Builtwith

Overview

Builtwith is a Model Context Protocol (MCP) server: Detect technologies and tech stacks used on any website. In practice that means any MCP-compatible AI assistant can call Builtwith's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the Python package mcparmory-builtwith (via uvx) speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v1.0.3, with source at mcparmory/registry on GitHub, where it has earned 30 stars.

Builtwith is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
