Lassare
Pause autonomous agents and route decisions or approvals to you in Slack instead of guessing on risky changes.
Overview
Lassare Ask is an MCP server for the Build phase that routes agent questions and approval requests to humans via Slack.
What is this MCP server?
- Streamable HTTP remote at mcp.lassare.com with Bearer API authentication
- Ask clarifying questions from the agent when requirements or tradeoffs are ambiguous
- Request explicit human approval before destructive or high-impact operations
- Slack as the approval surface so solo builders stay in one notification habit
- Version 1.0.1 with config sourced from lassare-hq/agent-configs on GitHub
- Remote MCP version 1.0.1
- Single streamable-http endpoint at mcp.lassare.com/mcp
- Required secret Authorization Bearer header
Community signal: 5 GitHub stars.
What problem does it solve?
Autonomous coding agents often commit to irreversible steps because they have no structured way to ask you or get a recorded yes/no.
Who is it for?
Solo builders running long agent sessions who already live in Slack and want guardrails on approvals.
Skip if: Teams that want in-IDE-only prompts with no Slack workspace or no appetite for hosted MCP auth.
What do I get? / Deliverables
After you connect Ask with a Bearer token and Slack, agents can halt, message you, and continue only once you approve or clarify.
- Registered remote MCP endpoint for ask/approve flows
- Slack messages when agents need input or sign-off
- Auditable human decisions before risky agent steps proceed
Recommended MCP Servers
Journey fit
Coding agents need a sanctioned channel to escalate while you are still implementing features and wiring workflows. Agent-tooling is the canonical shelf for MCP servers that extend how Claude Code and peers interact with humans mid-run.
How it compares
MCP human-in-the-loop bridge, not a local agent skill for writing or reviewing code.
Common Questions / FAQ
Who is Lassare Ask for?
It is for indie developers and small teams using AI coding agents who need Slack-based questions and approvals before sensitive actions.
When should I use Lassare Ask?
Use it whenever agents touch production, payments, data deletion, or unclear product decisions and you want an explicit human gate.
How do I add Lassare Ask to my agent?
Add the streamable HTTP remote https://mcp.lassare.com/mcp in your MCP client and set the Authorization header to Bearer plus your Lassare API key.
