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

Automated Documentation Ingestion

Feed a new documentation URL into a collection to immediately update your agent's knowledge.

02

Local Model Testing

Run specific prompts through local Ollama models to compare outputs with cloud models.

03

RAG Pipeline Management

Upload files and monitor their processing status to ensure your vector DB is ready for queries.

04

Unified Chat Interface

Use a single agent to manage chats across different backend providers like OpenAI or Anthropic.

Automate a task

Put Open WebUI to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Open WebUI 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 Open WebUI 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.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 12 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 Open WebUI, so you can see the experience inside your AI.

It does not authenticate your account with Open WebUI. 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 Open WebUI owners hand off.

This MCP is built for technical users who already run their own LLM infrastructure and want to use it within their development environments.

  • 01

    AI Engineers

    They automate model testing and RAG configuration without switching to a browser.

  • 02

    Knowledge Managers

    They ingest documentation and web data into collections via simple text commands.

  • 03

    DevOps Teams

    They monitor local Ollama instances and manage model availability across teams.

FAQ

Questions Open WebUI owners ask.

  • 01

    How do I connect my Open WebUI instance?

    You need to provide your Open WebUI Base URL and your API Key during the setup process on Vinkius.

  • 02

    Can I use local Ollama models?

    Yes, this MCP includes specific capabilities to interact with the Ollama API for generation, tagging, and embeddings.

  • 03

    Does this work with Claude or Cursor?

    Yes, once connected, you can use these capabilities from any MCP-compatible client including Claude, Cursor, and Windsurf.

  • 04

    How does the RAG functionality work?

    You can upload files or process web URLs, which the MCP then stores in your Open WebUI collections for retrieval.

  • 05

    Is my data hosted by Vinkius?

    Vinkius hosts the MCP and manages the connection, but the actual model execution and data storage happen on your Open WebUI instance.

  • 06

    How can I check if a model is available in my Open WebUI instance?

    You can use the list_models capability. It will return a complete list of all configured models, including those from Ollama, OpenAI, and internal Open WebUI functions.

  • 07

    Can I add a website to my RAG collection using just a URL?

    Yes! Use the process_web_url capability. Provide the URL and the target collection name, and the server will scrape and index the content for you.

  • 08

    How do I know when my uploaded file is ready for querying?

    After using upload_file, you can check the ingestion progress by calling get_file_status with the returned File ID. It will tell you if the status is 'completed' or 'pending'.
