Plug Claude, ChatGPT or your coding AI into RainMakers. It can read your pipeline, work today’s
outreach queue, write emails from your own templates and log what’s done. Email goes out only from
your own Gmail, and only when you say so.

Paste it into your AI app as a custom connector, then sign in and press Allow.
In Claude (web or desktop), open Customize → Connectors, choose Add, then Add custom connector.
Name it RainMakers, paste the link above and click Continue. Leave the options marked Detected as they are.
Click Add, then Connect. Sign in to RainMakers if asked, and press Allow.
In a chat, click + → Connectors and check RainMakers is on. It works on your phone too once it’s added.
Every Claude plan; the Free plan allows one custom connector. On a Team or Enterprise plan, an Owner adds it for the organisation.
On a paid ChatGPT plan, open Plugins (older versions: Settings → Apps & Connectors) and choose + → Add custom MCP server.
Name it RainMakers and paste the link above.
Sign in to RainMakers when asked, and press Allow.
OpenAI moves these menus often; if yours look different, search ChatGPT’s help for “custom MCP server”. ChatGPT’s own Gmail connector isn’t available in every country.

Your browser opens: sign in to RainMakers and press Allow.
Let it send from your Gmail. In Claude, also connect Gmail (Customize → Connectors).
Then your AI can send outreach straight from your own Gmail, without you opening anything. It shows you
each email first unless you’ve allowed it to send.
After a RainMakers update, disconnect and reconnect RainMakers in your AI app so it picks up
anything new. Your AI app remembers the list of things RainMakers can do from when you connected.
Safe by design. Needs RainMakers Pro, and you approve every connection. It can’t see your
password or billing, or download templates. It never sends email itself, asks before deleting anything, and
works within daily limits. See what it’s done, or disconnect it, in Settings → Your AI.
Things To Ask
“Find 100 local business leads with poor websites and mobile numbers.”
“What’s due today in RainMakers? Send the emails from my Gmail, then log them.”
“Find my leads with an email that aren’t on a cadence, and enrol them in Value First Flow.”
“Show me everything on my best lead, and suggest what I should do next.”
