Human-in-the-Loop MCP server that enables AI assistants to request information from humans via Slack
If you want an AI assistant working directly with AskOnSlackMCP, the askonslackmcp mcp server is the bridge. Human-in-the-Loop MCP server that enables AI assistants to request information from humans via Slack.
A Model Context Protocol (MCP) server that enables AI assistants to request information from humans via Slack. This server acts as a bridge between AI systems and human experts, allowing AI to ask questions and receive responses through Slack when it needs human knowledge or clarification.
Once connected, the assistant can call these 3 tools directly:
ask_on_slack — The ask_on_slack tool exposed by this serverScripts — The Scripts tool exposed by this serverTesting — The project uses Vitest for testing. Tests are located in the tests/ directoryThe server is distributed via npm as Run, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
connections:write scope - Install the app to your workspace 2. Bot Token Scopes - chat:write - Send messages - channels:read - Access channel information - users:read - Access user information 3. Socket Mode - Enable Socket ModeCommunication servers earn their keep on volume — summarising channels and threads that would otherwise cost you an hour of scrollback. AskOnSlackMCP sits in that group, and the shape of its toolset — ask_on_slack, Scripts, Testing — tells you what it is really for. Worth comparing against the other communication servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
