## Slack AI apps: common questions

### What are the best Slack AI apps in 2026?  
The top Slack AI apps in 2026 depend on your use case. For sales and outreach, Skyp is the only MCP-native sales agent in Slack's marketplace. For customer support, Clearfeed converts Slack into a full helpdesk. For knowledge search, Eesel AI indexes your internal docs and answers questions in Slack. For engineering teams, Linear and Atlassian Rovo are both official Slack MCP launch partners. See our full ranked list at /tools/best-ai-agents-for-slack.

### Do Slack AI apps require MCP?  
No — most Slack AI apps use Slack's standard app integration (OAuth, Slash commands, Events API). MCP is a newer capability that lets Slackbot interact with apps through natural language rather than fixed commands. Apps like Skyp, Linear, Atlassian Rovo, and Amplitude support MCP; others like Clearfeed and Eesel use standard Slack app integrations. Both work well — MCP adds flexibility for natural language workflows.

### What Slack plan do I need for AI apps?  
Most AI apps work with any paid Slack plan (Pro or higher). Slack's MCP client specifically requires a paid Slack plan (Pro, Business+, or Enterprise Grid). Free Slack workspaces support standard Slack app integrations but may have restrictions on the number of installed apps. Check each app's Slack Marketplace listing for plan requirements.
