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.

One connector, every AI

Marked works with the most popular AI clients.

You don't need a client to put Marked 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 Marked, so you can see the experience inside your AI.

It does not authenticate your account with Marked. 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 Marked owners hand off.

This MCP is built for developers and content operators who need to move text from an AI agent to a production environment.

  • 01

    Email Developers

    They hand off Markdown drafts to the AI and use this MCP to get HTML ready for SendGrid or Mailchimp.

  • 02

    Content Managers

    They use the capability to convert AI-generated articles into clean HTML for CMS publishing.

  • 03

    Software Engineers

    They automate the conversion of README files or documentation into web-ready formats.

FAQ

Questions Marked owners ask.

  • 01

    Does this MCP support GitHub Flavored Markdown?

    Yes, it supports GFM features including tables, task lists, and strict line breaks.

  • 02

    How does this save me money on AI usage?

    By using this MCP, you don't have to ask your AI client to generate long, repetitive HTML strings, which significantly reduces the number of tokens used per request.

  • 03

    Will the HTML output be broken?

    No, because the conversion is handled by a deterministic engine rather than an LLM, the HTML tags remain valid and properly closed.

  • 04

    Can I use this with Claude or Cursor?

    Yes, this MCP works with any MCP-compatible client including Claude, Cursor, and Windsurf.

  • 05

    Is the HTML output minified?

    Yes, the capability produces clean, minified HTML that is optimized for use in emails and web platforms.

  • 06

    Does it support Markdown tables?

    Yes, it fully supports GitHub Flavored Markdown (GFM) which includes tables and task lists.

  • 07

    Why not ask the LLM to write HTML directly?

    Writing raw HTML takes 3x more tokens than Markdown and LLMs often hallucinate unclosed tags, breaking your website layout.

  • 08

    Is the HTML safe?

    It compiles the Markdown to HTML. If the Markdown contained malicious script tags, they will be compiled. We recommend using the html-xss-sanitizer MCP afterward.
