Good to know

A few practical details.

Waiting for IT approval?Use the LLM Bundle while your team reviews MCP.

Open Prospect Hub, choose an account, download the LLM Bundle, and attach it to Claude, ChatGPT, or another approved model. It includes the account thesis, stakeholder context, technology signals, and suggested angles.

Open Prospect Hub Review security posture
Security & accessRead-only account intelligence, authenticated with ATC.

The ATC MCP server gives Claude or ChatGPT access to ATC account intelligence over HTTPS. Users authenticate with ATC through OAuth. ATC is not in the path of your normal chat traffic and does not receive your prompt stream.

Read-only retrieval

The connector retrieves ATC account intelligence. It does not write to your CRM, email, warehouse, or internal systems.

Prompts are not routed through ATC

ATC is not a prompt proxy. Claude or ChatGPT calls ATC tools only when you enable the connector for account intelligence.

OAuth with ATC login

Users authenticate through ATC's OAuth flow, so access is tied to an ATC account and can be governed through normal admin controls.

Scoped account resources

Tools return only the ATC resources needed for Account Attack Plans, such as briefs, stakeholders, technographics, and angles.

Need a hand connecting?Workspace permissions, authentication, and common setup questions.
I do not see Add custom connector in Claude

You may be on a Team or Enterprise workspace where an Owner must add the connector first.

I do not see Create in ChatGPT

Developer mode or custom apps may not be enabled for your account or workspace.

Authentication fails

Confirm you are using the ATC account tied to your workspace and that your browser allows the auth redirect.

The connector appears, but tools are missing

Refresh connector metadata in ChatGPT, or remove and re-add the connector in Claude.

Claude or ChatGPT cannot reach the server

The MCP server must be publicly reachable over HTTPS. Confirm the endpoint is live and not blocked by firewall rules.
