Connects Claude to multiple Slack workspaces in a single process and wraps every write operation in a draft plus confirm flow to prevent accidental posts. Supports xoxc cookie auth, xoxp user tokens, and xoxb bot tokens. Read tools include channel browsing, message search, thread retrieval, and user lookups. Write tools cover sending messages, threaded replies, editing your own messages, and reactions. Auto exports read channels to your vault as markdown and logs all tool calls to JSONL. Built because existing Slack MCP servers require one process per workspace and lack write confirmation. If you manage multiple Slack teams and want a safety net before posting, this gives you both in one server.
