I open-sourced a linter for MCP tool descriptions
A developer published an open-source linter for MCP tool descriptions on DEV Community, announced in a post dated October 8, 2026. The article page carries the site's "418 Challenge" retro theme styling, which restyles cards, headers, tags, and links with Windows 95 and 1999 hacker aesthetics. Beyond the title and the styling markup, the provided source text contains no details about the linter's rules, supported formats, or installation.
Developers working with MCP tool descriptions now have an open-source linter option, though the source text provides no details on its rules or usage.
