# How it works > How sight4agents builds agent-optimized websites, exposes them through native MCP, and routes every agent-proposed change through human review and approval before it goes live. sight4agents covers the whole lifecycle of a site: building it for people and agents, exposing it through MCP, and managing changes so agents can help while humans decide what goes live. ## 1. Build for people and agents Sites start from structured content. That content is rendered into fast, semantic, accessible HTML for people, and into Markdown, JSON, and structured data for agents. - Semantic HTML5 landmarks and a logical heading hierarchy - JSON-LD structured data (Schema.org) on every page - Markdown versions of every page, plus `llms.txt` and `llms-full.txt` - A sitemap, a JSON content index, and server-side search - Responsive layouts with light and dark themes ## 2. MCP-native by default Each site can expose a Model Context Protocol server. Agents connect over Streamable HTTP and use tools to work with the site directly: listing pages, reading content, and searching. Read-only tools are open to anyone. Tools that change content are designed to create proposals for review, not to publish directly. ## 3. Human-in-the-loop change management Agents are useful editors. They can fix typos, update outdated details, and draft new pages. But publishing is a decision for people. In sight4agents, every agent edit follows the same path: 1. **Propose**: An agent submits a change proposal with the edited content and a short explanation of why. 2. **Preview**: The proposal is rendered as a diff and a preview, so reviewers see exactly what will change. 3. **Review**: A person approves it, asks for revisions, or rejects it. Nothing is live yet. 4. **Publish**: Only approved changes are published. 5. **Record**: Every step is logged so changes can be traced and rolled back. ## Who does what - **Agents**: Read and search content, then draft and submit change proposals with reasons. - **Reviewers**: Inspect diffs and previews, then approve, request changes, or reject. - **Owners**: Decide who can review and publish, and can see the full history of every change. ## Want to try it? sight4agents is in early development.
