Synter is an AI-powered advertising platform that lets AI agents build, launch and optimise ad campaigns across 43 advertising platforms from one connection. It describes itself as a universal MCP (Model Context Protocol) server for advertising with agents, acting as an AI agent media buyer.
Teams connect their ad accounts once, then run campaigns, creative, audiences, signals, tracking and optimisation from agents such as Claude, Cursor or ChatGPT. Synter prepares reviewable drafts and holds campaigns until a person approves them.
Every change passes through safety gates and guardrails, so consequential changes need approval before they go live. Teams set the guardrails and approve what the agents do.
Key features include full MCP, CLI and API access, AI agents for campaigns, creative, audiences and measurement, a Campaign IDE, cross-platform reporting and attribution, and 24/7 autonomous ROAS optimisation (Autopilot) with one-click bulk execution on higher plans.
Supported ad platforms include Google, Meta, LinkedIn, TikTok, Reddit, X and Microsoft, plus programmatic channels. It also connects to CRMs such as HubSpot, Salesforce, Attio and Pipedrive.
Pricing: the Solo Developer plan is $20 per month and includes $20 in claimable usage credits, or $200 per year. The Scale plan is $500 per month with $500 in usage credits, five seats and Autopilot, or $5,000 per year. Custom plans are available through a workshop, and extra workspaces cost $500 per month each. A card is required at checkout.
Synter also offers resources such as a manual, developer docs, free ad audits and use-case briefs for growth teams and agencies.
It is suited to growth teams, agencies, performance marketers and developers who want their AI agents to manage paid advertising across many platforms with human approval built in.
