Charming MCP — Generate & Host Interactive Web Apps via AI Agents

Charming is a hosted MCP server that generates, hosts, and updates interactive web apps. Connect it to any MCP-compatible AI client and ask it to build an app — you get back a live URL in seconds. OAuth with Dynamic Client Registration is automatic — clients that support it show a one-time consent screen.

Think of it as "Vercel for agents" — your AI can go from idea to deployed interactive web app without touching a CLI, managing hosting, or configuring DNS.

What It Does

• App generation: AI agents describe an app and Charming builds + deploys it
• Live hosting: Every generated app gets a public URL immediately
• Iterative updates: Ask the agent to modify the app — Charming redeploys
• OAuth-native: No API keys to manage — Dynamic Client Registration handles auth
• Interactive apps: Full-stack web apps, not static pages

Key Tools

Tool	Description
charming_create_app	Generate and deploy a new interactive web app
charming_update_app	Modify and redeploy an existing app
charming_list_apps	List all apps created by this agent
charming_delete_app	Remove an app
charming_get_app_url	Get the live URL for an app

Quick Start

1. Add to MCP Client

{
  "mcpServers": {
    "charming": {
      "url": "https://api.charming.mcp.so/mcp"
    }
  }
}

2. First App

Once connected, just ask your agent:

"Build me a calculator app with a dark theme" "Create a markdown editor with live preview" "Make a poll/voting app for my team"

The agent calls charming_create_app, and Charming returns a live URL.

3. Iterate

"Add a history panel to the calculator" "Change the theme to match our brand colors"

The agent calls charming_update_app with the existing app ID.

Hermes Agent Integration

# ~/.hermes/config.yaml
mcp_servers:
  charming:
    url: "https://api.charming.mcp.so/mcp"

First connection triggers OAuth consent in your browser — one-time only.

Use Cases for Business Operators

1. Rapid prototyping: Describe a dashboard, CRM view, or data tool and get a working version in seconds
2. Internal tools: Build utility apps for your team without writing code — "make a PTO request form"
3. Client demos: Generate interactive demos during sales calls — "build a demo of what the analytics would look like"
4. Landing pages: Spin up event pages, waitlist forms, or micro-sites on demand
5. A/B test variants: Generate multiple page variants and iterate on winners

Limitations

• No custom domains (yet): Apps are served from Charming's domain
• No backend persistence: Apps are frontend-focused; persistent data requires external services
• Early stage: 9 GitHub stars as of July 2026 — feature set expanding
• Hosted only: No self-hosted option currently — apps live on Charming's infrastructure

Example: Building a Dashboard

User: "Build me a sales dashboard with a bar chart showing monthly revenue"

Agent → charming_create_app({
  name: "Sales Dashboard",
  description: "Monthly revenue bar chart with filters",
  requirements: "Bar chart, dark theme, responsive, month filter"
})

Charming → { app_id: "abc123", url: "https://abc123.charming.app" }

User: "Add a line chart for customer growth and make the background white"

Agent → charming_update_app({
  app_id: "abc123",
  changes: "Add line chart overlay for customer growth, switch to light theme"
})

Charming → { url: "https://abc123.charming.app" }  // Updated live

Category

Development — Charming bridges the gap between AI agent capabilities and deployed, interactive web applications. It's a "deploy target" for agents, similar to how Vercel is a deploy target for developers.
