How to Connect Bing Webmaster to ChatGPT?

Before you start

You'll need a SourcetoMCP account with at least one brand created, a Bing Webmaster Tools account with at least one verified site, and a ChatGPT account on a Pro, Plus, Business, Enterprise or Education plan. Custom MCP connectors run through developer mode, which works on ChatGPT on the web only.

Generate an API key in Bing Webmaster Tools

1. 1Sign in at bing.com/webmasters with the Microsoft account tied to your site.
2. 2Make sure the site you want to connect is already added and verified.
3. 3Click your profile icon (top right) → Settings → API Access.
4. 4Select Generate API Key, then copy it immediately, because Bing only shows the full key once.

One key covers every site your account can see, and you'll pick which sites to connect in the next step.

Connect Bing Webmaster Tools to SourcetoMCP

1. 1From your dashboard, go to Connectors → Add a connection.
2. 2Find the Bing Webmaster Tools card and select Connect.
3. 3Paste the API key into the field and select Connect Bing Webmaster Tools. This verifies the key directly against Bing.
4. 4Choose which verified site(s) to connect, then confirm.

Connected sites then appear on your Connections page like any other source.

Add SourcetoMCP as a connector in ChatGPT

1. 1In SourcetoMCP, open Connect an agent from the dashboard sidebar and copy your server address (it looks like https://sourcetomcp.com/api/mcp).
2. 2In ChatGPT, open Settings, then Security and login, and turn on Developer mode. Custom MCP connectors sit behind this toggle, and it only appears on ChatGPT on the web.
3. 3Open the Plugins menu and select the “+” button to create a developer-mode app.
4. 4Enter the name SourcetoMCP, paste in your server address, and pick OAuth as the authentication type.
5. 5Save. The app now sits under Drafts in your app settings, where you can switch individual tools on or off.
6. 6The first time ChatGPT calls it, you'll be asked to sign in to SourcetoMCP and approve access, the same OAuth approval you'd see connecting any other app. After that it reconnects on its own.

Once approved, the connection appears under Active connections on the Connect an agent page in SourcetoMCP, so you can see exactly what has access at any time.

Ask ChatGPT about your Bing Webmaster Tools site

A developer-mode app stays off until you pick it. In a chat, open the Plus menu, choose Developer mode, and select SourcetoMCP for that conversation. Naming the app in your question helps ChatGPT reach for the right tool, as in “Use the SourcetoMCP app to get my top queries last month”.

Anything that writes back to a connected account asks you to confirm first, and ChatGPT shows you the JSON payload it plans to send. Read it before you approve.

With both pieces connected, ChatGPT can query your Bing search performance, check crawl health, research keywords using Bing's own search data, and look at who links to your pages, and act on what it finds if you ask. Try something like:

1. 1What has my organic search performance on Bing looked like over the last month?
2. 2Are there any crawl issues Bing has flagged for my site?
3. 3Find keyword opportunities related to [topic] using Bing's own search data.
4. 4Check my sitemap's status, and resubmit it if it's failing.

The first three are read-only reports. The last one is a write action. See the note below on how SourcetoMCP handles those.

A note on write actions

Bing Webmaster Tools through SourcetoMCP can do two things beyond reporting: ask Bing to recrawl a URL (one at a time or in a batch), and submit or remove a sitemap. Neither changes anything on your actual site, and neither can affect spend or take content offline the way a write action on an ads connector can. The worst case is a wasted submission against Bing's own daily quota. ChatGPT will still tell you what it's about to do before it does it.

Troubleshooting

“That API key was rejected”: the key is wrong, was regenerated since you copied it, or was revoked. Generate a fresh one under Settings → API Access and try again.

My site isn't in the list when connecting: the account the key belongs to hasn't added or verified that site in Bing Webmaster Tools yet. Add and verify it there first, then reconnect.

Developer mode is missing from Settings: it is available on Pro, Plus, Business, Enterprise and Education accounts, and only on ChatGPT on the web. The mobile apps do not show it.

The app never appears in a chat: developer-mode apps sit under Drafts and stay off until you pick them. Open the Plus menu, choose Developer mode, and tick SourcetoMCP for that conversation.

ChatGPT says it can't find the tool or has no data: open the app's details page and use Refresh to pull the current tool list from the server. If that changes nothing, check the connection still shows under Active connections in SourcetoMCP.

Revoking access

You can disconnect from either side. In SourcetoMCP, remove the site from your Connections page, or revoke ChatGPT's access entirely from the Connect an agent page. In ChatGPT, open your app settings, find SourcetoMCP under Drafts, and delete it. In Bing Webmaster Tools, generate a new API key under Settings → API Access, which invalidates the old one.
