MCP server for link building

LinkBuilder.com MCP Server: the guest post catalog inside Claude, ChatGPT and Cursor

What your assistant can do with LinkBuilder.com

The assistant works with your own account: the same catalog, filters and limits as in the app.

  • Search the catalog

    Sites by niche, country, language, DR, traffic, domain zone, marketplace and price, sorted the way you ask.

  • Compare marketplace prices

    The best and median guest post price for each site and the sellers that offer it.

  • Work with projects

    List and create projects, use your saved filters, add sites to the white list or mark them as used.

  • Know your limits

    Ask what your plan includes and how much of it is left this month.

How to connect LinkBuilder.com to your AI assistant

  1. Add the server

    In your assistant, add a custom connector or MCP server with the address https://api.linkbuilder.com/mcp.

  2. Sign in and allow access

    The assistant opens LinkBuilder.com: sign in to your account and allow the connection on the consent screen.

  3. Ask in plain words

    Ask for sites, prices or your projects. The assistant picks the right LinkBuilder.com tool by itself.

Open the setup guide

Your account stays in your hands

  • Sign-in with OAuth: the assistant never sees your password.
  • No orders and no payments: the assistant can read the catalog and edit your projects, lists and filters, nothing more.
  • Your plan’s limits apply exactly as in the app.
  • Disconnect any assistant at any time on the MCP page of your account.

MCP is included in Professional and higher plans

Higher plans give the assistant more: more rows per search, more filters and projects, bigger lists.
