G2 MCP endpoint and transport

https://mcp.g2.com/mcp

Transport: Remote HTTP (remote MCP server; transport name not stated in docs)
Docs: Official G2 MCP docs

Connect G2 without code

G2's docs confirm it works in Claude and ChatGPT. You don't need a terminal or a config file. Check G2'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 G2 shows up when you browse connectors in Claude, connect it from there instead. That skips steps 2 to 4.

In Claude, open Customize → Connectors.
Click + Add, then Add custom connector.
Name it “G2”, paste the server URL https://mcp.g2.com/mcp, and click Continue.
Review the sign-in settings Claude detected and click Add.
Click Connect and sign in to G2. Then ask Claude something like “What can the G2 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 G2 has its own plugin in ChatGPT's directory, install that instead.

Go to chatgpt.com/plugins.
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.
Enter a name and description. Under Connection, paste the server URL https://mcp.g2.com/mcp.
Set up sign-in, read the warning, and select I understand and want to continue.
Select Create as a plugin. In a new chat, type @ and pick G2.

Steps from the OpenAI developer docs: developers.openai.com, checked 2026-10-16

From G2's docs: Claude and ChatGPT install the G2 MCP connector from their directories; sign in to Claude with the email used for your G2 account. Microsoft Copilot (not GitHub Copilot) needs an Enterprise Copilot license. Direct/custom clients must register an OAuth app in the G2 Developer Portal because G2 does not support Dynamic Client Registration.Source: documentation.g2.com, checked 2026-10-16

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": {
    "g2": {
      "url": "https://mcp.g2.com/mcp"
    }
  }
}

Add the endpoint to your client config (above), or as a custom connector in Claude.
Complete the OAuth sign-in. In Claude Code, run /mcp and pick the server.
Test it with a prompt like: “List the tools the G2 MCP server exposes.”

G2 MCP authentication

OAuth 2.0 (Authorization Code with PKCE; pre-registered client, no DCR)

Sign in with OAuth in your client (run /mcp in Claude Code). Do it once interactively, and the client stores and refreshes the token.
