What is tokenization drift?

Tokenization drift happens when the way a model breaks down text differs from what you expect, leading to unpredictable behavior or different token counts.

Which tokenizer profiles are supported?

The MCP supports profiles such as cl100k_base and llama.

How do I use this with Claude?

You connect the MCP through the Vinkius platform, which hosts it for you, and then it becomes available in your Claude client.

Can I check which rules are applied to a profile?

Yes, you can use the get_tokenizer_capabilities capability to see the specific normalization rules available for any profile.

Does this MCP handle Unicode issues?

Yes, it includes rules for Unicode standardization to prevent encoding-related tokenization errors.

Which tokenizers are supported?

The server supports various profiles including cl100k_base, p50k_base, and llama. You can use get_tokenizer_capabilities to see the full list of supported rules for each.

How do I use this with Cursor or Claude Desktop?

Connect via Vinkius Edge using your personal Connection Token. Once connected, any MCP-compatible client like Cursor, VS Code, Claude Desktop, or Windsurf can use the capabilities.

Connect Tokenization Normalizer 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. Ensure your agent sees exactly what you intended.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

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.

Curated set · 3 capabilities

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Tokenization Normalizer.

01
Get tokenizer capabilities
This capability tells you which specific normalization rules are available for a chosen tokenizer profile.
02
Analyze tokenization drift
Use this to compare your original text against a target profile to see how much instability exists for that model.
03
Normalize text structure
This capability transforms your input string to match the structural requirements of a specific target tokenizer.

Real work

What teams actually run

Prompt Engineering Stability

Normalize prompts to ensure they behave the same way across different model versions.

Token Budget Management

Check how text transformations affect the final token count for a specific model.

Deterministic Workflows

Prepare inputs for automated agents that require strict adherence to formatting.

Unicode Cleanup

Fix text containing unusual characters that might cause a model to misinterpret data.

One connector, every AI

Tokenization Normalizer 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 Tokenization Normalizer 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. 3 capabilities arrive 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 Tokenization Normalizer, so you can see the experience inside your AI.

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