## 🔥 What is REAL WebMCP?

**WebMCP** (Web Model Context Protocol) is a **new browser standard** from Google and Microsoft that went live in **Chrome 146 Canary (Feb 2026)**.

It's **NOT** the same as Anthropic's MCP:

| | Anthropic MCP | WebMCP (Real) |
|---|---|---|
| **Where** | Server-side | Browser client-side |
| **Transport** | JSON-RPC | `navigator.modelContext` API |
| **Auth** | OAuth 2.1 | Browser cookies/SSO (inherited) |
| **By** | Anthropic | Google + Microsoft (W3C) |
| **When** | Nov 2024 | Feb 2026 |

## 🏛️ Two WebMCP APIs

### 1. Declarative API
HTML forms with tool attributes:
```html
<form data-webmcp-tool="searchProducts">
  <input name="query" placeholder="Search...">
  <button type="submit">Search</button>
</form>
```

### 2. Imperative API
JavaScript tool registration:
```javascript
navigator.modelContext.registerTool("bookFlight", {
  parameters: { origin: "string", destination: "string" }
}, async (params) => {
  // Tool execution logic
});
```

## 🚀 Deploy Real WebMCP

### Step 1: Deploy Updated Code
```bash
# On VPS
ssh root@arif-fazil.com
cd /root/arifosmcp
git pull origin main
docker-compose up -d --build arifosmcp
```

### Step 2: Verify WebMCP Works
```bash
# Check manifest
curl https://arifosmcp.arif-fazil.com/.well-known/webmcp

# Check console
curl https://arifosmcp.arif-fazil.com/webmcp

# Check SDK
curl https://arifosmcp.arif-fazil.com/webmcp/sdk.js
```

### Step 3: Test in Browser
1. Open Chrome 146+ (or any browser)
2. Go to: https://arifosmcp.arif-fazil.com/webmcp

## 🆚 ACLIP-CAI vs WebMCP

| | ACLIP-CAI | Real WebMCP |
|---|---|---|
| **Purpose** | AI agent console | Human browser interface |
| **Port** | 8081 | 8080 (same as MCP) |
| **Route** | Was `/webmcp` (wrong!) | Now `/webmcp` (correct!) |
| **Audience** | AI agents (Kimi, Claude) | Human users |
| **Auth** | API keys | Browser cookies/SSO |

**What changed:**
- Removed wrong WebMCP route from aclip-cai (port 8081)
- Added Real WebMCP to arifosmcp (port 8080)
- Now `/webmcp` serves the actual W3C standard WebMCP

## 🎯 Quick Test

```bash
# 1. Check if WebMCP is discoverable
curl -s https://arifosmcp.arif-fazil.com/.well-known/webmcp | jq

# Expected output:
{
  "schema_version": "1.0",
  "site": {
    "name": "arifOS Constitutional AI",
    "version": "2026.03.14-VALIDATED"
  },
  "apis": {
    "declarative": true,
    "imperative": true
  }
}

# 2. Check console page
curl -s https://arifosmcp.arif-fazil.com/webmcp | head -20

# Should show HTML with "arifOS WebMCP" title
```
