01
What GoMarble offers
GoMarble describes AI agents that watch every account, explain what changed and queue the next move, across Meta, Google, TikTok, Microsoft Ads, GA4, Shopify, Klaviyo and more than 80 connectors. Approvals happen in its app and in Slack.
Its MCP server brings GoMarble into Claude, ChatGPT, Cursor, Claude Code, n8n and other clients, with OAuth or an API key. MCP is included in every plan: read-only on Copilot, with write actions from Operator.
02
Both ask before changing an account
GoMarble states that nothing changes until you say yes, and shows the reason, the exact edit and the expected effect. Approval policies and role-based access come with its Scale plan.
Adrails works the same way for every change an agent or an AI client prepares: the proposal names the account, the entity and the before and after, and applies only after an owner or admin approves it. Approval reads the platform again and blocks the change if the entity moved in the meantime.
03
Pricing and fit
GoMarble's free plan includes one read-only agent and 100 one-time credits. Copilot is $139 a month for 5 ad accounts and up to $50K of monthly spend, read-only. Operator, at $399 a month, adds write actions for 15 ad accounts and up to $500K of spend, and Scale is $799 for 40 accounts.
Adrails plans start at $149 a month with unlimited ad accounts and no spend tier, and an MCP tool call uses no agent credit. Choose GoMarble for wider platform and connector coverage; choose Adrails for Meta and Google work across many accounts at a fixed price.
