Zhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.

LiveAuth MCP Server gives AI agents cryptographic proof-of-work + Lightning Network authentication. Agents solve a PoW challenge, get a signed JWT, and use it to call paid MCP tools. Each tool call is metered in sats and recorded as a signed revenue event with a verifiable receipt. Built on L402 (the Lightning-Native HTTP 402 protocol from Lightning Labs). Compatible with x402 (Cloudflare/Coinbase). Non-custodial — no KYC, no account, no email. Pay per call in sats over Lightning.

Describe a real-world problem in plain language and Matchbox finds products built to solve it - with reasoning, honest caveats, what each product won't cover, and a frank 'no strong match' when nothing fits.

Tools: find_products_for_problem, search_catalog, get_product. No auth required.
