-earned conversions by channel, with cost per earned conversion in each spend currency, using stored ad spend. Each currency's cac divides that currency's spend by all earned conversions in the row, so when a row has spend in more than one currency, no single vaget_signal_qualityRead stored conversion delivery outcomes, delivery gaps, retained identity presence, and journey coverage for an authorized workspace.

Paste this into Muse: "Use PlainRouter to help me. It is a free service with an MCP server at https://plainrouter.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust.

At the last check (November 13, 2026, 11:15 UTC) the endpoint was working, answering in 335ms. Over the last 7 days it answered 100% of health checks. It is checked every 15 minutes.
It was screened on September 24, 2026 with the result "screened, no issues found". Screening checks the domain against threat feeds and reads the tools for hidden instructions and requests for passwords or card numbers. It cannot see the server's code, so grant only the access you need.
It exposes 40 tools, including get_arrivals_comparison, get_conversion_journeys, get_cac_by_channel, get_signal_quality. For example, you could ask Muse: "Show me the health of my first-party conversion tracking over the last 30 days and suggest any creative tests I should run."
