Implementation Reference

• src/mcp_emc_regulations/tools/fcc.py:387-423 (handler)

  Handler function _cbrs_rules() that executes the 'fcc_cbrs_rules' tool logic. Retrieves Part 96 CBRS data from FCC_ADDITIONAL JSON and formats it with frequency, bandwidth, LTE/NR bands, access tiers (PAL/GAA), device categories, and SAS info.

      cbrs = FCC_ADDITIONAL.get("parts", {}).get("part_96", {})

• src/mcp_emc_regulations/tools/fcc.py:126-131 (registration)

  Tool registration in the list_tools() method of FCCTools class. Defines the 'fcc_cbrs_rules' tool with name, description, and empty input schema.

      Tool(
          name="fcc_cbrs_rules",
          description="Get FCC Part 96 CBRS (Citizens Broadband Radio Service) rules for 3.5 GHz shared spectrum.",
          inputSchema={"type": "object", "properties": {}},
      ),
  ]

• src/mcp_emc_regulations/tools/fcc.py:129-129 (schema)

  Input schema for 'fcc_cbrs_rules' — an empty object (no parameters required).

  inputSchema={"type": "object", "properties": {}},

• src/mcp_emc_regulations/tools/fcc.py:148-149 (registration)

  Dispatch in call_tool() method routing the 'fcc_cbrs_rules' tool name to the _cbrs_rules() handler.

  elif name == "fcc_cbrs_rules":
      return self._cbrs_rules()

• src/mcp_emc_regulations/tools/fcc.py:15-18 (helper)

  Loading of the fcc_additional_parts.json data file which contains the Part 96 CBRS rules data used by _cbrs_rules().

  PART15_LIMITS = load_json("part15_limits.json")
  PART18_LIMITS = load_json("part18_limits.json")
  RESTRICTED_BANDS = load_json("restricted_bands.json")
  FCC_ADDITIONAL = load_json("fcc_additional_parts.json")
