A workflow overview, not a claim that agents automatically implement or accept every comment.

Share a stable review link

Select repositories through the GitHub App and discover reviewable files. Reviewers open the prototype and leave feedback in context.

Give the next step its context

Export Markdown or retrieve comments through MCP. Static review restricts scripts and form execution; it does not host arbitrary application backends.

Six steps from repository to revision

  1. Install the ProtoLens GitHub App on selected repositories.
  2. Open the dashboard and choose a repository.
  3. Discover static prototypes such as index.html, SVG and PNG files.
  4. Open or copy a stable review link.
  5. Reviewers comment on selected text or regions.
  6. Export Markdown or read feedback through MCP, then revise and review.

For independent builders, small product teams, internal tools and agent workflows that need quick human review.

Let agents continue with the feedback

The MCP server can list prototype files, create review links, read comments and export Markdown. Add the server URL to a client that supports remote MCP and follow the dashboard and documentation for authentication. Some clients support short-lived bearer tokens generated in the dashboard.

GitHub access and review data boundaries

Your GitHub App installation controls repository access. Prototypes are fetched by repo, ref and path, without cloning repositories or executing arbitrary builds. Comments are Markdown-oriented review data linked to GitHub-backed prototypes; this does not mean all comments are stored in your repository. HTML rendering is sandboxed, JavaScript and form submission are constrained, and files exceeding current safety or resource limits may be refused.
