このサーバーについて
Slack runs its own MCP server at mcp.slack.com, which clients reach over Streamable HTTP; SSE connections are not accepted. Every client has to be backed by a registered Slack app that signs users in with confidential OAuth, and each tool works only when the matching user-token scopes have been granted. Workspace admins approve MCP clients and can review their activity in audit logs. The tools search messages, files, people and channels, read channel history and threads, send, schedule and draft messages, add reactions, work with canvases and lists, and upload files. Rate limits follow the Slack Web API tiers. Slack names Claude, Claude Code, Cursor and Perplexity as partner clients.
