PostSnag connects to Claude through one link, so you can ask Claude about any profile, post, or group you've already captured without leaving the chat.

Before you start

  • PostSnag MCP is included with Pro and Lifetime. A Free account can add the connector, but every question comes back asking you to upgrade instead of an answer.

  • Your connector link, ready to copy:

    https://api.postsnag.com/mcp

  • Sign in to app.postsnag.com in the same browser first. Claude sends you to a PostSnag sign-in screen partway through, and being signed in already makes that step instant.

  • You've captured at least one profile, post, or group. The connector reads your PostSnag library; with nothing captured yet, there's nothing for it to answer from.

Connecting PostSnag MCP to Claude

  1. Open Connectors in Claude: go to Settings, then Connectors. Or open this link: https://claude.ai/customize/connectors?modal=add-custom-connector

  2. Add a custom connector: choose "Add custom connector," then paste in your PostSnag link.

    https://api.postsnag.com/mcp

  3. Sign in and you're connected: Claude opens a PostSnag sign-in screen. Sign in to PostSnag if it asks, and Claude has your library from that point on.

Important Note: PostSnag MCP also works in Claude Code and Claude Cowork, using this same link. Add it once and it connects the same way in either place.

Signing in to PostSnag

If you're already signed in to app.postsnag.com in that browser, Claude sends you straight back with nothing to click. If you're not signed in, PostSnag's own sign-in screen opens first: sign in with your email and password or Google, and you land back in Claude, connected. There's no key to create or paste anywhere in this flow, and PostSnag never touches your Facebook login.

Your first questions

Once it's connected, type a plain question straight into Claude. A few to try first:

  • "Which of my captured posts got the most shares last month?"

  • "Summarize everything I've captured from the profile I check most often."

  • "What's in my competitor folder, and which post did best?"

  • "How much of my scan quota do I have left this week?"

  • "Rank my best-performing posts by comments."

Checking it worked

Ask Claude: "How many posts have I captured?"

On Pro or Lifetime, you get a real number back, pulled straight from your own library. That count matches what you'd see on Posts inside your dashboard, since the connector reads the same library. On the Free plan, Claude relays this message instead:

"The PostSnag MCP connector is available to Pro and Lifetime members only. Please upgrade your account at https://postsnag.com to connect Claude, ChatGPT, or Perplexity."

Disconnecting

Remove PostSnag inside Claude's own Connectors settings, and the connection stops right away. Nothing changes inside PostSnag: your library, your scans, and your account stay exactly as they were. You won't lose anything you've already asked about; disconnecting just stops Claude from answering new questions until you reconnect. Reconnect any time with the same link:

https://api.postsnag.com/mcp

Common questions

Where do I find connectors in Claude?

Settings, then Connectors. Choose "Add custom connector" and paste the PostSnag link. Claude takes the link directly, with no developer mode to turn on first, which makes it the quickest of the four platforms to set up.

Does this work in the Claude desktop app, or just the browser?

Both. The connector is tied to your Claude account rather than to one app, so it works at claude.ai and in the Claude desktop app, with nothing extra to set up on the second one.

Does connecting this give Claude my Facebook login?

No. PostSnag never holds your Facebook password, and the connector only exposes what you've already captured to your PostSnag library. Your Facebook session stays in your own browser, where the extension uses it.

Can Claude go capture something new for me?

No. The connector reads your captured library; it has no Facebook access of its own. Asking Claude to go snag a new profile won't work. Capturing still happens in the Chrome extension while you scroll.

Do I need to reconnect after upgrading from Free to Pro?

No. The connector doesn't check your plan when you add it, only when you ask a question. Upgrade your PostSnag plan and your next question in Claude works, with nothing to reconnect.
