Turn Facebook Marketplace into MCP tools

Give your AI agent Facebook Marketplace tools. Writ turns your Facebook Marketplace workflows into authenticated MCP tools your agent can call, taking real actions on your own account.

  "mcpServers": {
    "writ-facebook-marketplace": {
      "url": "https://api.usewrit.app/mcp/your-workspace",

    }
  }
}

Record the Facebook Marketplace task once, or describe it to an AI session, and Writ turns it into an MCP tool your agent can call, taking real actions on your own Facebook Marketplace account.

1. 1
   Record a Facebook Marketplace action once

   Open the recorder and search a query and area on Facebook Marketplace in a real browser. Writ captures the steps, login and 2FA included, into a workflow.

2. 2
   Publish it as an MCP tool

   One click exposes the workflow as an MCP tool with a typed input schema, alongside a REST endpoint. Your agent picks it by its description.

3. 3
   Call it from any MCP client

   Point Claude Desktop, Claude Code, Cursor, or any MCP client at your Writ server. The Facebook Marketplace tool acts on your own account and returns structured output.

Browse supported MCP clients, see what's possible on workflows, or search for another site. Free to start. See pricing.

Read-only website-to-MCP tools can summarize a Facebook Marketplace page, but they can't do anything on it. Writ turns the Facebook Marketplace workflows you build into MCP tools your agent calls to take real actions (search, extract, submit), authenticated, on your own Facebook Marketplace account.

Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.

Each tool is a real Facebook Marketplace workflow with a typed input schema and structured output. Your agent picks the right one by its description.

Example tool schema

{
  "name": "fb_marketplace.search",
  "description": "Search a query and area and return local listings with prices.",
  "input_schema": {
    "type": "object",
    "properties": {
      "query": { "type": "string", "description": "What to look up on Facebook Marketplace." }
    },
    "required": ["query"]
  }
}

Copy the config into your client and authenticate with a wt_ key. Tools appear automatically.

  "mcpServers": {
    "writ-facebook-marketplace": {
      "url": "https://api.usewrit.app/mcp/your-workspace",
      "headers": { "Authorization": "Bearer wt_8f2c...a91" }
    }
  }
}

      "headers": { "Authorization": "Bearer csk_3a90...f4d" }
    }
  }
}

Writ signs into your own Facebook account through a Persona with 2FA and reads Marketplace listings inside that session.

Use Writ on your own Facebook account and on content you are authorized to access. Respect its Terms of Service.
