FAQ from slack-mcp-server

What tokens are required?

SLACK_BOT_TOKEN (bot user OAuth token) is required for most operations. SLACK_USER_TOKEN (user OAuth token) is needed for features like message search.

What does `SLACK_SAFE_SEARCH` do?

When set to true, it automatically excludes private channels, DMs, and group DMs from search results. This is enforced server-side and cannot be overridden by clients.

What transports are supported?

Stdio transport (default for local integration) and Streamable HTTP transport (specify with -port 3000 for web applications). The HTTP endpoint is http://localhost:3000/mcp.
