Distinguish allocated asset value from post-install ROAS. Ad network MCP guide Connect Google Ads to Claude or ChatGPT with Lemon AI’s unified MCP and API. Distinguish allocated asset value from post-install ROAS. **To analyze Google Ads in Claude or ChatGPT, connect a reporting tool through MCP, then ask it to retrieve a specific account, date range, and set of metrics.** Google's own MCP server gives agents direct access to Google Ads reporting. Lemon AI provides another route: connect Google Ads alongside your other networks, then use one MCP to query creative performance and the attributes attached to each asset. Copying a report into chat still works for a one-off investigation. The difficulty comes on the next question: a new date range, a different country, or the creative behind a row. A connected assistant can fetch that evidence instead of asking you for another export. ## Choose direct Google reporting or a unified creative view | Route | Best fit | What you still need to manage | | -------------------------- | --------------------------------------------------------------------- | ------------------------------------------------------------------------- | | Upload a Google Ads export | A bounded question about a saved report | Refreshing the file, preserving filters, and identifying the report grain | | Google's MCP server | Google-specific questions using its API resources and GAQL | Google Cloud access, authentication, and the server's deployment | | Lemon AI MCP and API | Recurring asset and attribute analysis across your connected networks | Connecting the right accounts and choosing comparable metrics | [Google's MCP documentation](https://developers.google.com/google-ads/api/docs/developer-toolkit/mcp-server) describes account discovery, resource metadata, and GAQL reporting. Its documented release is read-only. Use that route when your question needs a Google-specific resource; do not assume Lemon exposes every Google Ads API field. For the direct route, configure the Google Cloud project and credentials required by Google's current guide, connect the server to your MCP client, and first list accessible customers. A locally running server and a remotely hosted server have different setup paths. ChatGPT's web connection needs a supported remote connection, not a local command pasted into its Server URL field. ## Connect Google Ads to Lemon 1. Sign in to Lemon and open **Connections**. 2. Choose **Google Ads**, complete Google's authorization, and select the accounts you want to analyze. Use the Google identity that can access the intended account. 3. Allow the initial sync to finish. Open Creative Analytics and confirm that the campaign and dates you intend to query contain data. 4. Open **API & MCP** and use the server URL below to connect your assistant. Network authorization and assistant authorization are separate steps. Lemon organizes the synced data into creative-level reporting and makes assigned creative attributes available to the agent. That lets a follow-up move from “which video?” to “which hook or format?” without assembling another spreadsheet. See [how attribute analysis works](https://lemon-ai.com/attribute-analysis). ## Add Lemon to Claude or ChatGPT Use the same remote MCP server for all the networks you connect in Lemon: ```text https://api.lemon-ai.com/mcp ``` In **Claude**, open **Customize → Connectors → + Add → Add custom connector**. Enter a name and the URL, continue, and sign in to Lemon. If Claude asks how to register the OAuth client, choose **Register automatically**. Enable the connector in the conversation. Organization-managed accounts may need an owner to add it first. See the [Claude setup instructions](https://support.claude.com/en/articles/11175166-get-started-with-custom-connectors-using-remote-mcp). In **ChatGPT**, open **Plugins**, choose **Add custom MCP server**, and enter the URL. Select **OAuth** authentication, authorize Lemon, and install the resulting personal plugin. Mention it in a Work chat to use its tools. Availability depends on your workspace settings; follow the [current ChatGPT MCP instructions](https://developers.openai.com/api/docs/guides/custom-mcp-server) if the interface differs. Start by asking the assistant to call `list_ad_accounts` and let you select the intended account. Then use `list_filter_values` to discover dates and filters. Your ad-network sign-in connects data to Lemon; this second authorization lets the AI app read it. Do not paste network credentials into chat. ## Ask for an asset comparison with a defined scope Start with delivery and add outcomes only after discovering the available windows: > Use Lemon AI to list my Google Ads accounts and available date ranges. Let me choose the account and App campaign. For two complete weeks, return each video asset's impressions, clicks, cost, and CTR. Show the exact dates and filters. Flag truncated results and missing fields before interpreting the ranking. The relevant tool sequence is `list_ad_accounts`, `list_filter_values`, then `query_creative_performance`. The account ID comes from discovery; it is not the Google customer ID copied out of Ads Manager. The worked [MCP creative-performance workflow](https://lemon-ai.com/resources/mcp-creative-performance-workflow) shows the request structure. For a cross-network question, keep the account scopes separate initially. “Google versus Meta” can otherwise hide different countries, operating systems, creative formats, or attribution bases under one summary. ## Know what an allocated asset outcome means A Google ad can contain several assets. Lemon allocates Google conversion-lag outcomes from matched ad totals to assets. An allocated value is useful for inspection, but it is not a separate conversion event observed on that asset. **Synthetic illustration, not customer data or an API response:** suppose one matched ad has $400 in conversion value for a particular lag window. Its eligible assets receive the following allocation: | Fictional asset | Synthetic allocated value | Share of the matched ad value | | ---------------- | ------------------------- | ----------------------------- | | Puzzle reveal | $300 | 75% | | End card | $100 | 25% | | Matched ad total | $400 | 100% | The sum preserves the matched ad's $400 in this synthetic example. It does not establish that removing the end card would reduce revenue by $100\. The two elements may have appeared together, and allocation is not a randomized test of each element's contribution. Lemon's Google outcome suffixes describe conversion lag, such as `lag_lt_8d`. Do not rename that window “D7 post-install ROAS.” Discover the suffix and inspect maturity before comparing it with another provider. The [attribution-window guide](https://lemon-ai.com/resources/ad-network-attribution-windows) explains why the clocks matter. ## Turn the comparison into a creative question Two useful follow-ups keep the evidence attached to the answer: > For the same Google account, dates, and video population, list the available creative attributes. Use attribute\_insights to investigate CTR by hook. Show coverage, qualified creative counts, uncertainty, and creative examples. Describe an association, not a proven cause. > Recheck the apparent winning hook within the same campaign and country. Does the difference persist, or did a change in delivery mix explain it? Propose one controlled creative test and state what result would contradict the recommendation. An attribute must exist and have sufficient coverage before it can answer the question. The model should not infer a hook from a filename and present that guess as a stored label. ## Use the same reporting layer through the API For a script or another AI app, create a Lemon API key in **API & MCP**. Retrieve your account IDs with `GET /v1/ad-accounts`, then make a scoped read. This example uses a placeholder account and dates; substitute values returned for your account. ```bash curl --get 'https://api.lemon-ai.com/v1/creatives/performance' \ --header "Authorization: Bearer $LEMON_API_KEY" \ --data-urlencode 'ad_network_account_id=YOUR_ACCOUNT_ID' \ --data-urlencode 'date_from=2026-10-01' \ --data-urlencode 'date_to=2026-10-07' \ --data-urlencode 'metric=impressions' \ --data-urlencode 'metric=clicks' \ --data-urlencode 'metric=cost' \ --data-urlencode 'sort_by=cost' \ --data-urlencode 'sort_order=descending' \ --data-urlencode 'limit=25' ``` MCP and REST expose Lemon's reporting definitions. Inspect missing fields, result limits, and any outcome metadata before interpreting a result. A limited top-creatives response is not an account total. Use the [API documentation](https://api.lemon-ai.com/docs) for supported fields and pagination. ## When the result does not match Google Ads First align account, dates, timezone, currency, campaign, and reporting grain. Compare the same outcome definition rather than a platform-wide “Conversions” total with an allocated asset window. A recently completed sync can still contain an immature conversion window. If the account is absent, check the Google identity used for authorization and account selection in Lemon. If the account exists but the chosen campaign is absent, discover available filters before changing the query. If the response is truncated, narrow it before declaring an overall winner. For a repeatable starting point, [connect your ad accounts](https://app.lemon-ai.com/signup), then use the [reporting API and MCP overview](https://lemon-ai.com/reports) to choose the interface your team needs.
