README

slack-mcp

Multi-workspace Slack MCP server with draft+confirm safety, vault auto-export, and triple-mode auth.

One process, N workspaces, every write goes through draft → confirm. Built because the existing Slack MCP servers are single-workspace per instance and the Anthropic reference impl was deprecated.

Why use this over the alternatives

	This	Anthropic connector	korotovsky/slack-mcp-server
Multi-workspace per server	Yes	No	No
Draft + confirm on writes	Yes	No	No
Vault auto-export of reads	Yes	No	No
Prompt-injection scrubber	Yes	No	No
Audit log	Yes	No	No
xoxc / xoxp / xoxb auth	Yes	n/a	Yes
Status	Active	Active (limited)	Active

Install

Open Claude Code, paste:

/plugin marketplace add adelaidasofia/slack-mcp
/plugin install slack-mcp@slack-mcp

Then fill in tokens in .env (see SETUP.md for cookie extraction walkthrough).

Legacy install

git clone https://github.com/adelaidasofia/slack-mcp.git ~/.claude/slack-mcp
cd ~/.claude/slack-mcp
pip3 install --break-system-packages -r requirements.txt
cp .env.example .env
# fill in tokens — see SETUP.md for cookie extraction walkthrough

{
  "mcpServers": {
    "slack": {
      "command": "python3",
      "args": ["-m", "slack_mcp.server"],
      "cwd": "/Users/YOU/.claude/slack-mcp"
    }
  }
}

Restart Claude Code, then run claude mcp list to verify slack shows up.

Tools (v0.1.1)

Meta: list_workspaces, healthcheck

Read: list_channels, search_channels, read_channel, read_thread, list_users, search_users, get_user_profile, search_messages

Write (draft+confirm): send_message → confirm_send, send_reply_quote → confirm_send, update_own_message → confirm_send, cancel_draft

Write (low-consequence, immediate): add_reaction, mark_read, delete_own_message

Auth modes

Mode	Token shape	Capability	When to use
`xoxc`	`xoxc-...` + `xoxd-...` cookie	Full (search, internal APIs)	Default. Best for personal use across multiple workspaces.
`xoxp`	`xoxp-...`	Permanent, OAuth, search restricted on free plans	If you don't want occasional cookie re-extraction.
`xoxb`	`xoxb-...`	Bot-only, no search, invited channels only	Rare. Use only when you want bot semantics.

Cookie extraction takes ~3 minutes per workspace. See SETUP.md.

Vault auto-export

Every read_channel call mirrors the channel to <vault>/🤖 AI Chats/Slack/<workspace>/<channel>.md. Idempotent (same channel + day overwrites cleanly). Disable via
