Get cellular cell info: CID, LAC, signal level, ARFCN.
AI agents call get_telephony_cell_info to retrieve information from Android MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves telephony metadata (cell tower identifiers and signal strength) from the device without modifying state or triggering external operations. It is a Read operation. Severity is medium rather than low because cellular location data (CID, LAC) can be sensitive for privacy and device fingerprinting purposes, making misuse moderately concerning.
From the tool's definition Tool name contains 'get_' prefix and description specifies retrieval of 'cellular cell info: CID, LAC, signal level, ARFCN' with no indication of modification, deletion, or execution capabilities.

Get cellular cell info: CID, LAC, signal level, ARFCN. It is categorised as a Read tool in the Android MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Android MCP Server MCP server in PolicyLayer and add a rule for get_telephony_cell_info: 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 Android MCP Server. Nothing to install.
get_telephony_cell_info 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_telephony_cell_info 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_telephony_cell_info. 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_telephony_cell_info is provided by the Android MCP Server MCP server (wujie272/android-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
