Agent402 MCP Server

Tool selection in Agent402 starts with catalog.search for comparing candidates or catalog.find for matching a task to a suggested tool. The latter supplies a slug, price, input schema and example; catalog.call accepts the chosen slug and parameters. Research tools cover web and news searches, cited answers and Chromium rendering for JavaScript-heavy pages. Other listed tools retrieve market quotes, transcribe audio and maintain persistent memory tied to a paying wallet. The broader catalog includes PDF processing, image operations, OCR and data-format utilities.

Access differs between the hosted connector and a self-hosted instance. The connector can run free CPU utilities using proof-of-work, but it holds no wallet, so wallet-required calls return payment setup guidance instead of executing. payment.info explains funding, spending limits and wallet activity checks. Self-hosting supports a free mode, with optional per-call USDC payments on Base through x402. For ecosystem discovery, sellers.list exposes on-chain rankings for x402 and MPP sellers. When catalog discovery finds no suitable tool, demand.request records the missing capability without executing work.
