Lassare MCP server

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.

Supported Agents

Tested & Documented

• Claude Code — MCP config, slash commands, hooks
• GitHub Copilot (VS Code) NEW — MCP config, prompt files, hooks
• Cursor — MCP config, slash commands, hooks
• Gemini CLI — MCP config, slash commands, hooks

Other MCP Clients

Lassare works with any MCP-compatible agent (Windsurf, Continue, Aider, and more). Use the generic config as a starting point.

Using a different agent? Let us know what works or what you'd like us to support next.

Quick Start

1. Sign up at portal.lassare.com and connect your Slack workspace
2. Get your API key from Agent Setup
3. Choose your agent from the folders above
4. Follow the README in that folder

Setup is manual — you copy config files into your project. This keeps everything transparent and customizable with no hidden dependencies.

How It Works

┌────────────────┐     ┌─────────────┐     ┌─────────────┐
│  Your Agent    │────▶│   Lassare   │────▶│ Your Slack  │
│ (ask / approve)│◀────│   (MCP)     │◀────│ (DM/mobile) │
└────────────────┘     └─────────────┘     └─────────────┘
  agent continues       relays answer        you respond

Two tools:

1. ask — Agent needs clarification → you get a Slack DM → reply with your answer
2. approve — Agent needs permission for a risky action → you get Approve/Deny buttons in Slack

Hooks (included for supported agents):

• Auto-approve mode keeps the agent moving between questions
• Lassare hooks intercept dangerous commands (rm -rf, git push --force, sudo, etc.) and route them to Slack — so you stay in control from anywhere
• The list of dangerous commands is customizable in permission-approve.sh
• A stop hook asks "Anything else?" before the agent stops

Questions and approvals expire after 15 minutes if not answered.

Common Questions

How do I control Claude Code remotely? Add Lassare as an MCP server in your .mcp.json. When Claude Code needs input, it calls the ask tool — the question arrives on Slack, you respond from your phone, Claude Code continues.

Can I answer Cursor questions from my phone? Yes. Configure Lassare in Cursor's MCP settings. When the agent hits a decision point, you get a Slack notification and reply from anywhere.

Does GitHub Copilot in VS Code work with Lassare? Yes. VS Code 1.109+ supports MCP servers and agent hooks. Add Lassare to .vscode/mcp.json and enable hooks for remote approval of dangerous commands.

Does Gemini CLI work with Lassare? Yes. Gemini CLI supports MCP servers. Add Lassare to your settings and agent questions arrive via Slack.

Can I use my AI coding agent while AFK? That's exactly what Lassare is for. Your agent keeps running wherever it's running — you just answer questions remotely via Slack when it needs your input.

Is my code sent to Lassare? No. Lassare only sees the questions your agent sends. Your code stays on your machine.

Modes

• Inline mode (default): Questions asked directly in the conversation — for when you're at your desk
• Slack mode: Questions go to your Slack DM — respond from your phone while AFK

Toggle with /lassare-slack or /lassare-inline commands.
