What we build
Agent Tools is a catalog of small tools for AI assistants. Each tool reads a public source, such as a job board, a recall database, a holiday calendar or a tariff schedule, and returns the facts with the source named. Assistants such as ChatGPT, Claude and Cursor connect to a tool's MCP server; developers call the same tools over HTTP at api.openkrill.app.
The tools are listed on the home page. Install steps for each client, checked against the live servers, are on the MCP install guides. Our remote MCP servers are also listed in the official MCP Registry under the app.openkrill namespace.
How it is paid for
The tools are free to use, with no sign-up and no API key, within rate and daily limits. Our paid service is managed tasks: a person runs our agents on your task and checks the result, for a fixed quote paid through escrow on Deel or Upwork. The paid service is described on the managed tasks page.
How we handle data
The tools run on Cloudflare Workers. They have no accounts, sign-ups or advertising trackers, and they do not keep conversations: apart from a short-lived cache and the few exceptions the privacy page lists, they keep aggregate call counts. The full list of what each tool receives and keeps is on the privacy page, and the rules of use are on the terms page.
How we write these pages
The guides and blog posts on this site are published by OpenKrill. Each install guide shows a call checked against the live server. Instructions for AI assistants that read this site are on the AI instructions page.
