Connect your AI tool

UGC Chart runs a remote MCP server. MCP is the standard way AI tools like Claude and ChatGPT connect to outside data. Add one link, sign in once, then just ask.

https://ugcchart.com/mcp

You need a work email. Sign up free while you connect. Personal emails like Gmail won’t work.

Claude (claude.ai and the Claude app)

1. Go to claude.ai. Open Settings, then Connectors.
2. Click Add custom connector.
3. Name it UGC Chart. Paste the link above.
4. Click Add, then Connect.
5. Sign in with your work email. Then click Allow.

ChatGPT

Use ChatGPT on the web.

1. Go to chatgpt.com/plugins.
2. Click the + button, then Add custom MCP server.
3. Name it UGC Chart. Under Connection, paste https://ugcchart.com/mcp as the Server URL.
4. For authentication, pick OAuth.
5. Read the warning and tick I understand and want to continue.
6. Click Create as a plugin, then Connect.
7. Sign in with your work email. Then click Allow.

To use it, type @UGC Chart in the chat box, then ask your question.

Using ChatGPT at work? Your admin may need to allow custom MCP servers first. We have also applied to ChatGPT’s app directory. Once we are approved, you will be able to add UGC Chart from there too.

Claude Code

Sign in and make a key on your account page. Then run this in your terminal. Swap ugc_... for your key.

claude mcp add --transport http ugc-chart https://ugcchart.com/mcp --header "Authorization: Bearer ugc_..."

Cursor and other MCP clients

Most clients that support remote MCP servers can connect with the link alone. They open a sign-in page the first time.

{
  "mcpServers": {
    "ugc-chart": { "url": "https://ugcchart.com/mcp" }
  }
}

If your client can’t open a sign-in page, use an API key instead. Make one on your account page and send it as a header:

Authorization: Bearer ugc_...

For developers: how sign-in works

• Transport: Streamable HTTP. The server is stateless. It answers POST /mcp with plain JSON.
• Auth: every request needs Authorization: Bearer <token>. Without it, /mcp answers 401 with a WWW-Authenticate header that points to our resource metadata.
• OAuth 2.1 with PKCE (S256 only) and dynamic client registration:
  • Resource metadata: https://ugcchart.com/.well-known/oauth-protected-resource/mcp
  • Server metadata: https://ugcchart.com/.well-known/oauth-authorization-server
  • Register: POST https://ugcchart.com/oauth/register
  • Authorize: https://ugcchart.com/oauth/authorize
  • Token: POST https://ugcchart.com/oauth/token
• Redirect links must be https, or http on localhost.
• Access tokens last 1 hour. Refresh tokens last 30 days and work once each.
• A token from sign-in can only read UGC Chart data. It can’t see your email or your lists, and it can’t change anything.
• Server card: https://ugcchart.com/.well-known/mcp/server-card.json
• Official MCP Registry name: com.ugcchart/ugc-chart
