Summer Gate: What WebMCP-QCG Taught Me About A2A and Human Authority

Description and use

WebMCP-QCG delivers transparent, auditable quantum development decisions, preserving human authority while enabling secure agent collaboration.

Problem

Ensuring that quantum development decisions are transparent, auditable, and under human control while enabling agent-to-agent collaboration without compromising security.

Outcome

The project demonstrates a secure, auditable quantum development workflow that preserves human authority, enables agent collaboration, and provides clear evidence receipts.

Workflow

• 1. Build WebMCP-QCG with three connected surfaces (web app, DevTools panel, Companion side panel).
• 2. Share sanitized state across surfaces while keeping consent tokens and credentials isolated to the web app.
• 3. Refine UI palette, contrast, focus indicators, and accessibility controls based on real browser use.
• 4. Deploy external AI reviewers as cold judges to evaluate repository, identify fragile assumptions, and generate corrections, tests, and documentation.
• 5. Export evidence receipts after local classical simulation and human authorization.
• 6. Publish the application, repository, and evidence publicly for auditability.

Evidence

WebMCP-QCG is a browser-native preflight workbench for quantum-development decisions. It can inspect a bounded artefact, evaluate a proposed action, present a recommendation, stop for human authorization, run a supported local classical simulation, and export an evidence receipt.

Source

Raw quantum source remains inside the page. Consent tokens, credentials and private paths never cross into the extension.

I used external AI reviewers as cold judges.
