Connect OnePageCRM without code

OnePageCRM's docs confirm it works in Claude and ChatGPT. You don't need a terminal or a config file. Check OnePageCRM's docs first: some vendors give you a personal URL or an API key to use in place of the plain endpoint.

Claude (web and desktop app)

If OnePageCRM shows up when you browse connectors in Claude, connect it from there instead. That skips steps 2 to 4.

  1. In Claude, open Customize → Connectors.
  2. Click + Add, then Add custom connector.
  3. Name it “OnePageCRM”, paste the server URL https://app.onepagecrm.com/mcp, and click Continue.
  4. Review the sign-in settings Claude detected and click Add.
  5. Click Connect and sign in to OnePageCRM. Then ask Claude something like “What can the OnePageCRM connector do?”

On Team and Enterprise plans, an Owner adds the connector first under Organization settings → Connectors → Add → Custom → Web. Each person then connects it from Customize → Connectors. Free plans can add one custom connector.

ChatGPT

If OnePageCRM has its own plugin in ChatGPT's directory, install that instead.

  1. Go to chatgpt.com/plugins.
  2. Select +, then Add custom MCP server. If you don't see it, your plan or workspace settings may not allow custom servers, so ask your workspace admin.
  3. Enter a name and description. Under Connection, paste the server URL https://app.onepagecrm.com/mcp.
  4. Set up sign-in, read the warning, and select I understand and want to continue.
  5. Select Create as a plugin. In a new chat, type @ and pick OnePageCRM.

From OnePageCRM's docs: Add https://app.onepagecrm.com/mcp, sign in, and approve the consent screen. Allow AI access (MCP) and View CRM data are required. View and update CRM data is optional. Without it, the connection cannot change records. Focused users cannot connect. Claude Code uses claude mcp add --transport http, then /mcp.Source: developer.onepagecrm.com, checked 2026-11-02

Developer setup (Claude Code, Cursor)

Add this to .mcp.json (Claude Code, project root) or ~/.cursor/mcp.json (Cursor). Remove the // comment line if your client requires strict JSON.

{
  "mcpServers": {
    "onepagecrm": {
      "url": "https://app.onepagecrm.com/mcp"
    }
  }
}
  1. Add the endpoint to your client config (above), or as a custom connector in Claude.
  2. Complete the OAuth sign-in. In Claude Code, run /mcp and pick the server.
  3. Test it with a prompt like: “List the tools the OnePageCRM MCP server exposes.”
