Write Middleware with Cursor

The `parse_accept_language` tool reads the exact header strings your application expects to receive. You trigger Agent mode while writing your routing functions. The editor passes sample headers to the tool and gets real JSON arrays back. Writing fallback logic usually involves guessing how browsers format their preferences. This MCP Server feeds actual, sorted weights into your code context. Your agent drafts the exact switch statements needed to handle those specific locales.

Debug Routing Logic Inline

A user reports seeing the wrong language on your site. You paste their exact Accept-Language header into the editor chat. The parser breaks down the values instantly. Trying to spot the priority error visually is a waste of time. The AI client reads the strict ordered list returned by the tool. It points out exactly which line in your codebase misread the fallback chain.

Generate Tests from Real Headers

Building test suites for global traffic requires realistic inputs. You ask the editor to create unit tests using a variety of complex header strings via this MCP Server. The tool processes these strings to define the expected outputs. Hardcoding mock data often misses edge cases like missing quality scores or malformed regions. The agent uses the live parser to generate accurate assertions. You get a test file that reflects actual browser behavior.

Setup guide

Set up Accept Language Parser MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Accept Language Parser MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Accept Language Parser transactions." If the MCP tools are loaded correctly, Cursor will call the Accept Language Parser tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "accept-language-parser-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}

Common questions about Accept Language Parser MCP in Cursor

Create an mcp.json file in your project root folder. Add the Vinkius endpoint token under the mcpServers object and turn on Agent mode.

Yes. The editor uses the parsed arrays to understand exactly how browsers rank languages. It writes middleware that correctly maps those ranks to your supported locales.

Language models fail at float math and strict sorting. Using this MCP Server guarantees the quality weights resolve correctly. Your code gets built on deterministic logic, not guesses.

It handles any valid BCP 47 language tag. The parser separates the primary language from the regional subtag while preserving the exact quality score.

Vinkius processes your raw header strings in ephemeral, zero-trust sandboxes. The execution environment vanishes the moment the parsed array returns to your editor. No traffic logs survive the session.
