🖼️ Multimodal Support

The documentation has been optimized for AI agents with "vision" capabilities.

• Remote Images: All diagrams and screenshots are linked directly to the official Gitee repository.

• Agent Action: Multimodal agents can follow these links to download and analyze visual architecture diagrams, UI mockups, and flowcharts to provide more accurate explanations.

🌐 Understanding the Two Modes

1. Stdio Mode (Default)

Used by local assistants (Claude Desktop, Cursor, etc.). The assistant starts the server as a background process.

2. HTTP Mode

Use this for remote access or web integrations.

# Start server
npx -y github:megaacheyounes/ohos-mcp-unofficial --http --port 3456

• Health Check: http://localhost:3456/health

• Tool Calls: POST to http://localhost:3456/call

🧰 Available Tools

• find_docs: Search documentation by keywords (e.g., "Navigation", "Canvas").

• read_doc: Retrieve the full Markdown content of a specific document.

• list_doc_topics: Browse the documentation hierarchy.
