Mcp

Overview

Mcp is a Model Context Protocol server that lets you build, run, inspect, and publish browser extensions directly from any MCP client. With 30 tools across 11 browsers, it brings extension development into your AI workflow, letting Claude, Cursor, and other assistants handle extension tasks on your behalf.

The server runs locally via the npm package @extension.dev/mcp, communicating over stdio with no authentication required. Version v10.9.0 is available under the Apache-2.0 license, with full source code at extensiondev/mcp on GitHub.

Mcp lives in the AI & Agents category and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to verify ownership and keep information up to date.
