Cursor

How to connect ZoomInfo MCP to Cursor using the mcp-remote bridge, which handles the browser OAuth sign-in and exposes ZoomInfo to Cursor's Agent.

Overview

Cursor supports custom MCP servers, so you can give Cursor's Agent live ZoomInfo data alongside your code. Cursor connects to ZoomInfo through the mcp-remote bridge: a small local proxy (run via npx) that handles the browser sign-in and exposes ZoomInfo to Cursor over stdio. There is no developer app to register and no client secret to paste; you sign in with your normal ZoomInfo credentials on first use.

Requirements

Node.js 18 or later with npx on your PATH. Check with node --version. If you don't have it, install from nodejs.org↗ or via your package manager.

Setup

Open your MCP config

In Cursor, go to Settings → Cursor Settings → Tools & Integrations and open the MCP configuration, or edit ~/.cursor/mcp.json directly.

Add the ZoomInfo server

Add the zoominfo entry to your mcpServers block:

json

// ~/.cursor/mcp.json
{
  "mcpServers": {
    "zoominfo": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote@0.1.38",
        "https://mcp.zoominfo.com/mcp",
        "46818",
        "--static-oauth-client-metadata",
        "{\"scope\":\"openid profile email offline_access zi_api zi_mcp api:data:mcp\"}"
      ]
    }
  }
}

Restart Cursor

Restart so Cursor picks up the new server entry.

Authenticate

The first time Cursor uses the server, the bridge opens the ZoomInfo sign-in in your browser. Log in with your normal credentials or SSO and approve access. On success you'll land on a page reading "Authorization successful! You may close this window and return to the CLI" (the address bar will show localhost:46818). Close the tab and return to Cursor.

Tokens are cached locally under ~/.mcp-auth/, so you won't be prompted again until they expire. If Cursor still shows the server as connecting, toggle the MCP server off and on (or restart Cursor) so it picks up the authenticated bridge.

Verify the connection

Open the Agent and ask: "How many employees does Snowflake have?" A healthy connection calls the matching ZoomInfo tool and returns live data.

Next - run your first session. Once the ZoomInfo server is authenticated, paste this into Cursor's Agent. It orients from your GTM context and only runs after you approve:

First GTM session

(Use the ZoomInfo MCP tools if available; otherwise use the GTM CLI.)

I just connected ZoomInfo. Help me get real value from my ZoomInfo credits today - I want to spend them on the most valuable first thing to do. Don't run anything I haven't picked yet.

1. Call get_gtm_context - it's free (no credits). Use whatever it returns, plus my company name and email domain, to work out what we sell and who we target. Don't ask me, just figure it out.

2. Say it back in one line: "You're <Company>, selling <offering> to <ICP>." Check I agree. Once I confirm, save it by calling update_gtm_context so my GTM context is set for next time. If I'm not an admin, the save will fail - that's fine, just continue.

3. Offer me 3–4 concrete first actions grounded in my context - e.g. prep for a meeting this week, find companies matching our ICP, surface accounts showing buying intent, map the buying committee at a target account. Let me pick one, or tell you my own goal.

4. Only once I've chosen: tell me which ZoomInfo tools you'll run and roughly how many credits it'll cost. Go ahead - that's what they're for. Just tell me the cost before running so I stay in control.

Keep it fast. A quick, real win - not a tour and not a list I didn't ask for.

How Cursor Selects Tools

Cursor's Agent reads the ZoomInfo tool descriptions and picks the right tool for your request. You don't need to name a tool, though you can reference ZoomInfo explicitly to steer it. Ask it to "research Acme Corp" and it invokes Account Research; ask for VPs of Sales at companies like Salesforce and it chains Find Similar Companies into Search Contacts.

Direct tools (Search, Enrich, Lookup) return data straight into the Agent's context window, so narrow your filters before searching across thousands of records. Research tools synthesize large payloads before returning a summary, which keeps context manageable.

Troubleshooting

"Failed during live tool discovery" or the server errors immediately after you add it: this usually means Cursor was configured with a native { "url": "..." } entry instead of the bridge. Use the mcp-remote bridge config shown in Setup above, then restart Cursor.

npx or "command not found" errors: the bridge requires Node.js. Confirm node --version returns 18 or later and that npx is on your PATH, then restart Cursor.

Authentication never completes or times out: make sure you're signing in with your personal ZoomInfo credentials, not a shared or admin-only account. If the browser window didn't open, or the token has gone stale, toggle the server off and on to re-trigger the OAuth flow. You can also clear the cached tokens under ~/.mcp-auth/ and reconnect to force a fresh sign-in.

The server shows as disconnected: confirm the JSON in ~/.cursor/mcp.json is valid (a trailing comma is the usual culprit) and that the endpoint is exactly https://mcp.zoominfo.com/mcp. Restart Cursor after any edit.

No tools appear: open the MCP settings and confirm zoominfo is enabled. Cursor refreshes the tool list when it reconnects to the server.

Credit errors during enrichment: MCP requires bulk data credits. Confirm with your ZoomInfo admin that your account has bulk credits enabled. Recurring monthly credits are not supported by MCP.
