How can I run my AI agency with Claude or ChatGPT?
By the Fullday team · Published
Connect Claude or ChatGPT to your agency platform through its connection for AI tools, often called MCP. Once connected, the assistant can read your clients, prospects, campaigns and replies, and work with you in plain words: planning your day, sorting replies, adding prospects to your pipeline and drafting outreach, reports and setups.
What can Claude or ChatGPT do once connected?
It works from your real data instead of guesses. Ask which clients need attention, which prospects replied, or what your revenue is this month, and it reads them from your platform. It can also make changes you ask for, like adding prospects or moving them through your pipeline, and it asks before doing anything that spends credits.
How do I set it up?
Setup takes a few minutes, you only do it once for each AI tool you use, and you can remove the connection from your settings at any time.
- In your agency platform, open the developer settings and create a key for your AI tool.
- In Claude, add a custom connector with the platform's address, or paste the setup command into Claude Code.
- In ChatGPT, turn on developer mode and add the platform as a connector, then sign in and allow access.
- Test it by asking for your agency overview and checking the answer against your dashboard.
- Keep your key private, and remove it from the settings if you ever share it by mistake.
What should I ask it every day?
A short routine turns the assistant into the morning meeting you'd have with a manager. Ask it to list clients who look at risk, prospects who replied and what they said, and your three most important tasks. Then ask it to draft replies and follow-ups, and you edit and send. Over a week, that routine saves hours.
