A coaching MCP server: run your client roster from Claude
Trainzilla has a remote MCP server, so Claude can read your real clients and act on them: check-ins, habits, plans, sessions and gym data. Every change is shown to you as a preview first and only saved when you confirm.
Start free, no cardAvailable to every Trainzilla coach account.
How it works
- Step 1
Add the connector
In Claude, open Settings → Customize → Connectors, add a custom connector and enter https://api.tzilla.live/mcp. That URL is the only setup.
- Step 2
Sign in to Trainzilla
Claude sends you to Trainzilla to sign in and approve access (OAuth 2.1 with PKCE). Claude never sees your password and you can revoke access any time.
- Step 3
Ask about real clients
"Who is below 70% habit compliance this fortnight and hasn’t checked in this week?" Claude answers from your live account, not a demo.
What’s included
- Read clients, profiles, habits, check-ins and photo answers, sessions, subscriptions and billing
- Draft workout and diet plans and templates from the real Trainzilla exercise and food catalog
- Schedule, reschedule and cancel sessions; create check-ins and habits; message a client
- Gym tools: classes and rosters, attendance, coaches, locations, prospects and announcements
- Calculators for TDEE, macros and one-rep max
- Every write returns a preview and needs a second, explicit confirmation
- Access is scoped to your own coach account and your role in a gym
Questions
Which AI assistants work with it?
Claude on claude.ai and in the Claude desktop app, using a custom connector. Any other MCP client that supports remote servers with OAuth sign-in can connect to the same URL.
Can Claude change a client’s plan without me knowing?
No. Every write first returns a preview of exactly what would be created or changed. Nothing is saved until you confirm in the chat.
Does it cost extra?
No. The MCP server is part of your Trainzilla account. You use your own Claude plan.
Can it take payments or delete data?
Taking payments and refunds are not exposed. Deleting plans or templates, like every other write, needs your explicit confirmation.
