Actium
Setup guide

Connect Claude and ChatGPT

Point your assistant at Actium once. After that, ask it what you are behind on — or tell it to add something — and your plan changes with it.

SERVER ADDRESS
https://theactium.com/api/v1/mcp

The same address for both assistants. You will need an Actium account — the assistant sends you to Actium to sign in, and it only ever sees what that account can see.

The sign-in page is always on actium-prod.auth.us-east-1.amazoncognito.com. Nothing else ever asks for your Actium password.

Claude

Let Claude read and change your Actium tasks while you're talking to it.

WHAT TO ENTER
Server address
https://theactium.com/api/v1/mcp
OAuth client ID
fq57det1jc1e1tcsd5gddu89l
HOW TO CONNECT
  1. 1In Claude, open Customize → Connectors → Add custom connector.
  2. 2Name it Actium. Server URL: https://theactium.com/api/v1/mcp
  3. 3Authentication: Sign in now. OAuth client: Use your own OAuth client.
  4. 4OAuth client ID: fq57det1jc1e1tcsd5gddu89l. Leave the secret blank and add no request headers.
  5. 5Press Add, then sign in with your Actium username and password on actium-prod.auth.us-east-1.amazoncognito.com.
WHAT YOU CAN DO
  • Ask what you're behind on across every project
  • Ask what's actually scheduled in the days ahead
  • Create, edit, reschedule, assign and finish tasks
  • Give it a read-only key and it can change nothing

It only reaches your projects, and it deletes nothing.

Claude reaches Actium from Anthropic's servers, so this works on web, desktop and mobile. Using Claude Code instead? Create a key under Settings → API keys in the Actium app and run the command below.

ChatGPT

Let ChatGPT read and change your Actium tasks while you're talking to it.

WHAT TO ENTER
Server address
https://theactium.com/api/v1/mcp
OAuth client ID
5ujr2fv1k4jtajv8dloemg4f2
HOW TO CONNECT
  1. 1In ChatGPT (paid plan), open Settings → Security and login → turn on Developer mode.
  2. 2Add a server: name Actium, public endpoint https://theactium.com/api/v1/mcp, authentication OAuth.
  3. 3OAuth client ID: 5ujr2fv1k4jtajv8dloemg4f2. There is no secret.
  4. 4Then sign in with your Actium username and password on actium-prod.auth.us-east-1.amazoncognito.com.
WHAT YOU CAN DO
  • Ask what's on your plate today, this week or overdue
  • Ask what's actually scheduled in the days ahead
  • Create, edit, reschedule, assign and finish tasks
  • Log a habit check-in, or read a whole project back

It only reaches your projects, and it deletes nothing.

ChatGPT asks before any change is written. If signing in fails with a redirect error, the callback URL ChatGPT shows has to be registered — send it to us from the Contact page.

Claude Code

One command, if you live in the terminal.

Claude Code authenticates with a key instead of a browser sign-in. Create one in the Actium app under Settings → API keys — you see the key once — then run:

claude mcp add --transport http actium https://theactium.com/api/v1/mcp --header "Authorization: Bearer <your key>"

The app shows this same command with your key already in it. Revoke a key there any time and the connection stops working immediately.

Permissions

You choose how much it can touch.

Read-only

The assistant can list your tasks, projects and habits and answer questions about them. It cannot create, change or complete anything.

Read and write

Everything above, plus creating, editing, rescheduling, assigning and finishing tasks and logging habit check-ins. Deleting is never included.

ChatGPT confirms writes. It shows you the change and asks before anything is written to your plan. In Claude, an API key made read-only can change nothing at all, whatever it is asked to do.
If it does not connect

Tell us what the assistant said and we will look at it — support@actium.app. What Actium keeps, and what it never does, is written out on the privacy page.

Your plan, from whichever assistant you happen to be talking to.
