Manus is the purest form of vibe coding: you describe the outcome and it plans, writes, wires and ships the whole thing. Which means it's also the purest form of the risk — nobody reviews what it wrote. When a funded team ships autonomous output, a CTO and senior engineers stand between the agent and production. Manus users have no such layer. You can add one in three minutes.
The 3-minute setup
- 1. Manus → Settings → Integrations → Custom MCP Servers → Add Server.
- 2. URL:
https://mcp.verificate.ai/mcp— no authentication needed. 25 free validations, no signup. - 3. In your task prompt, add the standing rule below so Manus gates its own work.
Quality gate (mandatory):
- Before treating any code you write as finished, call
validate_ai_output on it (validate_plan for designs, before coding).
- REJECTED means stop: fix every finding, validate again.
- Report every problem the gate catches to me in your summary -
I want to know what was caught, not just that it's "done".What the gate catches in agent-built code
Verificate runs 17 deterministic reality gates — any one can veto, and no model output can talk past them — then a frontier-model review scores what survives. The gates target exactly the failure modes of autonomous generation:
- Mocked success paths — the refund handler that returns success without moving money. Vetoed outright.
- Invented APIs — verbatim from a real run: “stripe.Inventory is not a valid Stripe SDK resource.”
- Demo-only performance — “100 sequential HTTP roundtrips, ~10–20 seconds … will trigger Stripe rate limiting.” Fine in the agent's test; dead at launch.
- False completion claims — “done” without proof is itself a detected pattern.
The result: Manus keeps its speed, and every line it writes passes the review a senior team would have given it. Also works in Claude Code, Cursor, ChatGPT and any MCP client — same server, one click.
