Sync GTM MCP Server

The Sync GTM Model Context Protocol (MCP) server lets AI assistants — Claude Code, the Claude app, Claude Cowork, Cursor, Codex, ChatGPT, Gemini CLI, OpenClaw, and Manus — interact directly with your Sync GTM workspace.

With the MCP server, AI agents go beyond chat: they enrich people and companies, find verified emails and phone numbers, pull LinkedIn data, and read buying signals — all with full awareness of your workspace context.

The server endpoint is:

https://api.syncgtm.com/mcp

Authentication

Sync GTM’s MCP server uses secure browser-based sign-in (OAuth). There is no API token to copy or paste and no Authorization header to configure.

The first time your client connects to https://api.syncgtm.com/mcp, it opens your default browser to the Sync GTM authorization page. Sign in to your Sync GTM account and approve the connection — your client then stores the session and reconnects automatically.

Tip: Make sure you’re already signed in to the Sync GTM app in your default browser. The authorization page opens there.

Prerequisites

  • A Sync GTM account — sign up free
  • One supported MCP client (see the grid above)
  • For browser sign-in: be logged in to Sync GTM in your default browser

Tools

The server exposes 20+ enrichment, contact-discovery, LinkedIn, and signal tools. See the full list with credit costs on the Tools page.

Usage

Once connected, use natural language to drive your Sync GTM workspace — including batch workflows over your own lists. Example prompts:

  • “Find work emails for all the leads in this CSV”
  • “Find the LinkedIn URL of every lead in my list”
  • “Get the latest LinkedIn posts for these profiles and analyze them”
  • “Enrich these company domains and pull their tech stack”
  • “Find people in sales roles at this company”
  • “Verify these email addresses and flag the invalid ones”
  • “How many credits do I have left?”

Troubleshooting

Sign-in issues

  • If the browser sign-in window doesn’t open automatically, trigger it manually — run /mcp in Claude Code, or click Authorize / Sign in / Needs login in your client’s MCP settings.
  • Make sure you’re signed in to the correct Sync GTM workspace in your default browser.
  • If you get a 401 Unauthorized after some time, your session may have expired. Reconnect and sign in again.

Connection issues

  • Ensure your network allows outbound HTTPS requests to api.syncgtm.com.
  • Restart your MCP client after editing its configuration.

Tools not appearing

  • Restart your MCP client.
  • Verify the Sync GTM server is listed and shows as connected / authenticated in your client’s MCP settings.

Security

  • Authentication uses OAuth browser sign-in — your password is never shared with the MCP client, and there is no long-lived API token that can leak.
  • All communication uses HTTPS encryption.
  • You can revoke a client’s access at any time from your Sync GTM dashboard.
