Overview

Ketch provides a unified interface for AI agents and developers to perform web operations. It features concurrent batch scraping, multi-engine federated search using Reciprocal Rank Fusion, code grepping, documentation retrieval, and breadth-first web crawling. It operates statelessly with local TTL caching and offers both a CLI and an MCP server integration.

Capabilities

▸Web search across multiple backends with federated RRF fusion
▸Concurrent URL scraping with smart input detection and automatic JS-shell rendering
▸Source code search across platforms like GitHub and Sourcegraph
▸Documentation search and resolution
▸BFS and sitemap web crawling with depth limits and background processing
▸Model Context Protocol (MCP) server support over stdio

Best for

AI agents executing real-time web searches and context scraping during reasoning loops., Developers searching for code snippets across open-source repositories via the command line., Gathering and converting live web pages or sitemaps into clean Markdown for documentation or RAG pipelines.

Security considerations

The MCP server and CLI execute arbitrary URL fetching and crawling without built-in output filtering or private IP blocking. Running the server grants the connected agent the network posture of the host machine.
