Sets up a proxied Jupyter UI Tools MCP server that allows conflict resolution with an enterprise MCP config for Claude Code.

The current MCP setup implements the jupyter UI tools MCP server as an in-process MCP server which gets passed to the claude-agent-sdk and then passed to the Claude Code CLI as it's own MCP config with --mcp-config. This will conflict with an enterprise MCP config (managed-mcp.json) file, causing an error to be thrown by the Claude Code CLI and then the Claude Mode sidebar to fail.

This proxied jupyter UI tools MCP server is a mimic of the current in process server, except it runs in the same jupyterlab server through a proxy URL. This allows developers to modify their enterprise MCP config to add a section for this proxied MCP server so that it will work in the same way as the in-process MCP server

A toggle is provided which allows developers to choose whether they want the proxied MCP jupyter UI tools server, or the original in-process one. The default is the original in-process jupyter UI tools server. Using the proxied MCP server requires the enterprise MCP config to also register this server.
