Agent Tools by OpenKrill provides free MCP servers and streamable HTTP data APIs for AI agents and developers. It exposes 40 tool servers with 140 callable tools covering job listings, app store reviews, X posts, CVE checks, SEO audits, recalls, transcripts, and other live public data. Tools connect via Model Context Protocol streamable HTTP to clients such as Claude, Claude Code, Cursor, ChatGPT, and n8n, or via REST JSON at api.openkrill.app. Usage is free within rate limits (60 calls/minute per network per tool server, 20 requests/minute and 200 tool calls/day per network on the shared API); an optional API key sent in the x-api-key header lifts the limits.
