Lassare
This server gives AI coding agents like Claude Code, Cursor, and Copilot a way to ask you questions and get approvals through Slack instead of blocking at your terminal. It exposes two MCP tools: ask for clarifications and approve for risky operations. You configure it in your agent's MCP settings, and when the agent needs input or tries something dangerous like rm -rf or git push --force, you get a Slack DM or approval buttons on your phone. Built for keeping agents running while you're away from your desk. Questions expire after 15 minutes if unanswered. Works over streamable-http transport.

Lassare — Control Claude Code, Copilot, Cursor & Gemini CLI Remotely
Your AI coding agent keeps running. When it needs your input, Lassare sends the question to Slack. You answer from your phone. The agent continues.
Lassare is an MCP server that lets you respond to AI coding agent questions remotely via Slack — so you don't have to stay at your desk while your agent works.
