Claude Cowork
Connect Sync GTM to Claude Cowork, Anthropic’s desktop knowledge-work agent. Cowork runs inside the Claude desktop app and uses the same connectors, so you add Sync GTM once and it’s available in every Cowork session.
On a Claude Team or Enterprise plan? Custom connectors are controlled by your workspace admin — a member seat can’t add one. Ask your Claude admin to add Sync GTM (https://api.syncgtm.com/mcp) as a custom connector for the workspace, then each member authorizes it with their own Sync GTM account. On Pro and Max you can add it yourself.
Sync GTM uses browser-based sign-in (OAuth). There is no API key to copy or paste — leave the other fields empty and approve in your browser.
Why connect Claude Cowork to Sync GTM?
Cowork is built for deep, multi-step knowledge work — with Sync GTM connected, it can handle end-to-end GTM research and outbound prep in a single session:
- Prospect research in one session — “Research all decision-makers at my top 10 target accounts” and get enriched profiles back
- Account-based intelligence — tech stack, headcount trends, recent hires, open roles, LinkedIn activity — all in one canvas
- Draft outreach with real context — Cowork can find a contact, enrich their profile, and write a personalized message in the same task
- Track signals across accounts — job changes, hiring spikes, LinkedIn posts — surfaced automatically during research
- Build enriched lists for campaigns — generate ICP-matched lead lists with emails and mobile numbers, ready to export
Designed for sales teams, founders, and GTM operators who want a research agent that actually has access to live B2B data.

Step by step guide
Open Claude Cowork
Open the Claude desktop app (or claude.ai) and click the Cowork tab at the top.
Go to Customize
Click Customize in the left sidebar. You’ll see options for Skills, Connectors, and Browse Plugins.
Add Custom Connector
- Open Connectors and click Add custom connector
- Enter the server URL (field below)
- URL
https://api.syncgtm.com/mcp
- Click Add
Leave all other fields empty — Claude auto-discovers the server name and authentication settings.
Authenticate via Sync GTM
- Click Authorize — your browser opens the Sync GTM authorization page automatically
- Sign in to Sync GTM and approve — Sync GTM tools are now available in your Cowork sessions
Make sure you’re already signed in to the Sync GTM app in your default browser before authorizing — the authorization page opens there. No API token or header is required.
Notes
- A connector added in the Claude desktop app is shared with both Claude chats and Cowork.
- Custom connectors require a paid Claude plan (Pro, Max, Team, or Enterprise).
Managing more than one organization
Agencies and consultants often sit in several Sync GTM organizations — their own plus each client’s. The MCP connection is bound to the organization that was active when you authorized it. Switching organization in the Sync GTM app does not move the existing session across, so Claude Cowork keeps pulling the previous organization’s data and credits until you reconnect.
To work in a client’s account:
- Switch organization in the Sync GTM app — click the organization name in the top-left of the settings sidebar and pick the client’s organization.
- Open Customize → Connectors, find Sync GTM, and click Reconnect (or disconnect and connect again). Approve with the client’s organization active.
- Run
check_credits(free) to confirm which organization the session is now pointing at.
An endpoint to switch organization from inside the MCP server is on the way — until it ships, switch in the app and reauthenticate. Full detail in Working in a client’s organization.
