Connect Language Detector Engine to ChatGPT and Claude

Set it up once and it works in ChatGPT, Claude, Cursor, and any other client you love. It all runs safely in the background, so you can relax and focus on what really matters. Stop your AI from guessing languages incorrectly.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Capability set01 / 01

01

1 capability in this set.

Part of 1 available through franc.

  1. 01

    Detect language

    This capability performs N-gram analysis to identify the language of a provided text string. It returns the corresponding ISO 639-3 code for one of over 400 supported languages.

Real work

What teams actually run

01

Automated Ticket Routing

Route incoming support messages to the correct regional queue based on exact language detection.

02

Data Cleaning

Identify and flag incorrectly labeled text in large multilingual databases.

03

Content Moderation

Detect the language of user-generated content to apply the correct regional safety filters.

04

Input Validation

Verify that user input matches the expected language before processing it through a translation pipeline.

Automate a task

Put franc to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

franc works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put franc to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 1 capability arrives ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of franc, so you can see the experience inside your AI.

It does not authenticate your account with franc. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work franc owners hand off.

This MCP is built for teams managing high-volume, multilingual text data where routing accuracy is critical.

  • 01

    Customer Support Managers

    They use it to ensure tickets are routed to the correct language-speaking agents.

  • 02

    Data Engineers

    They use it to validate and categorize large datasets containing diverse languages.

  • 03

    Localization Specialists

    They use it to verify the source language of content before translation begins.

FAQ

Questions franc owners ask.

  • 01

    How is this different from asking an AI to detect language?

    Standard AI uses probability to guess, which often fails on short text. This MCP uses deterministic N-gram math to provide a more reliable result.

  • 02

    How many languages does it support?

    The engine supports over 400 different languages.

  • 03

    What happens if the text is too short to identify?

    Instead of hallucinating a guess, the MCP returns an undefined result.

  • 04

    Can I restrict the detection to specific languages?

    Yes, you can use a whitelist to force the engine to only look for specific ISO codes.

  • 05

    What format are the language codes in?

    The capability returns standard ISO 639-3 codes, such as 'eng' for English or 'spa' for Spanish.

  • 06

    Why is this better than asking Claude to detect the language?

    LLMs often hallucinate languages for short strings or names. They also struggle to provide standardized ISO codes reliably. This engine uses mathematical N-gram analysis (the same technique behind Google Search language detection) to deterministically map text to one of 400+ ISO 639-3 codes.

  • 07

    What does it mean if it returns 'und'?

    'und' stands for Undefined. It means the text is too short, mostly numbers, or too ambiguous to confidently map to a single language. This is a feature. it prevents your routing logic from making false assumptions.

  • 08

    Can I force it to choose between specific languages?

    Yes. Pass an array of ISO 639-3 codes to the 'only' parameter (e.g., ['eng', 'por', 'spa']). The engine will only calculate probabilities within that subset.
