Use Prospect Hub and the LLM Bundle while IT reviews MCP

If your team needs approval before adding MCP, you can still use ATC in the browser. Open Prospect Hub, choose an account, download the LLM Bundle, and attach it to Claude, ChatGPT, or another approved model. The bundle gives the model account-specific GTM judgment without installing a connector.

Instead of starting from generic account research, the model starts with ATC's fit, stack interpretation, driver and blocker logic, buyer sequencing, and account-specific message hooks.

First prompts

Your first ATC prompts

Start with account prioritization, an Account Attack Plan, outbound drafts, or meeting prep grounded in ATC intelligence.

Prompt 01

Using ATC, rank the accounts I should call first this week. For each account, return the thesis, urgency signal, buying center, likely pain, and next action.

Prompt 02

Build an Account Attack Plan for [ACCOUNT] as a seller at [MY COMPANY]. Include the problem thesis, key personas, active initiative, stack context, and outreach angle.

Prompt 03

Draft three outbound emails to [PERSONA] at [ACCOUNT] using ATC intelligence. Make each message specific, concise, and tied to the account's current motion.

Prompt 04

Before my meeting with [ACCOUNT], give me the account thesis, likely objections, buying committee, technical angle, and discovery questions.

Security

Read-only, OAuth-authenticated access

The ATC MCP server is a read-only way for Claude or ChatGPT to request ATC account intelligence over HTTPS. It is not in the path of your normal chat traffic, does not receive your prompt stream, and does not connect to your internal systems.

Users authenticate with ATC through OAuth. Once enabled, the connector can return only the scoped ATC resources needed to generate Account Attack Plans: account briefs, stakeholder context, technographics, drivers and blockers, and angles of approach.

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.

Troubleshooting

Common install issues

Most connector issues come down to workspace permissions, developer-mode availability, authentication, or stale connector metadata.

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.
