Mobile Growth

npm

MCP server for mobile growth & user acquisition. Connects your LLM to a curated knowledge base of ad optimization insights and a library of analytical skills (campaign audits, fatigue detection, weekly diagnostics). Focused on subscription apps.

For Meta Ads data, use Meta's official Meta Ads MCP / AI connector. The skills here interpret what it returns. This MCP intentionally does not ship Meta API tools — keeping users on the official path.

For Google Ads, this MCP includes direct API integration (your tokens stay on your machine).

Quick Start

Claude Desktop

1. Open the config file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add this to the file (create it if it doesn't exist):

{
  "mcpServers": {
    "mobile-growth": {
      "command": "npx",
      "args": ["-y", "mobile-growth-mcp"],
      "env": {
        "API_KEY": "me_YOUR_KEY"
      }
    }
  }
}

3. Replace me_YOUR_KEY with the API key from your account admin.
4. Restart Claude Desktop.
5. To analyze Meta data, also install Meta's official Meta Ads MCP — its connector data flows through your LLM into the skills here.

Note: Use the JSON config file, not the "Add custom connector" UI in Claude Desktop. That UI is for remote servers — this MCP runs locally.

Other clients

Client	Config file
Claude Code	.mcp.json in your project root
Cursor	.cursor/mcp.json
Codex	MCP config in your Codex setup

Same JSON format as above.

Alternative: CLI args

{
  "mcpServers": {
    "mobile-growth": {
      "command": "npx",
      "args": ["-y", "mobile-growth-mcp", "--api-key=me_YOUR_KEY"]
    }
  }
}

No API key?

The server still starts — you get the Google Ads tools (if configured) and a connection_status tool that explains what's missing and how to fix it.

How It Works

The MCP server runs as a local process on your machine, started by your MCP client (Claude Desktop, Cursor, etc.).

• Knowledge base (remote) — curated expert insights hosted on our server, accessed via your API key
• Google Ads API (local) — calls happen directly from your machine using your tokens
• Meta Ads data — sourced from Meta's official AI connector, not from this MCP

Your ad platform tokens are used locally and are never sent to our servers.

What You Get

Knowledge base tools — search, browse, and retrieve expert insights on creative strategy, audience targeting, scaling, bid optimization, and more.

Google Ads API tools — pull campaigns, ad groups, assets, performance insights, and network mix directly from your Google Ads account.

Analytical skills (MCP prompts) — KB-grounded methodologies for ad fatigue, weekly performance, creative health, placement audits, audience composition, architecture reviews, campaign comparisons, attribution analysis, and full account audits. The Meta-flavored skills consume data from Meta's official AI connector or pasted CSVs.

Tools

Report Prompts (Skills)

Each Meta-flavored prompt takes an ad_account_id and walks the LLM through a structured analysis. Data comes from Meta's official AI connector or pasted CSV exports.

Prompt	Description
ad-fatigue-report	Detect creative fatigue with daily granularity
weekly-performance	Week-over-week health with Kast diagnostic framework
creative-performance	Categorize ads: scaling / promising / fatiguing / dead weight
audience-composition	Age × gender heatmap with CPA analysis
architecture-review	Campaign structure evaluation
audit-meta-account	Comprehensive account audit
campaign-comparison	Side-by-side campaign comparison
placement-audit	Detailed placement audit with waste quantification
attribution-analysis	Conversion quality validation
google-campaign-health	Google App Campaign WoW health check
google-asset-performance	Google asset categorization by actual CPI
google-network-audit	Search/Display/YouTube spend analysis
google-architecture-review	Google App Campaign structure audit
google-bid-strategy	Google bid strategy + signal volume evaluation

All reports reference specific knowledge base insight IDs so recommendations are grounded in expert knowledge, not generic advice.
