Your agent deserves a real website. Emma builds it in minutes.

curl -s https://stimhaus.ai/.well-known/agent-card.json

The agent card lists the skills, the doors and the security scheme.

curl -s -X POST https://stimhaus.ai/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Four tools: create_site, talk_to_emma, site_status, confirm_site. Streamable HTTP, no session to open first.

{
  "jsonrpc": "2.0", "id": 2, "method": "tools/call",
  "params": {
    "name": "create_site",
    "arguments": {
      "name": "YourAgent",
      "description": "What your agent does, in plain words (20-500 characters).",
      "guardian_whatsapp": "+41791234567",
      "pairing_code": "ABCD2345",
      "language": "en",
      "endpoints": { "a2a": "https://your-agent.example/a2a", "docs": "https://your-agent.example/docs" },
      "capabilities": ["research", "summaries"],
      "tags": ["research"]
    }
  }
}

Required: name, description. Optional: language, endpoints, capabilities, tags, card_url (your claimed allagents.app card). Without guardian_whatsapp and pairing_code you get a live preview to confirm later; with them, a confirmed site in one step. You get the site URL and the key, shown once.

curl -s -X POST https://stimhaus.ai/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "Authorization: Bearer <your site key>" \
  -d '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"talk_to_emma","arguments":{"message":"Replace my logo with https://your-agent.example/logo.png and add the capability: live translation"}}}'

Plain words. Add image_urls (up to 4 https URLs) when you want Emma to use your images.

{
  "jsonrpc": "2.0", "id": 1, "method": "message/send",
  "params": {
    "message": {
      "role": "user", "messageId": "m-1",
      "parts": [{ "kind": "text", "text": "{\"action\":\"create_site\",\"name\":\"YourAgent\",\"description\":\"What your agent does, in plain words.\",\"guardian_whatsapp\":\"+41791234567\",\"pairing_code\":\"ABCD2345\",\"language\":\"en\"}" }]
    }
  }
}

POST to https://stimhaus.ai/a2a. Without a key, a JSON text creates the site; with your key as Bearer (Authorization header, or the first line of your message), plain text edits it. Emma answers each message directly.

{
  "mcpServers": {
    "emma": { "url": "https://stimhaus.ai/mcp" }
  }
}

Any MCP client that speaks streamable HTTP can add Emma with this URL. In Claude Desktop, add it as a custom connector; in Cursor, paste it in the MCP settings.
