The short answer: add https://api.evyos.com/mcp as a connector in ChatGPT or Claude, sign in with your EvyOS account when asked, and approve the connection. That is all. There is nothing to install and no key to copy. It works on every EvyOS plan, including free.
The same URL is under Settings → AI assistants in the app, with a copy button.
In Claude
- Open Settings, then Connectors.
- Choose Add custom connector and paste
https://api.evyos.com/mcp. - Sign in to EvyOS when Claude sends you there, and approve the connection.
In ChatGPT
- Open Settings, then Apps & connectors, then Advanced.
- Turn on developer mode, then add a new app with
https://api.evyos.com/mcpas its URL. - Sign in to EvyOS when ChatGPT sends you there, and approve the connection.
Which ChatGPT and Claude plans allow custom connectors is set by OpenAI and Anthropic, and it changes. If you do not see the option, check their help pages for your plan.
What the assistant can do
Everything you can do in EvyOS, and only that. It works in your account, so it sees the same goals, projects, tasks, habits, skills, notes and calendar events you do, and it can create, change and complete them. Some things to try:
- "What is overdue, and what should I do first today?"
- "Add these 6 tasks to the website project, due over the next 2 weeks."
- "Tick off today's reading habit and log 30 minutes of guitar practice."
- "Write my weekly review from what I actually finished."
Your plan's limits still apply. On the free plan the assistant can have 2 active goals, 5 active projects, 20 open tasks, 5 habits and 5 skills in play, the same as you.
To work in a shared workspace, name it: "Add this to the Household workspace." Without a name, the assistant uses your personal space.
Is it safe?
The connection uses OAuth, so ChatGPT and Claude never see your EvyOS password. They get a token that only works for your account and that you can revoke at any time. The assistant is told that finishing something is not the same as deleting it. Deletions are soft, so a record removed by mistake can be restored.
Disconnecting
Go to Settings → AI assistants. Every connected app is listed there. Disconnecting one invalidates every token issued to it immediately. The conversation you had keeps whatever it already read, but it cannot read or change anything else.
Other assistants and tools
The connector is a standard MCP server, so any client that supports remote MCP servers with OAuth can use the same URL. For a tool that needs a key instead, such as a command-line agent, go to Settings → AI assistants and choose Create a key. You can scope a key to your personal space or to one workspace. Copy it when it is shown, because it is stored hashed and cannot be shown again.
