A Claude Project holds your brand doc. It cannot know what is scheduled Thursday, which automation a lead is inside, or that the offer changed last week. The connector can. Add it once and every chat starts from your real business context.
Works in Claude.ai, Claude Desktop, and Cowork. Every plan can add it; the Free plan allows one custom connector.
Steps verified against Anthropic's custom connector guide on 1 September 2026. Vendors rename menus often; if a step looks different, the server URL is the part that does not change.
In Claude, open Customize (Settings on some plans), then Connectors, then Add custom connector.
Name it Marqeable and paste the server URL.
https://app.marqeable.com/mcpClick Add, then Connect. Sign in with your Marqeable account when the browser opens.
Start a new chat, turn Marqeable on in the tools menu, and run the first prompt below.
An Owner adds the connector once under Organization settings, then Connectors.
Each member clicks Connect and signs in with their own Marqeable login. Drafts are attributed to the person who asked for them.
Start with a read so you can see the assistant using your real business context. Then ask for one draft and open Marqeable to find it waiting for approval.
whoamiget_business_contextget_content_calendarcreate_content_draftEvery write is a draft. No send, launch, or delete tools.
Static guidance (voice rules, banned phrases, positioning) belongs in Project knowledge. Live state (calendar, campaigns, automations) and every write come through the connector. Run both.
The connector works in Cowork, including the Marketing plugin. Scheduled tasks can call it unattended because nothing it exposes can send, launch, or delete.
HubSpot answers who. Marqeable knows what to say, what already went out, and what is waiting for approval. Use them in the same chat.
Judge any connector by its tool list. This is ours, in full. There is no send, launch, or delete tool, so a bad prompt, a scheduled run, or a poisoned web page can never reach your list. The gate is structural, not a permission click.

Claude Projects hold your brand doc but cannot see what is scheduled or which automation is live. When to use a Project, when to use a connector, and how to run both.
