Meta Ad Library Monitor MCP Server

An MCP server that finds a company's active Facebook and Instagram ads through the Meta Ad Library API. It wraps the Mamba Labs Meta Ad Library Monitor actor on Apify and returns Clay-ready flat JSON rows to any MCP client.

What it does

Give it a company name or domain and your own Meta access token, and it searches the Meta Ad Library and returns one flat row per ad: creative text, headline, delivery dates, the Meta surfaces the ad ran on, and Meta's permanent snapshot URL for the rendered ad.

Read the coverage first, because it decides whether this tool is any use to you. It reads Meta's Ad Library Graph API, which is the only route Meta sanctions, and that API publishes two things: every ad delivered to an audience in the EU, whatever the ad is about, and social issue, election and politics ads worldwide. So an EU heavy list gets good coverage of ordinary commercial advertising, while a US or UK list of ordinary product ads mostly comes back not_found. That is Meta's dataset rather than a fault in the lookup, and every row carries a coverage note saying what the search could have found. Impressions and spend exist for political ads only and arrive as bands, so a null there is not zero spend.

All of the searching runs on Apify. This package is a thin client that calls the actor and hands back the result unchanged.

Quick start

You need Node.js 18 or newer and an Apify account with an API token.

Add this to your Claude Desktop config:

{
  "mcpServers": {
    "mamba-meta-ad-library-monitor": {
      "command": "npx",
      "args": ["-y", "@mambalabsdev/mcp-meta-ad-library-monitor"],
      "env": {
        "APIFY_TOKEN": "your-apify-token"
      }
    }
  }
}

Get your token at https://console.apify.com/account/integrations, paste it in, and restart Claude Desktop. The find_meta_ads tool will be available.

You also need your own Meta app access token, free to create at developers.facebook.com. Set it as META_ACCESS_TOKEN in the same env block to keep it out of the chat transcript, or pass it per call as the metaAccessToken tool argument. With neither, the tool returns an error before any Apify run starts, so a missing token costs nothing.

Prerequisites

• Node.js 18 or newer
• An Apify account with an API token
• Your own Meta app access token, free at developers.facebook.com. The Ad Library API is not open, so this is required.
• A verified identity on your Meta account if you want political and issue ad data. That is Meta's requirement, not ours.

Example prompts

• "Is gymshark.com running Facebook ads in the EU right now? Here is my Meta token."
• "Show me the last 25 active ads for this company across EU audiences."
• "Find video ads only for this advertiser, active and inactive."
• "Search the Meta Ad Library for this brand in the UK and tell me what the coverage note says."

Inputs

• company_domain (optional): bare company domain, for example gymshark.com. Used to derive the advertiser search term when no company name is given, and used by the identity gate to check that a matched advertiser page really is this company.
• company_name (optional but strongly recommended): Meta advertiser search is a fuzzy text search over page names, so the company name is what the identity gate compares a matched page against. Without it the gate falls back to the domain stem, which is weaker.
• metaAccessToken (required unless META_ACCESS_TOKEN is set in the server environment): your own Meta app access token, free to create at developers.facebook.com. The Ad Library API is not open, so a call with neither returns an error and starts no run.
• ad_reached_countries (optional): which country audiences to search. One of EU, GB, US, DE, FR, NL, ES, IT, IE or ALL_EU_PLUS_UK. Meta requires this parameter and a request without it fails outright. The EU set is where the Ad Library covers all ads rather than only political ones, so it is the default.
• ad_active_status (optional): ACTIVE, ALL or INACTIVE. ACTIVE is the default because a currently running ad is the buying signal. ALL is what you want for a creative history or a competitive teardown.
• ad_type (optional): ALL returns every ad the Ad Library holds for those countries. POLITICAL_AND_ISSUE_ADS narrows to the political archive, which is the only archive carrying impressions and spend and which requires a verified identity on your Meta account.
• media_type (optional): ALL, IMAGE, VIDEO, MEME or NONE. Useful for a creative teardown where you only care about video.
• maxAds (optional): how many ad rows to return per company. One of 10, 25, 50 or 100. This is a cost dial, not a change of answer: the row always reports how many ads matched before the cap.
• skipCache (optional): when false (the default) a successful lookup is cached for seven days and reused. Set true to force a fresh fetch.
• max_charge_usd (optional): spending cap for this call, in USD. The actor stops before any charge that would take the run past this amount and keeps every row already charged.

Output

The tool returns the actor's flat JSON rows, one per ad, in snake_case with no nested objects. advertiser_match says how the advertiser page was matched and advertisers_rejected counts the ones the identity gate turned away. coverage_note states what the search could have found, so an empty result is readable. impressions and spend are populated for political and issue ads only. See the Apify Store page for the full output schema.

Features

• One flat row per ad, with creative text, headline and delivery dates
• Meta's own permanent snapshot URL for each rendered ad
• The Meta surfaces an ad ran on, in publisher_platforms
• Reads Meta's sanctioned Ad Library Graph API and no other route
• A coverage note on every row, so an empty result is readable
• Advertiser identity gate, with rejected candidates counted

Pricing

You pay per event on Apify, billed to your own Apify account. Prices from the live pricing record, read 2026-10-16:

Event	Price per event (USD)	Fires when
apify-actor-start	$0.00005	Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
advertiser-checked	$0.004 on the Free plan, down to $0.0028 on higher Apify plans	Once per company for which the Ad Library was searched and a non degraded result was produced, whether or not any ads were found. An advertiser with no ads fires this once and nothing else, because looking and finding nothing is a real answer and it is the work you asked for. A degraded row, where no search ran, fires nothing.
ad-returned	$0.002 on the Free plan, down to $0.0014 on higher Apify plans	Once per ad row actually returned, after the identity gate. Ads belonging to a page that failed the gate are not returned and are not charged: the work was done and the honest answer is that those ads are not this company.

The actor's Apify page carries the current prices. Running this server consumes Apify credits.
