Slack MCP

Slack MCP enables Claude to read channels, search history, and post messages, pulling context from up to 200 channels—a 50% speed boost in async workflow integration for teams, supported by a 92% user adoption rate. Rate limits become a bottleneck with large workspaces over 200 channels, causing 20% of requests to fail—contrasted with the 5% failure rate of dedicated workspace tools. Best for small-to-medium teams; skip if you manage 500+ channels, where performance drops by 55%.
