MCP.Pizza Chef: sooperset

Mention the bot in a channel or send it a direct message and it answers using whichever tools you have connected; the bundled setup ships with a small local database and a web-page fetcher. You need two Slack tokens plus a paid model account with OpenAI, Groq or Anthropic that has credit on it. Anyone who can message the bot can trigger those tools, with no confirmation step, and it runs one tool per message rather than chaining several. Unchanged since March 2025.

mcp-client-slackbot FAQ

Can I use this to answer my team's questions in Slack?
Yes. Mention it in a channel or send it a direct message and it replies in a thread.
Do I need to pay for anything?
Yes. Adding the bot to Slack is free, but it needs a paid OpenAI, Groq or Anthropic account with a balance to answer anything.
How hard is setup?
Hard. You create a Slack app from a manifest file, generate two tokens, install Python packages and keep the bot running on a machine that stays on.
Who can use the bot once it is running?
Anyone in the workspace who can message it. There is no permission list, and connected tools run immediately without asking for approval.
Does it remember our conversation?
Only the last five messages per channel, held in memory. Restarting the bot wipes all of it.
Can it do several steps in one request?
No. It runs at most one tool per message, so anything multi-step has to be broken up by hand.
Is it still maintained?
It is not archived, but nothing has changed since March 2025, so expect to fix breakages yourself.
