Setup

Three ways to connect

Add the server URL to your client. On first use it registers itself and opens the AdStellar consent screen, where you pick the team and scopes.
2
Your own agents: use an API key
Create a team-scoped key in Settings > Developers and send it as a bearer token. Give the key only the scopes the agent needs.
3
Or call it over REST
Every MCP tool is also a REST endpoint with the same credential, described by an OpenAPI spec.

Examples

What to ask over MCP

Plain language is enough. AdStellar picks the right tool, answers from your account, and asks before it changes anything.

Generate a 9:16 image ad for my product, 2 variations.
How did my campaigns perform over the last 7 days, grouped by campaign?
Pause every ad set with a CPA over $40 this week, and show me the list first.
Build a sales campaign for my main product at $50/day and walk me through the preview before launching.
Whenever a campaign spends $50 with a CPA above $40 over 7 days, suggest pausing it.
