Linkedin Campaign Manager MCP Server

LinkedIn Campaign Manager MCP

MCP server for the LinkedIn Marketing API — query campaigns, performance, and Lead Gen Forms from Claude in plain English.

19 read-only tools covering ad accounts, campaigns, creatives, performance analytics, demographics, video analytics, budget pacing, period comparisons, conversions, Lead Gen Forms, audiences, and targeting facets. Built for B2B paid social teams running Sponsored Content, Lead Gen Forms, and account-based campaigns on LinkedIn.

Why this exists

The LinkedIn Marketing API is notoriously painful to work with: monthly Rosetta versioning, undocumented field mappings, Rest.li-style nested query params for analytics, and 60-day access tokens that silently expire. This server handles all of that under the hood so you can ask questions in plain English instead of hand-writing dateRange=(start:(year:...)).

No other open-source MCP server for LinkedIn Ads ships this depth. Most stop at "list campaigns." This one includes demographics, video completion funnel, budget pacing, period comparisons, and Lead Gen Form responses with PII so you can reconcile leads against Marketo or Salesforce.

Example prompts

Once installed, ask Claude things like:

• "What's our LinkedIn Ads spend trend the last 28 days, broken down by campaign group?"
• "Compare CPL on the competitor-conquest campaigns this month vs. last — which creatives moved the number?"
• "Pull demographics for our top-spending campaign — what seniority and industry are converting?"
• "Which Lead Gen Forms had the highest submit rate last month, and what did each cost per lead?"
• "Show the video completion funnel for our awareness campaign — where are people dropping off?"
• "Are any campaigns at risk of overspending? Show budget pacing across all active ones."
• "Pull yesterday's Lead Gen Form responses so I can spot-check them against Marketo."

Tools

Setup

1. Install

npm install -g linkedin-campaign-manager-mcp

Or clone + build locally:

git clone https://github.com/ZLeventer/linkedin-campaign-manager-mcp
cd linkedin-campaign-manager-mcp
npm install
npm run build

2. Create a LinkedIn Developer App

The Marketing API is gated. You need a LinkedIn Developer App with specific product approvals:

1. Go to developer.linkedin.com → Create App (associate with your company page).
2. Products tab — request access to:
   • Marketing Developer Platform (covers r_ads, r_ads_reporting)
   • Lead Gen Forms or Community Management API (covers r_ads_leadgen_automation)
3. LinkedIn reviews app access manually — typically 2–6 weeks.
4. Auth tab → Authorized Redirect URLs — add: http://127.0.0.1:53123 (change 53123 if you set a different LINKEDIN_OAUTH_PORT).
5. Copy Client ID and Client Secret from the Auth tab.

Without product approval every API call returns 403. The server compiles and starts cleanly — the 403 is an app-level permission issue, not a code issue.

3. Configure environment

cp .env.example .env
# edit .env with your LINKEDIN_CLIENT_ID, LINKEDIN_CLIENT_SECRET,
# LINKEDIN_DEFAULT_AD_ACCOUNT (numeric ID from Campaign Manager URL)

4. Authorize (one-time OAuth flow)

npm run auth

This opens a local HTTP server on port 53123 (or LINKEDIN_OAUTH_PORT), prints an auth URL to your terminal, and waits for the OAuth callback. After you approve in the browser, it exchanges the code for an access token + 365-day refresh token and saves them to token.json (mode 0600).

You only need to re-run npm run auth if the refresh token expires (after 365 days).

5. Wire into Claude Code (or any MCP client)

Add to ~/.claude.json under mcpServers:

{
  "mcpServers": {
    "linkedin": {
      "command": "linkedin-campaign-manager-mcp",
      "env": {
        "LINKEDIN_CLIENT_ID": "your_client_id",
        "LINKEDIN_CLIENT_SECRET": "your_client_secret",
        "LINKEDIN_TOKEN_PATH": "/absolute/path/to/token.json",
        "LINKEDIN_DEFAULT_AD_ACCOUNT": "123456789",
        "LINKEDIN_API_VERSION": "202504"
      }
    }
  }
}

Or if running from source:

{
  "mcpServers": {
    "linkedin": {
      "command": "node",
      "args": ["/path/to/linkedin-campaign-manager-mcp/dist/index.js"],
      "env": {
        "LINKEDIN_CLIENT_ID": "...",
        "LINKEDIN_CLIENT_SECRET": "...",
        "LINKEDIN_TOKEN_PATH": "/path/to/token.json",
        "LINKEDIN_DEFAULT_AD_ACCOUNT": "123456789"
      }
    }
  }
}

Restart Claude Code. The 19 tools appear under the linkedin server.

Environment variables

---

URN handling

LinkedIn resources are identified by URNs: urn:li:sponsoredAccount:123, urn:li:sponsoredCampaign:456, etc.

All tool inputs accept either the bare numeric ID or the full URN — the client wraps bare IDs automatically. Numeric IDs appear in Campaign Manager URLs (/accounts/<id>/, /campaigns/<id>/).

---

Date inputs

All date parameters accept:

Default range: 28daysAgo → yesterday.

LinkedIn-specific gotchas

API version churn

LinkedIn Rosetta uses monthly versions (202504 = April 2025). Versions deprecate ~12 months after release — you'll get 410 Gone errors when that happens. Bump LINKEDIN_API_VERSION quarterly. See the versioning docs.

Analytics query shape

/adAnalytics uses Rest.li-style nested params, not plain ISO strings:

dateRange=(start:(year:2024,month:10,day:1),end:(year:2024,month:10,day:31))
campaigns=List(urn:li:sponsoredCampaign:123,urn:li:sponsoredCampaign:456)

This is handled internally by dateRangeParam() and liGetRaw(). If you extend the server, route analytics calls through liGetRaw() with a manually-built URL — do not use liGet() for analytics endpoints as URLSearchParams will mangle the nested parens.

Analytics data lag

LinkedIn analytics typically lag 2–6 hours for most metrics, and up to 24 hours for conversion data. Yesterday's numbers are usually complete; today's are partial.

60-day access tokens, 365-day refresh tokens

Access tokens expire in 60 days; refresh tokens in 365 days. The client auto-refreshes the access token on every request when needed. If the refresh token expires, run npm run auth again.

Lead Gen response PII

li_get_leadgen_responses returns actual lead PII — name, email, company, job title. Treat output as sensitive: do not write to shared logs, unencrypted storage, or public channels. LinkedIn's data-use policy requires deleting lead responses within 90 days of receipt unless the lead is actively consented. This tool is intended for authorized CRM reconciliation (Marketo/SFDC).

Rate limits

LinkedIn does not publish hard rate-limit numbers. In practice, expect throttling around 100 analytics calls/minute per app. No retry-on-429 is built in — if you hit limits, reduce call frequency or cache results client-side.

When NOT to use this server

• Creating or editing campaigns, budgets, or creatives — read-only by design. Campaign creation has too many failure modes to automate safely; use the Campaign Manager UI.
• Real-time impression data — use the LinkedIn Insight Tag + GA4 for near-realtime.
• Audience size estimation for arbitrary targeting criteria — use the Campaign Manager audience builder UI for ad-hoc sizing. li_get_audience_insights only returns sizes of saved/uploaded segments.
