Use Contiguity’s MCP server to give AI agents — in Cursor, Claude, ChatGPT, and more — the ability to send messages, emails, configure your account, and lease numbers on your behalf. The server is hosted at console.contiguity.com/mcp and uses OAuth to authenticate with your Contiguity account.

​
How it works

When you connect a client, you’re taken through a OAuth flow that links the session to your Contiguity account. After authorization, the client receives a short-lived token that it uses on every tool call. All requests are proxied to the Contiguity API and billed against your existing account quota.
On some plans, Contiguity may bill you for using the API via MCP. Confirm pricing at contiguity.com/pricing.

​
Quick connect

Add to Cursor

One-click install. Cursor will open an OAuth flow to connect your account.

Add to Claude

Click “Add custom connector,” enter the MCP server URL, and login. Click “Add” to finish setup.

Add to ChatGPT

Go to Settings → Apps → Advanced, enter the name and URL, then click Auth to connect.

​
Setup by client

Click the Add to Cursor button above, or follow these steps manually:
1

Open MCP settings

In Cursor, go to Settings → Tools & MCP → New MCP Server.
2

Add the server

Paste this into your mcp.json:
{
  "mcpServers": {
    "contiguity": {
      "url": "https://console.contiguity.com/mcp"
    }
  }
}
3

Authenticate

Cursor will detect the server and prompt you to sign in with GitHub via your Contiguity account. Approve the OAuth request.
4

Start using it

Open Cursor’s agent and try: “Send an SMS to +1 555 000 1234 saying hello.”
