Perplexity

Run security audits on Mattermost teams from Claude Desktop

The `get_all_users` tool lets your agent pull the exact list of active accounts straight into your Claude Desktop chat. It maps user IDs to bypass username spoofing attempts. You can then run `get_team_members` and `get_teams` to audit who has access to which workspaces. This setup means you don't have to jump between your terminal and the admin panel to check permissions. Your agent reads the raw database entries over the server connection, letting you spot unauthorized access patterns during active incidents.

Post and update channel alerts instantly

The `create_post` tool sends Markdown payloads directly to your active channels from the Claude Desktop interface. If you make a typo or need to add context, the `update_post` tool replaces the text and appends an edited timestamp to keep your audit trail clean. You can also use `delete_post` to completely remove a message from active UI views when sensitive data leaks. Your agent handles these mutations via simple chat commands, updating the chat history without forcing you to open the web client.

Search and extract channel history

The `search_channels` tool scans public and private rooms on your workspace to find specific discussions. Once you locate the target room, `get_channel_posts` pulls the message matrix so your agent can analyze the timeline. Use `list_team_channels` and `get_channel_details` to map out the structure of your server before pulling logs. It helps you find hidden channels where team members might be discussing active outages or deployment issues.
