BuiltWith API as an MCP server for Claude Desktop, Cursor, and other AI clients
BuiltWith API as an MCP server for Claude Desktop, Cursor, and other AI clients. That is what the builtwith mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
Query the BuiltWith API from your app, terminal, or AI agent.
Installation goes through your MCP client rather than a global install: point it at @modelcontextprotocol/inspector on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
The server publishes 14 tools. What each one is for:
Method — Descriptionfree — Free technology summarydomain — Full domain technology lookuplists — Sites using a technologyrelationships — Related domainskeywords — Domain keyword extractiontrends — Technology adoption trendscompanyToUrl — Company name to domainsdomainLive — Live domain detectiontrust — Trust & fraud signalstags — IP & attribute lookupsrecommendations — Technology suggestionsConfiguration is passed through the environment: BUILTWITH_API_KEY, YOUR_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of payments and commerce servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Builtwith's toolset — Method, free, domain and 11 more — is a fair guide to whether it matches your workflow. It is maintained by zachcaceres; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
