Find which LTE/NR bands contain a given frequency.
AI agents call frequency_to_band to retrieve information from EMC Regulations 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 regulatory reference information (band allocation data) based on a frequency query. It is a pure read operation with no side effects, data modification, or ability to execute external operations. The severity is low because misuse cannot cause harm beyond retrieving publicly available regulatory information.
From the tool's definition Tool performs a lookup/query operation: 'Find which LTE/NR bands contain a given frequency' — takes a frequency as input and returns band information. No data modification, deletion, or external action is performed.
Attacks that exploit this kind of access
Find which LTE/NR bands contain a given frequency. It is categorised as a Read tool in the EMC Regulations MCP Server MCP Server, which means it retrieves data without modifying state.
Register the EMC Regulations MCP Server MCP server in PolicyLayer and add a rule for frequency_to_band: 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 EMC Regulations MCP Server. Nothing to install.
frequency_to_band 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 frequency_to_band 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 frequency_to_band. 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.
frequency_to_band is provided by the EMC Regulations MCP Server MCP server (rfingadam/mcp-emc-regulations). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
