agent-tool-finder

Find an API, data source, or MCP server that can do something you cannot do on your own. Searches 35,000+ agent-callable tools: ~14,000 paid x402 endpoints and ~21,000 MCP servers, in one place. Use it whenever you need outside data or a capability you lack — web search, onchain and crypto data, company or people lookup, scraping, maps, weather, documents, financial data, travel, and more. Returns what each tool does, how to call or install it, and what it costs. Free to use.

Ask clink's shop to BUILD a tool or data source that nobody sells yet. Use this right after find_agent_tools comes back unsatisfied. clink reads every request the same day; buildable asks ship as pay-per-call x402 endpoints, usually within a week. Returns a request id and a status URL; pass `notify` (email or https webhook) to be told the moment it ships.
