Been sent a .moca file?

Open it in your AI assistant: one download connects it to Claude Desktop, Claude Code, VS Code or Cursor, and every answer cites its source. No code needed.

Using an AI assistant?

Add the openmoca agent skill to Claude, GitHub Copilot or Codex first. Then ask it to make, sign, search and cite packages for you.

Pick a language. Each guide takes about ten minutes: install the Reader, open a signed example package, search it and cite what you find, then run the conformance corpus that every MOCA Reader passes. Each guide is run as written in its Reader’s CI.

TypeScript and JavaScriptThe reference Reader, @openmoca/moca-core. Node.js 22 or later.

.NETOpenMoca.Reader, with bindings for Microsoft.Extensions.AI, the Agent Framework and VectorData. .NET 10.

Not writing code?

• Try OpenMOCA: search real packages and open every result at its source, in the browser, with no account.
• Quickstart: make a package from Markdown and check it.
• Got a .moca file?: ask Claude Desktop, Claude Code, VS Code or Cursor about it, with one download.
• MCP server: one download that gives any MCP client search and citations over your packages.
• Walkthrough: check, sign, review, index and serve a package to an AI agent, step by step.

Example packages

Each example is one .moca file from the latest specification release. A Reader opens the file just as it opens a folder.

Example	What it shows	Download
Minimal package	The smallest valid package: a manifest and one page	minimal
Support knowledge base	Signed and reviewed, two languages, an internal page, and quotes checked against the source terms	support-kb, and the trust root to verify it
Acme Support Knowledge Base	34 pages in English and French: internal procedures, old and future policies, stale and disputed pages, reviews and a topic structure. The walkthrough uses it	acme-support
Policy corpus	Two versions of a policy, each with a validity window, the second superseding the first	1.0.0, 2.0.0
Composed handbook	A handbook built from two chapter packages, each pinned by its digest	handbook, and its chapters incident response and service ownership
PDF manuals	The FAA’s Airplane Flying Handbook, converted from 19 PDFs, cited to the page	airplane-flying-handbook
YouTube videos	A recorded talk and a playlist, cited to the moment	talk, playlist

They are also in the moca-spec repository as folders, with how each was made.
