## Questions

### Is there an official Open WebUI MCP server?

Popular self-hosted AI interface whose MCP coverage is community led. mcpheaven lists Open WebUI so agents can find it by task and reach it through one MCP endpoint.

### What can an AI agent do with Open WebUI?

Manage models, knowledge bases, conversations, and users. Agents find it by describing the task, for example with the search_capabilities tool.

### How do I connect Open WebUI to Claude, Codex or Cursor?

Add mcpheaven once as an MCP server (https://mcpheaven.com/mcp) with an API key, then ask your agent for the task. It calls get_capability with the slug "open-webui" for details.

### Is the Open WebUI integration available?

The Open WebUI integration is planned. Agents can already discover it through mcpheaven's search, and it will become callable once the integration ships.
