Find and Look Up Slack Users

Look up team members in your Slack workspace to find their username, status, or contact details.

In a large workspace, knowing someone's exact Slack username — the version you need to @mention them or send them a direct message — is surprisingly hard without a reliable way to search the user directory. Spelling their name slightly differently or guessing their handle wastes time and sometimes mentions the wrong person entirely.

The find_user and list_users skills let you look up workspace members by name, email, or role to get their exact Slack username, display name, status, and profile information. You can find a specific person or list all members of the workspace.

Managers adding new team members to channels, agents routing messages to the right person, and anyone onboarding to a new workspace use this to find the right Slack handle without guessing.
