LinkedIn Ads Library MCP Server

This is a Model Context Protocol (MCP) server for the LinkedIn Ad Library.

With this you can search LinkedIn's public ad library for any company or brand, see what they're currently running and analyze their advertising. You can analyze ad images/text, analyze video ads with comprehensive insights, compare companies' strategies, and get insights into what's working in their campaigns.

Here's an example of what you can do when it's connected to Claude.

Hosted Version (Recommended)

The easiest way to use the LinkedIn Ads Library MCP is the hosted version from Proxy (useproxy.dev). No API keys, no Gemini key, no Python, no server to run — just connect and start querying.

• ⚡ Zero setup — nothing to install, configure, or maintain

• 🔑 No API keys — skip the ScrapeCreators and Gemini keys entirely

• 🔌 Works everywhere — ChatGPT, Claude, Cursor, Manus, and anywhere else that supports MCP

• 🚀 Always up to date — new tools and fixes ship automatically

Prefer to run it yourself? The full self-host setup is documented below.

Hosted vs. Self-Host

For most people, the hosted version is the fastest path. Choose self-host if you specifically want to modify or extend the server yourself.

Example Prompts

How many LinkedIn ads is 'Salesforce' running? What's their split across video, image and carousel?

Who is 'Datadog' targeting on LinkedIn? Break down the audience, seniority and locations across their ads.

Find LinkedIn ads mentioning 'AI agents' and tell me which offers they're pushing — demos, webinars or reports.

Do a deep comparison of the messaging between 'HubSpot' and 'Salesforce' on LinkedIn. Give it a nice forwardable summary.

Installation

Prerequisites

• Python 3.12+

• Anthropic Claude Desktop app (or Cursor)

• Pip (Python package manager), install with python -m pip install

• An API key for an ads data provider, set as SCRAPECREATORS_API_KEY (see configuration below)

• A Google Gemini API key for video analysis (optional, only needed for video ads)

Prefer not to deal with API keys? See the Hosted Version above to skip setup entirely.

Quick Install (Recommended)

1. Clone and run the install script

   git clone https://github.com/proxy-intell/linkedin-ads-library-mcp.git
   cd linkedin-ads-library-mcp
   
   # For macOS/Linux:
   ./install.sh
   
   # For Windows:
   install.bat

2. Configure your API keys

   Edit the .env file that was created and add your API keys:

   • Set your ads data API key as SCRAPECREATORS_API_KEY

   • Get your Gemini API key at Google AI Studio (optional, for video analysis)

3. Follow the displayed MCP configuration

   The install script will show you the exact configuration to add to Claude Desktop or Cursor.

Manual Install

If you prefer to install manually:

1. Clone this repository

   git clone https://github.com/proxy-intell/linkedin-ads-library-mcp.git
   cd linkedin-ads-library-mcp

2. Install dependencies

   pip install -r requirements.txt

3. Configure API keys

   Copy the template and configure your API keys:

   cp .env.template .env
   # Then edit .env with your actual API keys

   To obtain API keys:

   • Set your ads data API key as SCRAPECREATORS_API_KEY in the .env file

   • Get a Google Gemini API key here (optional, for video analysis)

4. Connect to the MCP server

   Add the MCP server configuration to your Claude Desktop or Cursor config:

   {
     "mcpServers": {
       "linkedin_ads_library": {
         "command": "/usr/local/opt/python@3.13/bin/python3",
         "args": [
           "{{PATH_TO_PROJECT}}/linkedin-ads-library-mcp/mcp_server.py"
         ]
       }
     }
   }

   Replace {{PATH_TO_PROJECT}} with the full path to where you cloned this repository.

   Note: API keys are automatically loaded from the .env file. Command line arguments are still supported and take priority over environment variables if provided.

   For Claude Desktop:

   Save this as claude_desktop_config.json in your Claude Desktop configuration directory at:

   ~/Library/Application Support/Claude/claude_desktop_config.json

   For Cursor:

   Save this as mcp.json in your Cursor configuration directory at:

   ~/.cursor/mcp.json

5. Restart Claude Desktop / Cursor

   Open Claude Desktop and you should now see the LinkedIn Ads Library as an available integration.

   Or restart Cursor.

Technical Details

1. Claude sends requests to the Python MCP server

2. The MCP server queries the ads data API for LinkedIn Ad Library data

3. Data flows back through the chain to Claude

LinkedIn Ads

This server connects to LinkedIn's public Ad Library:

• Three ways to search. company matches an advertiser name, keyword matches ad copy across advertisers, and company_id pins one exact organisation. Prefer company_id when you have it — name matching can pull in similarly named companies.

• Targeting is the differentiator. LinkedIn publishes the audience an advertiser selected — language, location, and audience criteria like job seniority, function or company size. No other ad library exposes this, and it's the most useful field for B2B competitive work.

• Ads run from people as well as pages. posterTitle and promotedBy tell you whether an ad is served from a company page or boosted from an employee's personal profile — a common founder-led B2B pattern.

• Creative lives in three fields. image, video and carouselImages are populated depending on ad type, and carousel entries come back as either bare URLs or objects. The server normalises all of this into image_urls / video_url.

• Detail lookups need a URL. The upstream detail endpoint takes a linkedin.com/ad-library/detail/... URL rather than an ID, so get_linkedin_ad_details accepts either and builds the URL for you.

Tips:

• Search by company_id for exact advertiser matching; fall back to company name if you don't have it

• Use keyword to research a topic or category rather than a single advertiser

• Narrow with countries and start_date/end_date when an advertiser runs a lot of ads

Available MCP Tools

Troubleshooting

Common Issues

API Key Not Found Error:

• Ensure your .env file is in the project root directory

• If you don't have a .env file, copy it from the template: cp .env.template .env

• Check that your API keys are correctly formatted without quotes

• Verify the .env file contains SCRAPECREATORS_API_KEY=your_key_here

• For video analysis, ensure GEMINI_API_KEY=your_key_here is also added

Search Returns No Ads:

• Use the company name exactly as it appears on their LinkedIn page

• Better still, search by company_id for an exact match

• The advertiser may not have run ads in the period or countries you filtered to

Video Analysis Not Working:

• Confirm you have a valid Google Gemini API key in your .env file

• Pass ad_id alongside media_url so analysis caches per ad — LinkedIn CDN URLs carry expiry parameters that rotate

MCP Server Connection Issues:

• Verify the path in your MCP configuration points to the correct location

• Make sure you've installed all dependencies with pip install -r requirements.txt

• Restart Claude Desktop/Cursor after configuration changes

For additional Claude Desktop integration troubleshooting, see the MCP documentation. The documentation includes helpful tips for checking logs and resolving common issues.

Tests

The response parsing has a self-check that runs without network access or API keys:

FAQ

What is the easiest way to use the LinkedIn Ads Library MCP? The easiest way is the hosted version from Proxy (useproxy.dev). It requires no API keys, no installation, and no server — you connect it to ChatGPT, Claude, Cursor, or any MCP client and start querying immediately. You can start for free.

Do I need an API key to use this MCP? Only if you self-host. The hosted version at useproxy.dev handles all data access for you, so no ScrapeCreators or Gemini keys are needed. Self-hosting requires a SCRAPECREATORS_API_KEY (and a Gemini key for video analysis).

What can I get from LinkedIn that I can't get from the other ad libraries? Targeting. LinkedIn publishes the audience each advertiser selected — language, location, and criteria like job seniority, function and company size — which makes it the most useful ad library for B2B competitive research.

Which MCP clients does it work with? Both the hosted and self-hosted versions work with ChatGPT, Claude (Desktop and web), Cursor, Manus, and any other client that supports the Model Context Protocol.

Is there a free version? Yes — the hosted version from Proxy offers a free tier so you can start analyzing ads without any setup.

Should I self-host or use the hosted version? Use the hosted version if you just want fast, reliable access to LinkedIn Ad Library data with zero maintenance — this fits most users. Self-host only if you want to modify or extend the server code yourself.
