How to connect Open WebUI to Anchor
Step-by-step setup for every MCP-compatible agent. One URL, OAuth sign-in, and you're done.
Open WebUI
An admin completes the one-time server setup, then each user enables Anchor per-chat.
Admin setup
- Go to Admin Panel → Settings → Integrations → Manage Tool Servers and click the + button.
- Fill in the Add Connection dialog:
- Type: MCP Streamable HTTP
- Name: Anchor
- URL:
- Auth: OAuth 2.1
- Click Register Client (top-right of the Auth row). Wait for the badge to flip from orange Not Registered to green Registered.
- Click Save.
Per-chat usage
- Start a New Chat.
- Click the wrench icon in the chat box (bottom-left of the message input).
- Toggle Anchor on under Available Tools.
- Pick a tool-capable model from the model dropdown (e.g.
anthropic/claude-sonnet-4-5). - Ask "List my Anchor orgs." The first time, a sign-in window opens — use your Anchor account to connect.
- Ask "What is Anchor, and what can I use it for?"
