Connect Crunchbase without code

Crunchbase's docs confirm it works in Claude and ChatGPT. You don't need a terminal or a config file. Check Crunchbase'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 Crunchbase 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 “Crunchbase”, paste the server URL https://mcp.crunchbase.com, and click Continue.
  4. Review the sign-in settings Claude detected and click Add.
  5. Click Connect and sign in to Crunchbase. Then ask Claude something like “What can the Crunchbase 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 Crunchbase 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://mcp.crunchbase.com.
  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 Crunchbase.
Steps from the OpenAI developer docs: developers.openai.com, checked 2026-10-16
From Crunchbase's docs: Claude: in the connector directory, including the free Claude plan; Team/Enterprise admins may need to enable connectors. ChatGPT: install from the plugin directory; Business/Enterprise/Edu admins control plugin availability. Claude Code picks up the claude.ai connector when signed in with a Claude.ai subscription (manual claude mcp add fallback). VS Code: Copilot Chat Agent mode only. Clients need CIMD support or a pre-registered OAuth client (DCR not supported).Source: data.crunchbase.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": {
    "crunchbase": {
      "url": "https://mcp.crunchbase.com"
    }
  }
}
  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 Crunchbase MCP server exposes.”
