Verify HD/FHD resolution support. Checks: 1. Device ui-resolution (720p/1080p/2160p) via GET :8060/query/device-info 2. Manifest ui_resolutions setting (hd, fhd) 3. images/hd/ and images/fhd/ resource directories Reports any mismatches or missing resources. Ref: developer.roku.com/docs/developer-...
AI agents call roku_check_resolution to retrieve information from Roku MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool purely retrieves and inspects device configuration data to verify resolution support compliance. It queries device state via GET requests and checks resource availability, producing diagnostic reports without side effects. No data is modified, deleted, or executed—it is strictly informational for certification verification purposes.
From the tool's definition Tool performs verification and checking operations: 'Verify', 'Checks', 'Reports' with GET requests to query device information.

Verify HD/FHD resolution support. Checks: 1. Device ui-resolution (720p/1080p/2160p) via GET :8060/query/device-info 2. Manifest ui_resolutions setting (hd, fhd) 3. images/hd/ and images/fhd/ resource directories Reports any mismatches or missing resources. Ref: developer.roku.com/docs/developer-program/core-concepts/resolution.md. It is categorised as a Read tool in the Roku MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Roku MCP Server MCP server in PolicyLayer and add a rule for roku_check_resolution: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Roku MCP Server. Nothing to install.
roku_check_resolution is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the roku_check_resolution rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for roku_check_resolution. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
roku_check_resolution is provided by the Roku MCP Server MCP server (maskelog/roku-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
