KatanA Markdown Linter is a Model Context Protocol (MCP) server: Markdown linter, workspace-scoped stdio MCP server, and self-hosted text-only remote MCP server. Because it speaks the Model Context Protocol, AI assistants can use KatanA Markdown Linter as a set of callable tools instead of you copy-pasting between apps.
No credentials are required — it works out of the box. The current release is v0.19.4, published under the MIT license, with source at HiroyukiFuruno/katana-markdown-linter on GitHub.
