List all 5G NR bands, optionally filtered by frequency range (FR1 sub-6GHz, FR2 mmWave).
AI agents call nr_bands_list 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 information about 5G NR (New Radio) frequency bands and their allocations. It performs a read-only query operation without side effects, modification of data, or execution of external code. The 'optionally filtered' parameter is a filter on the returned data, not a destructive or executable action.
From the tool's definition Tool name 'nr_bands_list' and description 'List all 5G NR bands, optionally filtered by frequency range' indicate a retrieval/query operation with no modification, deletion, or execution of commands.
Attacks that exploit this kind of access
List all 5G NR bands, optionally filtered by frequency range (FR1 sub-6GHz, FR2 mmWave). 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_bands_list: 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_bands_list 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_bands_list 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_bands_list. 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_bands_list 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.
