What changesSame model. Account-specific intelligence.

Ask which accounts to call, why now, who owns the problem, and what your product should lead with.

ATC's models score the account before your AI sees it, so the answer starts from a forecast instead of a search.

01Create your ATC account

02Add the MCP endpoint

03Ask with ATC enabled

Setup paths

One account. Three ways to get moving.

Connect Claude, add ATC to ChatGPT, or keep working in Prospect Hub while your administrator reviews MCP access.

Path 01

Connect to Claude

Create your account, then add ATC as a Claude connector when your workspace allows custom connectors.

Start Claude setup

Path 02

Connect to ChatGPT

Create your account, then add ATC as a ChatGPT custom app when developer mode or custom apps are available.

Start ChatGPT setup

Path 03

Waiting for approval?

Use Prospect Hub and the LLM Bundle while your administrator reviews the connector details.

No MCP approval yet?

Keep moving 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

Start with work worth doing.

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

Prompt 01

Using ATC, who should I call this week, across both my saved accounts and new prospects?

Prompt 02

Build an Account Attack Plan for [ACCOUNT]. 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.

Prompt 05

Find accounts that look like [WON ACCOUNT] and tell me which ones have the most urgency right now.

Prompt 06

Before my QBR, show me what changed across my saved accounts in the last 30 days and which changes are worth acting on.

Security

Read-only by design.

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.

Ready when your workspace is

Put ATC inside the AI your team already uses.

Create your free account, copy the public endpoint, and turn generic AI into product-specific account intelligence.
