Check if a frequency falls within FCC Part 15.205 restricted bands.
AI agents call fcc_restricted_bands 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 is a reference data query tool that retrieves FCC regulatory information. It has no capability to modify regulations, execute operations, delete data, or commit financial transactions. The worst-case misuse would be an AI agent receiving incorrect frequency band information for engineering reference, which poses minimal risk. Classified as Read with low severity.
From the tool's definition Tool performs a lookup/query to "Check if a frequency falls within FCC Part 15.205 restricted bands" - this is a read-only compliance lookup with no side effects, modifications, or operational impact.
