4.52.2 - MCP Server Support

MCP Server Support

If you love AI tools, this is one of the biggest releases this year for SeleniumBase!
The new seleniumbase-mcp command starts the "Pure CDP Mode" MCP Server.
(Be sure to install seleniumbase[mcp] to get mcp>=2.0.0!)
(To debug the MCP server from a git clone of SeleniumBase, get uv as well before calling mcp dev server.py from the SeleniumBase/mcp_servers/ folder.)

• Add a SeleniumBase MCP server
• Add .mcp.json to the root folder
• Update setup.cfg files
• Update .gitignore
• Update .dockerignore
• Add configuration for using the new MCP server
• Refresh Python dependencies
• Update ReadMe files

Note that you will need mcp>=2.0.0 for the MCP Server to work!

⚠️ Note: Due to a typing bug, (#4471), the MCP Server in this release only worked on Python 3.14+.
Upgrade to https://github.com/seleniumbase/SeleniumBase/releases/tag/v4.52.3 for the fix.
