Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://open-to-close.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http open-to-close https://open-to-close.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "open-to-close": {
      "url": "https://open-to-close.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Open To Close credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/open-to-close/

Generate an API token in the Open To Close Apps & API Dashboard. Usage and billing are per API token. The integration can read transaction records and, when requested, create contacts and property notes.
