Signing In
Connect the OpenGraph MCP Server however suits you best — sign in with your account, or use an API key. Both work with the hosted server at https://mcp.opengraph.io/mcp.
Sign in with your account
Most clients (Cursor, VS Code with the MCP extension, Windsurf, JetBrains, and others) connect to the hosted server by adding this to their config file, with no credentials to copy:
{
"mcpServers": {
"opengraph": {
"url": "https://mcp.opengraph.io/mcp"
}
}
}You'll be prompted to sign in through your browser once, and the client remembers you after that.
Claude Desktop is different: it doesn't support adding remote servers by editing a config file. Add OpenGraph.io via Settings → Connectors → Add custom connector instead — see the Claude Desktop guide for the exact steps.
- No API key to copy or store in a config file
- Required for the Site Audit and Link Preview tools
- Works alongside your existing dashboard login
Use an API key
Prefer a static config, or using a client that doesn't support sign-in yet? Add your App ID as a header instead:
{
"mcpServers": {
"opengraph": {
"url": "https://mcp.opengraph.io/mcp",
"headers": {
"x-app-id": "YOUR_OPENGRAPH_APP_ID"
}
}
}
}Don't have an App ID? Get one free → or visit the Install Hub for ready-made configs for every client.
Claude Desktop's connector UI is sign-in only and doesn't support a static App ID header. To use a static App ID with Claude Desktop, run the server locally via npx instead — see the Claude Desktop guide.
Which one do I need?
| Tool Group | API Key | Sign In |
|---|---|---|
| Web data (fetch, scrape, screenshot, markdown, extract, query) | Yes | Yes |
| Image generation | Yes | Yes |
| Site Audit & Link Preview | — | Yes (required) |
Site Audit and Link Preview bill against your organization's plan rather than a single API key, so those tools need you to sign in. Learn more →
