What Open WebUI does with MCP
Open WebUI supports MCP starting with version 0.6.31. It connects to MCP servers using the Streamable HTTP transport, and users can call the tools exposed by a connected server from Open WebUI. See the Open WebUI MCP documentation.
Connect the hosted KnowMan server
KnowMan provides a hosted Streamable HTTP MCP server at https://api.knowman.io/mcp. Sign in with OAuth and approve its consent request, or send an API key as Authorization: Bearer <key>. Both authentication methods are documented in the KnowMan MCP repository.
Add KnowMan in Open WebUI
In Open WebUI, an administrator adds MCP servers under Settings > Admin > Integrations. Set the type to MCP (Streamable HTTP), add https://api.knowman.io/mcp, and use OAuth or a bearer token as required by your authentication choice. See Open WebUI's MCP guide.
Search, ask, and read saved items
KnowMan MCP exposes six tools for searching, asking, reading, saving, listing recent items, and retrieving memories. The tools are kb_search, kb_ask, kb_get_item, kb_save, kb_recent, and kb_memories. See the KnowMan MCP repository.
Control access to the connection
Open WebUI administrators can scope an MCP server to selected users or groups with Access Control. This lets an admin add the server once and control who can use it. Open WebUI reserves MCP registration for administrators because servers can have powerful capabilities and access user data. See the Open WebUI MCP documentation.
Understand OAuth permissions
KnowMan's consent flow separates knowman.read for search, reading, and asking from knowman.write for saving links. Its access tokens last one hour and refresh automatically. See the KnowMan MCP repository.
Where KnowMan fits
KnowMan fits as the knowledge layer behind Open WebUI. It keeps saved articles and links available through tools for search, questions, content reading, saving, recent items, and memories. Learn more about MCP servers for personal knowledge bases and connecting AI to your notes.
