AI Media Buyer

A senior AI media buyer in your terminal.
Built by GoMarble.

A senior AI media buyer at your fingertips. Meta strategists, Google Ads specialists, creative-fatigue analysts, GA4 attribution experts, Shopify ops leads — each a specialized agent with battle-tested processes, not a generic chatbot.

AI Media Buyer is the AI media buyer for Claude Code & Codex CLI — it plugs your terminal into your ad accounts and turns it into a senior media buyer across Google Ads, Meta, TikTok, LinkedIn, Bing, GA4, Shopify, Klaviyo & Search Console. Built by GoMarble, the team that runs paid media for some of the fastest-growing DTC brands.

• 🔌 Live ad-platform data via the GoMarble MCP server — OAuth, one-click sign-in
• 🧠 36 expert-authored skills — Google Ads, Meta (Facebook/Instagram), GA4, Shopify, Search Console, Klaviyo, TikTok, LinkedIn, Bing Ads, document generation
• ⚡ 8 morning-workflow slash commands — daily audits and decision matrices for Meta + Google
• 🛡️ Built-in guardrails — no synthetic data, no fabricated keywords, proper attribution discipline

Install

Claude Code

In a Claude Code session, paste these three commands:

/plugin marketplace add https://github.com/gomarble-ai/ai-media-buyer.git
/plugin install ai-media-buyer@ai-media-buyer
/reload-plugins

Using the full HTTPS URL (not the owner/repo shorthand) avoids SSH-key errors on machines where git is configured to rewrite GitHub HTTPS URLs to SSH.

Then connect the MCP server:

/mcp

Pick gomarble, click Authenticate — the browser opens, you sign in to GoMarble, you're done.

Codex CLI

codex plugin marketplace add https://github.com/gomarble-ai/ai-media-buyer.git

Start Codex, open the Plugins panel, find AI Media Buyer, and install. Then:

codex mcp login gomarble

Same OAuth flow, one-time.

One-command install for both (via npm)

npx ai-media-buyer

This wraps the official commands above and works on macOS / Linux / Windows.

🗣️ What you can ask the agent

The skills auto-invoke based on what you ask — you don't have to remember anything. Some examples:

Ask	What happens
"Audit my Meta account act_12345 for the last 30 days."	Loads performance + creative + depth-of-analysis skills, pulls 30d data, runs Pareto analysis, flags fatiguing creatives, surfaces ROAS outliers, produces a report.
"How did my Google Ads Search campaigns do this week?"	Loads search-analysis skill, classifies queries Q1–Q5, diagnoses CPC inflation or rank pressure, returns a decision matrix.
"Create a Meta ad set for this creative targeting US iOS users."	Loads create/master + adset skills, verifies parent campaign, detects pixel, builds the propose payload, asks you to confirm before posting.
"Pull a 7d Shopify sales report and compare to GA4 conversions."	Loads Shopify order-discipline + GA4 source-of-truth skills, queries both, reconciles the difference.
"Generate a PPTX summarizing all my paid-media performance."	Loads pptx skill + the relevant analytics skills, produces a deck.

⚡ Slash commands (Claude Code only)

8 read-only morning-workflow commands. Each produces analysis + recommendations — never executes mutations. Mutations happen separately via Agent Mode if the user explicitly opts in. Click any command name to view its source.

🔄 How it works

You ask:  "Audit my Meta account"
    ↓
Claude / Codex auto-invokes the right skills by description
    ↓
Skill instructs the agent to call GoMarble MCP tools (meta_get_account_insights, etc.)
    ↓
GoMarble MCP → live Meta Ads API call (with your OAuth token)
    ↓
Agent applies the methodology + guardrails to interpret the data
    ↓
You get the answer

The plugin ships only the methodology. All live data comes from the GoMarble MCP server you authorized with /mcp (Claude) or codex mcp login gomarble.

🔁 Updating

# Claude Code
/plugin marketplace update ai-media-buyer

# Codex CLI
codex plugin marketplace update ai-media-buyer

The SessionStart hook also surfaces an "update available" prompt automatically the first time you start a session on an outdated version.

📁 Repo layout

This is what gets installed when you run any of the install commands above:

ai-media-buyer/
├── .claude-plugin/

├── skills/                      # 36 SKILL.md folders — both hosts read from here
└── README.md

Why one folder works for both hosts

Each host looks for its manifest in a dedicated subfolder; everything else is shared.

Host	Manifest	Reads	Ignores
Claude Code	.claude-plugin/plugin.json	skills/, commands/, .mcp.json (mcpServers key)	.codex-plugin/
Codex	.codex-plugin/plugin.json	skills/, .mcp.json (mcp_servers key)	.claude-plugin/plugin.json, commands/

.mcp.json ships both wrapper keys with identical content so each host finds its preferred form.
