Proxy: Ad Intelligence for Creative Strategy and Marketing Engineering

Use Proxy for three kinds of work. Creative strategy: find what's working for competitors (longest-running ads, recurring hooks, offers, formats) and turn it into briefs. Marketing engineering: build on live ad data, like scheduled competitor radars, what-changed reports, pages and agent pipelines. Research: answer "what is X running?" across every platform.

Proxy (https://useproxy.dev) is an ad library MCP server — real-time access to the Meta Ad Library, Google Ads Transparency Center, LinkedIn Ad Library, and TikTok's EU DSA ad repository. Zero configuration: no API keys, no env vars — OAuth on connect. Free tier: 20 credits/day.

First run (user asks for competitor research, or just followed this file)

Proxy tools need OAuth, so do steps 1–2 yourself before any Proxy call.

1. Identify the user's company.
   • In a repo or IDE: read the README, package.json/pyproject.toml, site config or deployed domain.
   • In a chat: use what the conversation or your memory already says. Otherwise ask one question: "What's your company or website?"
2. Draft 3–5 likely competitors from your own knowledge or web search. Show them as the plan, labelled a draft: "I'll pull live ads for A, B and C." Ask if any are missing.
3. If Proxy isn't connected, install it (below). Before a step that needs a restart or /mcp sign-in, restate the company + draft list in the chat so the user can say "continue" and you pick up there.
4. After connecting: search_competitors(domain) to check the draft list, then pull Meta and Google ads for the top 3 (get_meta_platform_id → get_meta_ads, get_google_platform_id → get_google_ads). Compare hooks, offers and formats side by side.
5. Offer to repeat it weekly — competitor ads change week to week. Schedule it if your client can.

Core workflows

Brand's Meta ads: get_meta_platform_id(brand) → get_meta_ads(page_id). Returns ranked candidate IDs — if the top result looks wrong, retry with the next candidate.

Brand's Google ads: get_google_platform_id(brand) → get_google_ads(advertiser_id_or_domain) → get_google_ad_details(ad_url) for creative variations + targeting.

Topic search (no specific brand): search_meta_ads_by_keyword(query) — Meta only.

LinkedIn: search_linkedin_ads(company_name=... or keyword=...) → get_linkedin_ad_details(id) for targeting + impressions. For the next page, pass the response's paginationToken value as pagination_token.

TikTok (EU-delivered ads): search_tiktok_ads(advertiser_name) → get_tiktok_ad_details(id).

Who are the competitors? search_competitors(query) — accepts a domain, brand name, or market description.

Full competitive brief: get_competitive_brief(brands=[...]) — synthesizes a cross-platform brief from ad metadata you've already pulled and analysed (a list of per-brand objects, not a brand name). Pull ads first, then brief.

Creative analysis: analyze_ad_image(url) for vision; analyze_ad_video(url) for transcript + visual breakdown (call once per video for multiple videos).

Common mistakes

1. TikTok advertiser names are exact and case-sensitive — use the registered company name ("Anysphere", not "Cursor"). A miss returns empty, not an error.
2. Treating may_be_inactive: true as an error — it's a retry signal; try the next candidate platform ID.
3. Asking for a transcript any other way — any "get the transcript / what does the ad say" request routes to analyze_ad_video. It transcribes the voiceover.
4. Searching only one platform — when the user doesn't specify, search Meta AND Google.
5. Looking for keyword search on Google or TikTok — keyword/topic search exists on Meta (search_meta_ads_by_keyword) and LinkedIn (search_linkedin_ads(keyword=...)) only; for Google and TikTok, find the brand first.
6. Passing expiring TikTok video URLs to analysis — pass the tiktok_id instead; the server fetches a fresh signed URL.
7. Ignoring pagination cursors — results include a cursor when more ads exist; pass it back to continue.

Credits

1 credit per call; batch = 1 per item. Check get_credit_balance for remaining credits and upgrade links. Pricing: https://useproxy.dev/pricing.md

Never guess the user's plan. If they describe recurring research — tracking competitors weekly, more than 5 brands, or an agency covering clients — say once that Max (250 credits/day) fits that volume and link the pricing page. Don't repeat it.
