How is this different from a standard character splitter?

Standard splitters cut text at fixed intervals, often breaking sentences or separating headers from their content. This MCP uses Markdown headers and paragraph breaks to keep related information together.

What happens if a section is longer than my token limit?

The engine will look for the nearest paragraph boundary (double newlines) to split the text, ensuring you don't cut a thought in half.

Can I use this with Claude or Cursor?

Yes, you can use this with any MCP-compatible client like Claude, Cursor, or Windsurf once you connect it through Vinkius.

Does this MCP require me to host anything?

No, Vinkius hosts and manages the MCP for you. You just connect your client and it works.

How does it handle nested headers?

It recognizes all header levels from # through ###### and uses them to build a hierarchical path for every chunk created.

How does the chunking process maintain context?

The capability assigns a hierarchical path to every chunk, representing its position in the document tree (e.g., Parent > Child). This ensures that even when text is split, the structural lineage remains attached to the content.

What happens if a section is too large for the token limit?

If a header group exceeds the maxChunkSizeTokens, the engine identifies paragraph boundaries marked by double newlines and splits the content at these points to create smaller, valid chunks.

Can I preview the document structure before chunking?

Yes, you can use the get_header_structure capability to extract and view the identified heading hierarchy without performing the full chunking operation.

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 Markdown Semantic Chunker.

01
Generate semantic chunks
This capability creates logically grouped text segments from your Markdown files. It uses the document's header hierarchy to ensure chunks remain meaningful.
02
Get header structure
This capability pulls the full hierarchy of headers from a Markdown document. It's useful for previewing how the content is organized before you process it.
03
Calculate markdown token density
This capability measures the token density of your Markdown content. Use it to gauge how much information is packed into your text blocks.

Real work

What teams actually run

Technical Documentation RAG

Convert massive API docs into searchable chunks that keep instructions tied to their specific headings.

Automated Knowledge Base Indexing

Prepare company wikis for an AI agent by preserving the logical flow of the original documents.

Context Window Management

Use token density calculations to ensure your document chunks fit within your AI client's limits.

Document Outlining

Quickly extract the structural map of a complex Markdown file to understand its organization.

One connector, every AI

Markdown Semantic Chunker 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 Markdown Semantic Chunker 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.

Preview access · not provider authentication

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

It does not authenticate your account with Markdown Semantic Chunker. 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 Markdown Semantic Chunker owners hand off.

This MCP is built for engineers and data scientists building RAG-based applications who need high-fidelity document parsing.

01
AI Engineers
They hand off raw Markdown documentation to the MCP to prepare clean data for vector databases.
02
Data Scientists
They use the token density and structure capabilities to optimize how text is ingested into LLM workflows.
03
Knowledge Engineers
They use the header extraction to organize large technical manuals for better searchability.
