How to Set Up and Use Open WebUI Plugins
Open WebUI Plugins is a curated collection of community-built extensions that enhance the Open WebUI AI chat interface with additional tools, skills, filters, pipes, and actions. The collection includes plugins for inline data visualization, email composition, MCP App Bridge integration, and preservation of reasoning chain-of-thought across tool calls. Developers and power users of Open WebUI install these plugins to customize their AI chat experience with specialized capabilities beyond the default interface.
Prerequisites
- A running Open WebUI instance (self-hosted or cloud-deployed)
- Open WebUI administrator access for installing Functions (filters, pipes, actions)
- Open WebUI workspace access for installing Tools and Skills
- Python 3.10 or later on the Open WebUI server for plugin execution
Browse the plugins collection
Visit the repository to browse available plugins. Each plugin lives in its own folder with a dedicated README describing what it does and how to install it.
Install a Tool plugin
For tool-type plugins, navigate to Workspace > Tools in Open WebUI and paste the plugin Python code into the tool editor, then save.
Install a Filter, Pipe, or Action plugin
For filters, pipes, and actions, navigate to Admin Panel > Functions in Open WebUI. Click 'Add Function', paste the plugin code, and save.
Configure the MCP App Bridge plugin
The MCP App Bridge plugin connects Open WebUI to MCP servers and renders their UI responses inline in chat. Install it as a Tool and configure your MCP server connection endpoint.
# Example MCP App Bridge configuration in the plugin settings:
# MCP_SERVER_URL: http://localhost:3000
# Renders MCP Apps via ui:// resources as HTML embeds in chatEnable the Inline Visualizer plugin
Install the Inline Visualizer v2 as a Tool to enable rendering of Chart.js, D3, Vega-Lite, ECharts, and Plotly visualizations directly inside chat responses.

Example prompts to use with Open WebUI plugins once installed.
- "Create a bar chart showing monthly sales: Jan 120, Feb 145, Mar 98, Apr 167"
- "Draft a professional email to decline a meeting invitation politely"
- "Show me the reasoning steps you used to answer my last question"
- "Connect to the MCP server and list available tools"Troubleshooting Open WebUI Plugins
Plugin code fails to save with a syntax error in Open WebUI
Ensure you copied the complete plugin file without truncation. Open WebUI validates Python syntax on save. Check for missing closing brackets, unclosed strings, or incorrect indentation in the pasted code.
Tool is visible but returns no output when called
Check the Open WebUI server logs for Python exceptions from the tool execution. Many tools require additional configuration (API keys, server URLs) that must be set in the tool's Valves/settings section in the UI before first use.
MCP App Bridge plugin cannot connect to the MCP server
Verify the MCP server URL is reachable from the Open WebUI server's network, not just from your browser. If Open WebUI runs in Docker, use the host's internal IP or Docker network hostname instead of localhost.
