To use MCP for marketing, add an MCP server for your ad platform to Claude or ChatGPT, sign in to approve access, then ask questions about spend, campaigns and search terms in plain English. MCP (Model Context Protocol) is the open standard that lets an AI app talk to your tools.

## What MCP is

The MCP site calls it an open standard for connecting AI apps to outside systems, and compares it to a USB-C port: one plug that fits many tools ([modelcontextprotocol.io](https://modelcontextprotocol.io/introduction), checked 2026-10-20). Without it, you copy numbers out of Ads Manager and paste them into a chat. With it, the AI asks the platform directly. See [what MCP is](/glossary/mcp) and [what an MCP server is](/glossary/mcp-server).

## What marketers use it for

| Use | Example question |
|---|---|
| Reporting | "Spend and cost per purchase by campaign, this week against last week" |
| Search terms | "Which Google search terms spent the most and never converted?" |
| Account checks | "Which ad sets have been in Learning limited for two weeks?" |
| Creative review | "Which ads are showing signs of fatigue?" |
| Changes | "Draft a new ad set and wait for my approval" |

## Who runs the servers

- **Meta** hosts its own ads MCP server. Its documentation lists reporting, building and editing ads, catalogs, signal health, A/B tests and activity logs ([Meta](https://developers.facebook.com/documentation/ads-commerce/ads-ai-connectors/ads-mcp-server/ads-mcp-server-overview), checked 2026-10-20).
- **Google** publishes an open-source Google Ads server with three tools: search, get resource metadata and list accessible customers. You run it yourself, and it needs Python and Google credentials ([GitHub](https://github.com/googleads/google-ads-mcp), checked 2026-10-20).
- **Hosted vendors** run the server for you. You add one address to your AI app and sign in. See the [best MCP servers for marketing](/best/best-mcp-servers-for-marketing).

## A safe first week

1. Pick one question you ask every Monday.
2. Connect with read-only access. Do not allow changes yet.
3. Ask the question and open Ads Manager to check the numbers once.
4. If they match, add a second question.
5. Allow changes only for work you would approve by hand, such as drafts.

## A worked example

Say you ask: "Spend by campaign, this week against last week." The AI answers that your Diwali sale campaign spent INR 51,000 against INR 42,000. That is INR 9,000 more, and 9,000 / 42,000 is about 21%. You ask a follow-up: "Did cost per purchase rise too?" If it did, you check the ad set yourself before you cut budget.

## Mistakes to avoid

- Allowing edits on day one
- Trusting a number you never checked against the platform
- Connecting a server you do not know
- Mixing two clients' accounts in one chat, if you are an agency

We make Marxx. Its hosted [MCP server](/mcp) puts your Meta and Google Ads accounts inside Claude and ChatGPT.

## FAQ

### Do I need to code to use MCP?

No, if you use a hosted server. In Claude you add it as a custom connector: paste its address, then sign in ([Claude Help Center](https://support.claude.com/en/articles/11175166-get-started-with-custom-connectors-using-remote-mcp), checked 2026-10-20). Running Google's open-source server yourself does need Python.

### Does MCP work with both Claude and ChatGPT?

Yes. The MCP site names both as supported AI assistants (checked 2026-10-20). Plans and menus differ, so check each app's connector settings.

### Can an AI change my ads through MCP?

It depends on the server and the rights you grant. Meta's server can build and edit ads, so limit it to reading first.
