Needs a BrowserStack account and plan; open-source projects can get a free plan. The local server needs Node 20.9+ and can test localhost and staging. A hosted remote server at https://mcp.browserstack.com/mcp signs in with OAuth but cannot reach localhost. Five core tools search a catalog and run the capability you need; changes to data need your approval. File and app uploads need MCP_UPLOAD_BASE_DIR.
