Description

JSON-RPC 2.0 over Streamable HTTP at https://mcp.slack.com/mcp (no SSE and no Dynamic Client Registration). MCP clients must be backed by a registered Slack app with a fixed app ID; only Slack Marketplace-published or internal apps may use MCP, and workspace admins approve and manage MCP client integrations. Users authorize through Slack OAuth (user tokens). Tools are rate-limited like the equivalent Web API methods.
