Note: This captures a screenshot and the caller can analyze the pixel.
AI agents call get_element_colors_at_position to retrieve information from Enhanced ADB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool acquires and returns pixel color information from the device display. It is a passive data retrieval operation analogous to taking a screenshot for visual inspection. No data is modified, deleted, or executed.
From the tool's definition Tool description states 'captures a screenshot' for analysis of pixels at a position. The action is purely observational—it retrieves visual data from the device without modifying state, executing commands, or triggering side effects.

Note: This captures a screenshot and the caller can analyze the pixel. It is categorised as a Read tool in the Enhanced ADB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced ADB MCP Server MCP server in PolicyLayer and add a rule for get_element_colors_at_position: 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 Enhanced ADB MCP Server. Nothing to install.
get_element_colors_at_position 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 get_element_colors_at_position 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 get_element_colors_at_position. 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.
get_element_colors_at_position is provided by the Enhanced ADB MCP Server MCP server (rahulkr/r_adb_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
