What it does

Synter is an AI agent media buyer exposed as one MCP server for advertising. You connect your ad accounts once, then ask Claude, Cursor, ChatGPT or Synter's own Campaign IDE to pull reports, build plans, ads and audiences, launch campaigns and optimise budgets across search, social, retail-media and programmatic platforms. Agents execute in your accounts through spend limits, approval gates and an audit trail, and the autonomy level is yours to set.

Features

  • One MCP for many ad platforms. Connect ad accounts once and run campaigns, creative, audiences, tracking and optimisation from one MCP; capabilities vary by platform and account. Official source 1 ↗
  • Agents that execute with approvals. Agents write directly in your ad accounts through spend limits, approval gates and an audit trail; in conservative mode every write needs approval. Official source 1 ↗
  • Chat with your ad data. Ask which campaigns to scale, why CPA moved or what to pause, and get answers from connected accounts with a recommended next action. Official source 1 ↗
  • Brief to campaign. Describe what you need to launch and the agents build the plan, ads and audiences for review. Official source 1 ↗
  • Creative Studio. A canvas editor with artboards and layers for designing ads and shipping them to each platform. Official source 1 ↗
  • Autopilot on Scale. Scale adds 24/7 autonomous ROAS optimisation and one-click bulk execution; Solo uses manual one-by-one reviews. Official source 1 ↗
