Preview access · not provider authentication

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

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

FAQ

Questions Node Buffer owners ask.

  • 01

    Does it support URL-safe Base64?

    Yes, just pass base64url as the format argument. It removes + and / characters.

  • 02

    Is this needed if my LLM can write code?

    Yes, because the LLM is running in a sandbox without a Node.js runtime. This MCP gives the LLM direct access to Buffer execution.

  • 03

    What happens if I try to decode an invalid Base64 string?

    The V8 engine will safely catch the error and return a formatted error message without crashing your agent.
