MCP App view

MCP hosts that support MCP Apps (the MCP UI extension) can show JustClaw-It results as an interactive view instead of raw JSON. Hosts that don't support it get exactly the same JSON text, so nothing changes for them.

What it shows

• Search results (search_components, find_similar): a card per component with repository, path, language, licence, lines of code, scores, similarity, tags, the attribution line and the GitHub permalink, plus a filter box that narrows the list by name, repo, language or tag.
• One component (get_component): the same card with dependencies and the component id, the source code, and a Copy source button.
• Errors from the tool (for example running out of credits) as a readable message.

How it works

• The tools declare the view in their metadata (_meta.ui.resourceUri = ui://justclaw-it/components.html). The view is a resource with MIME type text/html;profile=mcp-app.
• The host renders it in a sandboxed frame. It only displays what the tool already returned: it never calls tools itself, so it can never spend a credit.
• Reading the view resource is free.
• The view loads the MCP Apps helper library from unpkg.com, the only external domain its content-security metadata declares.

The view picks up the host's light or dark theme and style variables when the host provides them.
