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.

Real work

What teams actually run

01

Passing Credentials in URLs

Instead of sending sensitive data in a standard URL, you can encode it using Base64URL to make it safe for web links.

02

Debugging Network Payloads

When debugging a system, you can use this MCP to decode a Hexadecimal string found in a network packet to see the original text.

03

API Payload Validation

Before sending a large JSON payload, you can use the byte size calculation capability to ensure it won't exceed the API's data limit.

04

Data Storage Preparation

If a database field has a strict character limit, you can encode the data using Base64 and check the resulting byte size.

One connector, every AI

Base64 and Hex Encoder/Decoder 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 Base64 and Hex Encoder/Decoder 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. 7 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 Base64 and Hex Encoder/Decoder, so you can see the experience inside your AI.

It does not authenticate your account with Base64 and Hex Encoder/Decoder. 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 Base64 and Hex Encoder/Decoder owners hand off.

This MCP is built for developers, data engineers, and backend specialists. If your job involves moving data between systems or preparing payloads for APIs, this capability is essential. It handles the low-level data formatting so you don't have to write custom encoding logic.

  • 01

    Backend Developer

    Needs to encode payloads for secure transmission or debug data formats.

  • 02

    Data Engineer

    Uses it to calculate precise byte sizes and ensure data fits within database constraints.

  • 03

    DevOps Specialist

    Requires it for debugging network traffic and verifying data integrity in deployment pipelines.

FAQ

Questions Base64 and Hex Encoder/Decoder owners ask.

  • 01

    Does this server require an API key?

    No, this server performs all mathematical conversions locally. No external APIs or authentication keys are required to use the encoding capabilities.

  • 02

    How can I check the size of my encoded payload?

    You can use the get_byte_size capability to calculate exactly how many bytes a string occupies in UTF-8 encoding.

  • 03

    Is Base64URL different from standard Base64?

    Yes, Base64URL is a variant of Base64 that replaces characters like '+' and '/' with '-' and '_' to ensure the string is safe for use in URLs.

  • 04

    Is Base64URL different from standard Base64?

    Yes, Base64URL is a variant of Base64 that replaces characters like '+' and '/' with '-' and '_' to ensure the string is safe for use in URLs.
