Handles the read-heavy Slack operations you actually need: searching channels, pulling message history, and creating new channels when necessary. The categorization feature uses AI to sort through message content, which is genuinely useful if you're building internal digests or trying to surface what matters from high-traffic channels. It's read-only except for channel creation, which is the right default. The integration patterns are smart, like piping Slack discussions into newsletter generation or cross-referencing with meeting transcripts. Rate limits are reasonable at 50 requests per minute. Just remember that Slack messages are often sensitive, so the security notes about not logging content and minimizing scopes aren't just checkbox compliance.
