Give Claude Desktop real web actions on any site

Give Claude Desktop real web actions on any site (login, forms, multi-step tasks) over MCP.

{
  "mcpServers": {
    "writ": {
      "url": "https://api.usewrit.app/mcp",
      "headers": { "Authorization": "Bearer wt_your_api_key" }
    }
  }
}

Claude Desktop speaks MCP natively. Point it at your Writ server and every workflow you publish becomes a tool Claude can call: authenticated, on your own accounts, on sites that have no API of their own.

1. 1

   Claude reads each tool's description and input schema, so it picks the right Writ workflow for the task on its own.

2. 2

   Tools run the real browser flow (login, TOTP and mailbox-OTP 2FA, dynamic pages) and hand structured JSON back to the chat.

Each tool is a published browser workflow - it acts on the live site, then returns structured output.

Paste the server block, authenticate with a scoped wt_ key, and your published workflows appear as tools.

{
  "mcpServers": {
    "writ": {
      "url": "https://api.usewrit.app/mcp",
      "headers": { "Authorization": "Bearer wt_your_api_key" }
    }
  }
}

1. 1
   Step 1

   Open Claude Desktop → Settings → Developer → Edit Config.

2. 2
   Step 2

   Add the "writ" server block to mcpServers with your wt_ API key.

3. 3
   Step 3

   Restart Claude Desktop; your Writ workflows appear as tools.

The sites worth automating are usually the hard ones. Claude Desktop gets tools that handle them.

Because every tool runs the real browser flow, Claude Desktop can complete tasks a read-only MCP server never could: sign in, pass two-factor, navigate pages that render with JavaScript, and submit. It runs on your own accounts and credentials, on sites you are authorized to use.

All three produce the same callable workflow - which becomes a tool the moment you publish it.
