Bots are automated or semi-automated processes that edit pages with reduced or no direct human supervision. Because bots may potentially strain server resources or accidentally disrupt the project, bots must follow special policies and guidelines. Additionally, as bots can be used to intentionally create vast amounts of damage very quickly, bots editing very quickly without permission (a bot "flag") or in a questionable manner, will be immediately blocked. Running a bot on a normal (human) account is not allowed, a bot must have its own account, generally including the word "bot" in the name and preferably some way to connect it to the operator (e.g. User:RobBot operated by User:Robchurch). Mediawiki.org generally follows the policy stated at meta:Bot policy; however, as a development project, user trustworthiness and experience are of greatest importance and little to no discussion may take place before granting, or denying, a bot flag. Inactive bots may have their flags summarily removed for security purposes, the bot flag is merely intended to indicate that the bot is allowed to make relatively high speed direct edits for the purposes for which it was approved. Because this is a development project, the normal rules for bots on other WMF projects may not apply here, especially to developers.
There is some use for bots on mediawiki.org, but it is not the same as on community content based WMF projects, such as Wikipedia. Please post a request at Project:Requests if you plan to run a bot on MediaWiki.org. You may also speak to a bureaucrat directly via talk page or IRC, though request from new, inexperienced, or unknown users will generally be denied.
