Turn Costco into MCP tools

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

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

Record the Costco 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 Costco account.

1. 1
   Record a Costco action once

   Open the recorder and search a keyword on Costco 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 Costco 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 Costco page, but they can't do anything on it. Writ turns the Costco workflows you build into MCP tools your agent calls to take real actions (search, extract, submit), authenticated, on your own Costco 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 Costco workflow with a typed input schema and structured output. Your agent picks the right one by its description.

Example tool schema

{
  "name": "costco.get_price",
  "description": "Return member price and stock for a product URL.",
  "input_schema": {
    "type": "object",
    "properties": {
      "query": { "type": "string", "description": "What to look up on Costco." }
    },
    "required": ["query"]
  }
}

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

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

    }
  }

    }
  }
}

Writ signs into your own Costco membership through a Persona to read member pricing and availability inside that session.

Use Writ on your own Costco membership for actions you are entitled to take. Respect its Terms and purchase limits.
