How do I connect the Slack MCP server to Claude?
A local package is listed as @aaronsb/slack-mcp. Use the publisher's installation instructions for its complete command, arguments and authentication settings. A package name alone is not a complete Claude Desktop or Claude Code configuration.
Does the Slack MCP server work with ChatGPT?
This listing includes a local package but no hosted endpoint. ChatGPT needs a compatible remote server; check the publisher's current instructions for a hosted option. The registry entry alone does not establish whether the vendor offers one.
How do I add it to Cursor?
Use the publisher's Cursor or local MCP instructions to fill in .cursor/mcp.json. Include its complete arguments and required environment fields; the package listing above is not a ready-to-run configuration.
