MCP-B/WebMCP
Built at OpenAI GPT-5 Startup Hackathon · Aug 9, 2025
A feature which let's an AI develop and inject MCP servers into webpages as userscripts. This MCP server can then be used by GPT-5 via the mcp-b chrome extension. I built the userscript repo which the cursor gpt-5 agent can use to test it's userscript script webmcp server. Then i built out the bridge to let the agent upload the script to the extension so the extension agent can use the tools for that website
