Facebook Marketplace API for AI agents: listings, Pages, posts and ads

    Let Claude, ChatGPT, Cursor or Codex read public Facebook data: Marketplace listings by keyword and place, Pages and their posts, comments, public groups and events, and ads from the Meta Ad Library. It comes from third-party data providers and the Ad Library, so you don't sign in to Facebook or manage API keys. Your agent pays per call.

    78 tools and 5 skills that use them. Pay per use from one balance, no API keys.

    How to choose the best Facebook data tool or MCP for you

    Search first, then look up

    Search Marketplace or public posts to see what's there, then look up single listings or posts only for the ones you need.

    Location

    Marketplace search works near a place. A location lookup turns a city name into the coordinates some Marketplace tools ask for.

    One advertiser or a whole market

    To study a competitor, list the ads one Page runs. To see a market, search the Ad Library by keyword. EU reach and political ad spend have their own tools.

    Public data only

    The tools cover public Pages, posts, public groups, events, Marketplace listings and the Ad Library. Private groups and profiles aren't included.

    Why use Agensi instead of separate Facebook data MCPs?

    Building this yourself means a separate scraper or data API for each part of Facebook, each with its own key and code to maintain. With Agensi your agent reads Marketplace listings, Pages, posts, groups, events and the Meta Ad Library through one connection and pays per call from one balance. Your Facebook account is never connected. Your agent runs a tool from your balance and tells you what it found and what it cost. Failed uses are free.

    When another way is the better choice. If you manage your own Pages, ads or product catalog, use Meta's own tools with your business account: they show your own results and messages, which public data tools can't see. For heavy Ad Library research, Meta's own Ad Library API is the direct route.

    Set up in your AI agent

    Connect your AI agent to Agensi once, sign in and click Allow. After that it can use every tool: it runs one from your balance and tells you what it cost. No API keys or provider accounts.

    1. Open Settings, then Connectors, then Browse connectors and add Agensi (or Add custom connector and paste https://mcp.agensi.io/mcp/auth).
    2. Sign in to Agensi and click Allow. One agent per account: connecting a new one disconnects the old one.
    3. Ask for what you want, for example: "Find used road bikes for sale near Austin on Facebook Marketplace, read the five best matches and tell me what a fair price is." Top up from $5 if your balance is low; failed uses are free.

    Grok, VS Code, GitHub Copilot, Cline, Kiro and other agents with remote MCP and sign-in work too: see the setup guide.

    Combine Facebook data tools with skills

    Facebook data MCP: frequently asked questions

    No. Agensi isn't made by or affiliated with Meta. The tools return public Marketplace listings, Pages, posts and events from third-party data providers, and ads from the Meta Ad Library, through one Agensi connection. You don't need a Facebook developer app or an API key, and your Facebook account is never connected.

    Public data only: Marketplace listings and their details, Pages with their posts, photos, reels and events, comments and replies, posts in public groups, public events and ads from the Meta Ad Library. Tools that return a Page's email or phone number, and people search by name, are left off this page. Meta's terms and privacy law apply to how you use the data.

    Yes, by searching again. Each search returns the listings that are up at that moment, so ask your agent to run the same search later and compare with the results it saved, for example in a file in Claude Code. Each search is charged like any other call, and failed calls are free.

    Each tool shows its live price in the list on this page; most are charged per call. Your agent runs it from your balance and tells you what it cost. In Dashboard → Balance you can have it ask first, or only above an amount per use and per day. Failed uses are free.
