Decode Headers in Claude Desktop

The `parse_accept_language` tool breaks down raw HTTP Accept-Language strings into a clean, ordered list. You paste the header from your server logs directly into the chat interface. Your agent reads the quality weights and sorts the locales by user preference. Manual parsing leads to subtle bugs when dealing with float values. This MCP Server handles the math for you. You get a strict priority array back, letting you figure out exactly why a French user saw the Spanish fallback page.

Test i18n Logic Instantly

Routing logic breaks when browsers send weird regional dialects mixed with broad language codes. You feed those edge-case strings to the parser. The tool evaluates the exact weight of each locale. Building middleware requires knowing exactly how these arrays resolve. You ask your AI client to simulate requests from different global regions. The output shows you the precise fallback chain your application will follow.

Fix Production Locale Bugs

Support tickets often include raw request headers that look like garbage text. You drop that text into the prompt for this MCP Server. The parser separates the primary language from the secondary options. Figuring out why a specific user got the wrong translation takes seconds instead of hours. The agent maps the parsed weights against your supported languages. You find the gap in your coverage immediately.

Common questions about Accept Language Parser MCP in Claude Desktop

You have two paths. Add the Vinkius endpoint URL to your claude_desktop_config.json under the mcpServers key and restart the app. If you use the web version, paste the HTTPS URL into Settings, then Integrations.

Yes. The parser assigns a default weight of 1.0 to any language code missing an explicit parameter. It sorts those to the top of the list automatically.

Large language models hallucinate math and sorting logic. The tool uses deterministic code to evaluate quality weights. You get guaranteed accuracy for your routing logic.

You get a structured JSON array back. Each object contains the language code, the region if specified, and the exact float value of its quality weight.

Vinkius runs this tool inside a V8 Isolate Sandbox that destroys itself after execution. The server processes your raw header strings in memory and returns the parsed array. Nothing gets logged or saved to disk.
