Connecting Pinterest Ads to Claude

Before you start

You'll need a SourcetoMCP account with at least one brand created, a Pinterest account with access to at least one ad account, and a Claude plan that supports custom connectors.

1. Connect Pinterest Ads to SourcetoMCP

1. 1From your dashboard, go to Connectors → Add a connection.
2. 2Find the Pinterest Ads card and select Connect.
3. 3Sign in with the Pinterest account that has access to the ad account you want. This opens Pinterest's own consent screen, not a SourcetoMCP form, and asks you to approve access to your ad performance data plus your boards and pins — SourcetoMCP can read and manage both, not just run reports.
4. 4Back in SourcetoMCP, choose which ad account(s) to connect, then confirm. They show up on your Connections page.

2. Add SourcetoMCP as a connector in Claude

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 Claude, open Settings, then Connectors (Custom Connectors if you're on the beta).
3. 3Select Add connector, then paste in your server address.
4. 4The first time Claude uses 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 automatically.

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.

3. Ask Claude about your Pinterest account

With both pieces connected, Claude can query campaign, ad group and creative performance, break down conversions by funnel step, and separately report on your boards and pins' organic reach — and, if you ask, act on either side. Try something like:

1. 1How did my campaigns perform this week compared to last?
2. 2Break down my conversions by funnel step for this month.
3. 3Which of my boards are getting the most engagement right now?
4. 4Reallocate budget from my weakest campaigns into my strongest ones.

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

Unlike a read-only connector, Pinterest Ads through SourcetoMCP can create and change real things — campaigns, boards and pins, on both the ad and organic side. New campaigns are created paused by default, so nothing starts spending without an explicit follow-up action. Board and pin deletion is real too, not reversible from inside SourcetoMCP, so it's worth reading what Claude proposes before confirming anything it describes as removing or replacing content, the same as you would for any assistant with write access to a live account.

Troubleshooting

My ad account isn't in the list when connecting: the signed-in Pinterest account doesn't have access to that ad account. Add it under Pinterest's own Business Access settings, then reconnect.

Claude doesn't show a Connectors option: custom connectors currently roll out by plan; check your Claude plan or the Custom Connectors beta if you don't see it.

Claude says it can't find the tool or has no data: reopen the connector in Claude's Settings and confirm it still shows as connected; if not, remove and re-add it to trigger a fresh approval.

Revoking access

You can disconnect from either side. In SourcetoMCP, remove the account from your Connections page, or revoke Claude's access entirely from the Connect an agent page. In Claude, remove the connector from Settings → Connectors.
