Turn Instacart into MCP tools

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

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

Record the Instacart 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 Instacart account.

1. 1
   Record a Instacart action once

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

Example tool schema

{
  "name": "instacart.get_price",
  "description": "Return price and stock for an item at a store.",
  "input_schema": {
    "type": "object",
    "properties": {
      "query": { "type": "string", "description": "What to look up on Instacart." }
    },
    "required": ["query"]
  }
}

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

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

      "url": "https://api.usewrit.app/mcp/your-workspace",
      "headers": { "Authorization": "Bearer csk_3a90...f4d" }
    }
  }
}

Writ signs into your own Instacart account through a Persona to read store catalogs and prices inside that authenticated session.

Use Writ on your own Instacart account, within Terms of Service. Authorized automation of your own ordering.
