| Upload File | Upload a file (image, GIF, video, PDF) to a Slack channel, DM or thread |
| Get Channel Info | Get information about a Slack channel |
| Search Channels | Search for Slack channels that the bot has access to. Returns public and private channels. Use slack-search-users to find users for direct messages instead. |
| Search Users | Search for Slack users by name, display name, or email. Use this to find a user's Slack ID, which can then be used as a channelId to send them a direct message via slack-send-message. For an exact email match, prefer slack-lookup-user-by-email. |

Access and security
- You grant access on Slack's own consent screen, and Malleable stores the resulting token, never your password.
- Each workflow chooses whose Slack account the actions above use: its owner's for every run, or that of whoever starts the run, which keeps each person to what their own account can reach.
- You can revoke access at any time in Slack's settings.
Malleable is SOC 2 Type II audited and doesn't train AI models on your data. More in Security & data handling and our Trust Center.
