What it asks, the evidence, the command that verifies it and the fix on 19 platforms. Source: https://agentreadychecklist.com/checklist/ar-act-05 Site: Agent Ready Checklist Last reviewed: 2026-11-05 Agent endpoints: https://agentreadychecklist.com/llms.txt (index), https://agentreadychecklist.com/openapi.json (API), https://agentreadychecklist.com/mcp (MCP server), https://agentreadychecklist.com/ask (search) Access: https://agentreadychecklist.com/auth.md (no key). Pricing: https://agentreadychecklist.com/pricing.md (free). # AR-ACT-05: MCP Apps view AR-ACT-05 is a MAY on the act layer: Products with a UI may ship an MCP Apps view (ui:// resource) so the agent can hand a working surface back to the user. It applies to products with a UI and an MCP server. 19 of 19 platforms have a recipe below, 15 of them workarounds. ## The requirement Identifier AR-ACT-05 Level MAY Layer Act Applies to products with a UI and an MCP server Checked by Ora, matched on this site Ora check [mcp-app-registry](#ora) The statement Products with a UI may ship an MCP Apps view (ui:// resource) so the agent can hand a working surface back to the user. ## Why - The spec lists AR-ACT-05 as MAY with no measured evidence.primary source: [github.com/agentready-org/standard/blob/main/spec/spec.md](https://github.com/agentready-org/standard/blob/main/spec/spec.md), read 2026-11-04 - Ora published an experiment on 2026-09-30 in which a WebMCP tool returns an MCP App to the host.vendor claim, 2026-09-30: [ora.ai/blog/when-a-webmcp-tool-returns-an-mcp-app](https://ora.ai/blog/when-a-webmcp-tool-returns-an-mcp-app?utm_source=agentreadychecklist.com&utm_medium=referral&utm_campaign=requirement), read 2026-11-04 ## How to verify No Verify Kit check covers this row, so the test is manual. ### The one-line version Call resources/list on the MCP server and look for a uri starting with ui://. ## Verify with Ora One check in Ora's catalogue (contract 1.38.0, read 2026-11-05) read this row. Each entry says what the check looks at and why this page lists it. - `mcp-app-registry` MCP Apps support Looks for MCP Apps, interactive views the server exposes. Usability, 4 points, recommended; catalogue applicability mcp-app. Listed because: same name, `mcp apps`. ### Run just these checks ```bash curl -s -X POST https://ora.ai/api/scan/checks -H 'content-type: application/json' -d '{"url":"https://example.com","checkIds":["mcp-app-registry"]}' ``` This calls the endpoint Ora documents for re-verifying a fix. It sends no cache, returns a result for each id and no total score, and spends one scan from the daily budget. Replace the URL with yours. [How to re-verify one fix](https://agentreadychecklist.com/guides/re-verify-one-fix-with-ora/). ### Or audit the whole site ```bash npx ax@0.10 audit https://example.com --min-score 70 ``` ### Related checks These checks read something near the row but ask for more than the row does. A site that meets the row can score nothing or lose points on them, so they are not counted as tests of the row and are left out of the command above. - `mcp-view-domain` MCP App view reachable Tests that the view an MCP App points at loads publicly and serves HTML without an auth wall. The row asks that a view exists, not that it is public, so a site that meets the row can lose points here. Usability, 4 points, recommended; catalogue applicability mcp-app. - `mcp-view-csp` MCP App view CSP Tests that the Content Security Policy declared for the view names specific origins or is left out. The row asks for a view, not for a policy, so a site that meets the row can lose points here. Usability, 4 points, recommended; catalogue applicability mcp-app. - `mcp-apps-ui-quality` MCP Apps UI quality Tests the MIME type, HTML validity, dark mode support and the absence of hardcoded secrets in the view. A bonus check that reads the quality of a view, which the row does not ask for. Usability, 4 points, bonus, recommended; catalogue applicability mcp-app. Exit code 1 means the score is below the number you passed, so the same line gates a deploy: [the CI recipe](https://agentreadychecklist.com/guides/gate-deploys-on-agent-readiness-in-ci/).
