Prerequisites

You need to register an OAuth app with Linear once. Create an OAuth application in your Linear workspace settings. Set the callback URL to authsome’s, and copy the client ID and secret.

The redirect URI must be:

http://127.0.0.1:7998/auth/callback/oauth

This is the only callback URL authsome’s PKCE flow listens on.

Dashboard: https://linear.app/settings/api/applications/new.

Log in

authsome login linear

The first time, authsome opens a local form at http://127.0.0.1:7998 to collect your client_id and client_secret. They are encrypted in your vault and reused on every subsequent login. A second browser window then opens to https://linear.app/oauth/authorize for the authorization step.

Verify:

authsome get linear --field status
# → connected

Custom scopes

The bundled definition requests read, write. Override at login time:

authsome login linear --scopes "<comma-separated>"

The granted scopes are stored on the connection and visible in authsome get linear.

Multiple accounts

Pass --connection <name> on login and on every read command to keep two or more accounts on the same provider side by side. See Multiple connections per provider for the full pattern.

authsome login linear --connection personal
authsome login linear --connection work

Use the token

Run the agent under the proxy (recommended).

Proxy (recommended)

authsome run -- python my_agent.py

eval "$(authsome export linear --format env)"

Under the proxy, authsome sets LINEAR_ACCESS_TOKEN=authsome-proxy-managed in the child’s environment and injects the real token into outbound requests to regex:.*\.linear\.app. The child process never sees the actual value. Refresh tokens are never exported.

Override the bundled definition

authsome inspect linear > ~/.authsome/providers/linear.json
# edit scopes, base_url, or anything else
authsome list   # source now shows "custom" for linear

User-registered files always win over bundled definitions.

What’s next

Inject the access token into outbound requests without exposing it.
