Compatible with every major AI agent and IDE
What is the Open WebUI MCP Server?
Connect your Open WebUI instance to any AI agent and take full control of your local and cloud LLM orchestration through natural conversation.
What you can do
- Model Management — Use
list_modelsto fetch all available models including Ollama, OpenAI, and Open WebUI Functions. - RAG & Knowledge Base — Upload files with
upload_file, process web content viaprocess_web_url, and organize them into collections usingadd_file_to_collection. - Chat Orchestration — Create and manage backend-controlled chats with
create_new_chator use OpenAI/Anthropic compatible endpoints likechat_completionsandsend_message. - Native Ollama Support — Directly interact with the Ollama API using
ollama_generate,ollama_tags, andollama_embedfor local inference tasks. - File Processing — Monitor the status of your document ingestion with
get_file_statusto ensure your RAG context is ready.
How it works
- Subscribe to this server
- Enter your Open WebUI Base URL and API Key
- Start managing your LLM infrastructure from Claude, Cursor, or any MCP-compatible client
Who is this for?
- AI Engineers — automate the testing of different models and RAG configurations without leaving the terminal or IDE.
- Knowledge Managers — quickly ingest documentation and web URLs into Open WebUI collections via simple commands.
- DevOps Teams — monitor local Ollama instances and manage model availability across the organization.

Why Claude Code?
Claude Code registers Open WebUI as an MCP server in a single terminal command. Once connected, Claude Code discovers all 12 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where Open WebUI data drives decisions without human intervention.
- —
Single-command setup:
claude mcp addregisters the server instantly. no config files to edit or applications to restart - —
Terminal-native workflow means MCP tools integrate seamlessly into shell scripts, CI/CD pipelines, and automated DevOps tasks
- —
Claude Code runs headlessly, enabling unattended batch processing using Open WebUI tools in cron jobs or deployment scripts
- —
Built by the same team that created the MCP protocol, ensuring first-class compatibility and the fastest adoption of new protocol features

Why teams choose Vinkius for Open WebUI in Claude Code
The Open WebUI MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 12 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Claude Code only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
Open WebUI for Claude Code
Every tool call from Claude Code to the Open WebUI MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How can I check if a model is available in my Open WebUI instance?
You can use the list_models tool. It will return a complete list of all configured models, including those from Ollama, OpenAI, and internal Open WebUI functions.
Can I add a website to my RAG collection using just a URL?
Yes! Use the process_web_url tool. Provide the URL and the target collection name, and the server will scrape and index the content for you.
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'.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
