# ARC, readable by your agent.

> Read ARC's public content, draft recovery operations articles and case studies, and review drafts in an MCP Apps-compatible client. Public reading needs no sign-in; private authoring uses OAuth, server-side quality checks and explicit publishing approval. Drafts stay private to their authors, and every published answer has a permanent Markdown twin.

## Public reading needs no sign-in.

Agents can search the site, read published pages and list articles. Every public page also has a Markdown twin for answer engines and coding agents.

### Connect

Point an MCP-compatible client at ARC's streamable HTTP endpoint.

### Search and get_page

Find approved public answers, articles and case studies. Private drafts and build indexes are never exposed.

### start_post to publish_draft

Listed authors use OAuth to draft from real work, run deterministic lints and server-side checks, then approve publication.

### An MCP App for drafts

Compatible clients can render the draft preview, review checks and open publishing controls without giving the app direct network access.

## The content stays governed.

The MCP server never lets an author's agent grade its own draft. Heddle runs the publish checks on the saved bytes. Publishing needs an explicit confirmation, and the default is a pull request for a person.

### Before author sign-in works

- Create the D1 draft store and OAuth KV namespace
- Configure Microsoft Entra or another OIDC provider
- Add each author's email in heddle/people.json
- Set the OAuth and job secrets on the Worker
