katana-markdown-linter 0.19.3

Fast Markdown linter and formatter with localized CLI help and version aliases.

katana-markdown-linter Python wrapper

katana-markdown-linter is a thin Python launcher over GitHub Release binary archives. The package does not contain independent lint or MCP server logic. On first use, it downloads the matching kml, kml-mcp, or kml-mcp-remote binary archive, verifies the neighboring SHA-256 checksum, installs the binary into the wrapper cache, and delegates to that binary.

Install

pipx install katana-markdown-linter
kml --version

Use uvx for one-off runs:

uvx --from katana-markdown-linter==0.19.3 kml --version
uvx --from katana-markdown-linter==0.19.3 kml check README.md

Basic Usage

# Run linting
kml check README.md

# Show help
kml help
kml --help
kml -h
kml check --help

# Localized help
kml --locale ja help

# Show version aliases
kml version
kml --version
kml -v

# Fix and Format
kml fix README.md
kml fmt

MCP server entrypoints

Use kml-mcp for local stdio MCP clients:

uvx --from katana-markdown-linter==0.19.3 kml-mcp --workspace-root /absolute/path/to/workspace

Use kml-mcp-remote only for self-hosted Streamable HTTP:

KML_MCP_REMOTE_TOKEN=change-me \
  uvx --from katana-markdown-linter==0.19.3 kml-mcp-remote

Supported Platforms

The Python launcher uses the same binary archives as the GitHub Release channel. It currently supports:

• macOS arm64: aarch64-apple-darwin
• macOS x64: x86_64-apple-darwin
• Linux x64: x86_64-unknown-linux-gnu
• Windows x64: x86_64-pc-windows-msvc

Unsupported platforms fail before download with an explicit platform error.

Wrapper Contract

• The package version selects the GitHub Release tag.
• The launcher downloads the matching kml-vX.Y.Z-<target>, kml-mcp-vX.Y.Z-<target>, or kml-mcp-remote-vX.Y.Z-<target> archive.
• The launcher downloads the matching .sha256 file and verifies the archive before extraction.
• The installed binary is cached by version, platform, and executable role.
• MCP launchers do not write wrapper logs to stdout, preserving JSON-RPC stdio.
