Puppeteer MCP ServerMCP Server44/100
via “wait conditions and element polling”
Automate browser interactions and take screenshots via Puppeteer MCP.
Unique: Exposes Puppeteer's wait primitives (waitForSelector, waitForNavigation, waitForFunction) as MCP tools, enabling LLM clients to synchronize automation with page state changes. Provides semantic feedback about wait outcomes (success, timeout).
vs others: Cleaner than raw JavaScript polling for LLM clients; built-in timeout handling and error reporting reduce the need for defensive code.
