Example question
What did we spend on each platform last week?
Marketing and advertising · MCP connector
Ask Claude or ChatGPT about your ad spend, across every platform.
Meta, Google, Microsoft, Taboola and more, in one conversation. Junction reads your numbers and can never change them: no paused campaigns, no budget changes, no spend. One connector instead of a separate MCP server for every platform.
MCP gateway
Never writes
It cannot edit, pause, spend or post. It only reads.
Per-person access
Each person sees only the systems, data and rows an admin allows.
Sensitive data hidden
Payroll and personal fields are denied by default.
Audit log
Who asked what, and whether it worked. Never the values.
01 · What you can ask
Answers your team now waits for an export to get.
Agencies
- “Give me spend, clicks and conversions for each client account this month.”
- “Which accounts are pacing over or under budget?”
- “Where did the biggest week-on-week change come from?”
Finance and leadership
- “What is our total ad spend this quarter, by platform?”
- “Which platform has the highest cost per acquisition?”
- “How does this month's spend compare with the same month last year?”

04 · Why Junction
Built for people who answer for the budget.
- It can never spend your money
- No paused campaigns, no budget or bid changes, no published ads. Some platform connectors can edit your account; Junction only reads.
- One connector, every platform
- One address and one sign-in for all your platforms, instead of a separate MCP server for each, so one question can compare them side by side.
- Each person sees only their accounts
- Give an agency client, a regional team or a finance analyst access to just the accounts they should see. Access can only be narrowed, never widened.
- One definition of every metric
- Questions are built from a signed data model, so spend, clicks and conversions mean the same thing on every platform, not whatever the AI guessed.

05 · Questions
Frequently asked questions
Is there an MCP server for Meta Ads, Google Ads, Microsoft Advertising or Taboola?
Several of these vendors publish their own MCP server, and others have only an API. Each vendor's server covers that one platform, with its own sign-in, and some can also create or change campaigns. Junction's aim is one connector that covers all of your platforms, including those with no MCP server of their own, so one question can span them, and access that can only read. Request early access and tell us which platforms you run.
What could I ask once it is connected?
Questions about performance that today need an export or a dashboard: spend by platform this month, which campaigns have a cost per conversion above target, how clicks and conversions compare across platforms, which ad groups stopped delivering. Every answer would come from your own ad accounts, with the platform and the time the data was read.
Can it change my campaigns, bids or budgets?
No. Junction only reads. It cannot create, pause, edit or delete a campaign, an ad or a budget, and we ask you to authorise it with the narrowest access that can read reports.
How does it sign in to my ad accounts?
Junction uses each platform's own authorisation, with your consent and the narrowest read access it offers, not a shared password. Credentials are stored sealed, never shown back and never passed to your AI tool, and you can remove a connection at any time.
Do you run the AI model, and does it cost extra?
We do not run any AI model. You use your own Claude or ChatGPT subscription. Junction only supplies the data when the assistant asks for it.
Which platforms are first?
Meta Ads, Google Ads, Microsoft Advertising and Taboola lead the list, with LinkedIn, TikTok, Pinterest, Snapchat, Outbrain and Google Analytics 4 alongside them. Name yours in the request form and we set it up with you.
