Show HN: An MCP server that turns async-work practices into tools

A developer has released an open-source Model Context Protocol (MCP) server that turns async-work practices from the book 'Open and Async' into AI-accessible tools, enabling users to draft decision docs, convert meetings to async artifacts, score status updates, and triage sync-vs-async debates directly from editors and AI assistants. The server, available via npx as @open-and-async/mcp, provides 10 tools including a 'coach' prompt that generates a complete async deliverable for a given situation, with all reference tools citing the book's publicly available summaries.

Bring async-first working practices into your editor and AI assistant. This Model Context Protocol server gives your AI the tools to draft a decision doc, turn a meeting into an async artifact, pressure-test a status update, or settle a sync-vs-async debate β€” without leaving the tools you already work in.

It's the method from ** Open and Async** β€” the collaborative software-development playbook for remote and distributed teams β€” as working tools, not reading.

Stop writing decision docs from a blank page. Hand your AI the decision and the options; get back a structured ADR scaffold β€” context, tradeoffs, the call, and how reversible it is.Turn "let's hop on a call" into an artifact. Give it a meeting's purpose and agenda; get the async equivalent with an owner and a deadline.Ship status updates that don't blindside anyone. Score a draft against the "work loudly / no surprises" rubric and get concrete fixes before you post it.Settle sync vs. async in seconds. Describe the task; get a recommendation and the rule behind it.Run a standup without a meeting. Drop in a structured async-standup template your team can adopt today.Win the "async is too slow" argument. Map common objections to a ready reframe, pull role-aware guidance, or search the book's principles β€” each answer cited and linked.Get coached end to end. Run thecoach

prompt with a situation and it triages sync vs. async, generates the right artifact, adds role guidance, and caps with a shareable line β€” one composed answer, or a nudge to just have the conversation when that's the better call.

Claude Code:

claude mcp add open-async -- npx -y @open-and-async/mcp

Claude Desktop (claude_desktop_config.json

):

{
  "mcpServers": {
    "open-async": {
      "command": "npx",
      "args": ["-y", "@open-and-async/mcp"]
    }
  }
}

Any MCP client that speaks stdio works the same way: run npx @open-and-async/mcp

.

Tool What it does
draft_decision_doc
Decision + options β†’ a structured ADR/decision-doc scaffold (context, options, tradeoffs, decision, reversibility).
convert_meeting_to_async
Meeting purpose/agenda β†’ the async equivalent (artifact, owner, deadline).
score_status_update
Scores a draft update against the "work loudly / no surprises" rubric and suggests fixes.
run_async_standup
A structured async-standup template a team can adopt.
triage_sync_vs_async
Recommends sync vs async for a task, with the decision rule.
Tool What it does
book_outline
Sections + chapters + one-line TL;DRs. The map.
get_chapter_summary
A chapter's TL;DR + taglines + read-the-chapter link.
search_principles
Keyword search over the summary corpus; short cited snippets.
handle_objection
Maps skepticism ("async is slow") to the book's reframe.
get_guidance
Role-aware (manager /ic ) guidance for a topic.
get_taglines
Taglines + their /q/<slug> quote-card URLs.

book://outline

β€” sections, chapters, TL;DRs (JSON)book://taglines

β€” taglines + quote-card URLs (JSON)book://about

β€” what this server is, what it does and doesn't contain, and where to get the book

Invoke these directly from your client (e.g. as slash commands):

coach

β€”the full method on one situation. Triages sync vs. async, generates the right artifact, enriches with role guidance, and caps with a shareable tagline β€” one composed deliverable. Stops and recommends a real-time conversation when the situation genuinely needs one.async-standup

,write-adr

,meeting-to-issue

,weekly-update

β€” parameterized templates for a single task.

It's a real tool, not a paywall. The method tools work on their own β€” no book required. The reference tools answer from the book's already-public summaries and a paraphrased framework layer, always capped and always cited so you can trace any snippet to its chapter. The "get the book" link surfaces about once per session, not on every line β€” it's a tool, not an ad. No verbatim book prose is bundled (the only data file is data/book.json.br

), so what you install is genuinely useful, not a teaser.

Staying current. data/book.json.br

ships with a version

that tracks the book's edition, so the server can tell you which edition it's based on and re-sync when a new one lands.

Generated output is a template, not the author speaking. The method tools format your input into decision docs, standups, and triage calls. That output is generated guidance to adapt β€” it is not a personal statement, quote, or endorsement by Ben Balter or Open & Async LLC, and shouldn't be presented as one. Reference-tool snippets are summaries the tool cites back to the book, not verbatim prose.
