    Get a Sellinger workspace

    Start the free trial (30 days, no card), or use the workspace you already have.

    In claude.ai or the Claude desktop app, open Customize, then Connectors (older builds: Settings, then Connectors). Click Add custom connector and paste the URL below. Leave client ID and secret empty.

    Switch it on in a chat

You stay in control

Powerful when you want it. Read only when you don't.

  • OAuth, no API keys in chat

    You sign in to Sellinger; Claude never sees a password or key.

  • Read only, if you want

    Read only lists and reads everything: no sends, no writes, no approvals.

  • Every request logged

    Connector calls are audit logged. Disconnect any time and access ends at once.

  • Short-lived tokens

    Access tokens last 8 hours and refresh for up to 90 days, scoped to one workspace.

Questions

Building your own integration? See the MCP and API overview.

Do I need a Sellinger account?
Yes. The connector works inside your Sellinger workspace, where your leads, agents and conversations live. Start with the 30-day free trial; no card needed.
Does it work with ChatGPT?
Yes. Use the same URL through ChatGPT's connectors and developer mode. Any MCP client that supports the streamable HTTP transport with OAuth can connect the same way.
Is Sellinger in the Claude connector directory?
Not today. You add it as a custom connector with the URL on this page, which takes about a minute.
We are on Claude Team or Enterprise. Who adds it?
Only an organization Owner (or Primary Owner) can add a custom connector, under Organization settings, then Connectors. It is added once per organization; each member then connects their own Sellinger account under Customize, then Connectors. Send your Claude admin the URL on this page.
Can Claude send messages for me?
With Full access, yes: it can send messages, update leads and approve outreach when you ask it to. With Read only it can look at everything but change nothing.
What exactly can it do?
43 tools across leads, prospecting, conversations, campaigns, approvals, meetings, analytics, personas and search, plus 4 saved workflows: weekly pipeline review, prep my day, find new prospects and audit stale leads.
Is my data used to train AI models?
Sellinger does not use your data to train AI models. Traffic runs over HTTPS and tokens are scoped to one workspace and one access level.
