Look up 3GPP 5G NR band information by band name (e.g., n77, n260).
AI agents call nr_band_lookup 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 read-only EMC/regulatory compliance information about 5G NR bands. It performs a lookup query of static reference data (band specifications, frequency allocations) with no capability to modify, execute, delete, or create data.
From the tool's definition Tool name 'nr_band_lookup' and description 'Look up 3GPP 5G NR band information by band name' indicate a query/lookup operation that retrieves regulatory data without modification or execution.
Attacks that exploit this kind of access
Look up 3GPP 5G NR band information by band name (e.g., n77, n260). 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 nr_band_lookup: 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.
nr_band_lookup 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 nr_band_lookup 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 nr_band_lookup. 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.
nr_band_lookup 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.
