Root README · Engine · MCP · GitHub

Install

npm install -g @markdownai/core
mai --version

Node 18+.

Subcommands

mai render <file>

Render a document to stdout (or -o <path>).

mai render docs/status.md
mai render docs/status.md --format ai --budget 4000
mai render skill.md --skill-args "audit auth" --skill-dir ~/.claude/commands

Flags: -o, --consumer, --format, --budget, --phase, --passthrough, plus the skill-render flags (--skill-args, --skill-dir, --skill-effort, --skill-session-id).

mai migrate-v2 <file> [--in-place]

Rewrite v1 directive syntax to v2. Delegates to packages/parser/scripts/migrate-v1-to-v2.mjs. Idempotent - re-running on a v2 file is a no-op.

mai migrate-v2 docs/old.md            # print diff to stdout
mai migrate-v2 docs/old.md --in-place # rewrite the file

Note: at the time of writing this subcommand may not yet be wired into the CLI. Until then, invoke the script directly: node packages/parser/scripts/migrate-v1-to-v2.mjs <file> --in-place

mai serve

Start the MCP server (stdio JSON-RPC). Used by Claude Code via mai init.

mai serve
mai serve --cwd /path/to/project --passthrough

See @markdownai/mcp for the 11 tools the server exposes and the multi-phase walk pattern.

mai validate <file>

Parse-only check. Exits 1 on errors. No directive execution, no IO.

mai validate docs/status.md
mai validate docs/status.md --strict   # warnings count as errors

Other commands

mai parse, mai eval, mai strip, mai build, mai watch, mai init, mai cache (show|clear), mai security (shell|http|db|filesystem|audit ...), mai list-phases, mai list-macros, mai list-imports. Run mai <command> --help for flags.

Universal flags on every command: --env <file>, --cwd <path>, --verbose, --strict, --silent.

Library usage

Every subcommand is also exported as a function:

import { runRender, runValidate, runServe, runStrip, runBuild, runInit } from '@markdownai/core'

const result = runRender('./docs/status.md', { format: 'ai', budget: 4000 })
console.log(result.output, result.exitCode)

Types: RenderOptions, RenderResult, ValidateOptions, ValidateResult, ParseCmdOptions, EvalOptions, StripCmdOptions, BuildOptions, InitOptions, ServeOptions, WatchOptions, HookDecision.
