EMC/RF regulatory lookup for engineers via MCP
Features • Installation • Tools • Examples
An MCP server providing instant access to EMC emission limits, frequency allocations, restricted bands, and compliance requirements. Query FCC Part 15, CISPR, automotive, medical, and cellular standards directly from Claude Code.
Features
FCC (United States)
- Part 15.109 - Radiated emission limits (Class A/B)
- Part 15.207 - Conducted emission limits
- Part 15.209 - Radiated emission limits (intentional radiators)
- Part 15.205 - Restricted frequency bands
- Part 18 - ISM equipment limits and bands
CISPR (International)
- CISPR 11 - Industrial, scientific, medical equipment
- CISPR 32 - Multimedia equipment (replaces CISPR 22)
- CISPR 14-1 - Household appliances
- Limit comparison - FCC vs CISPR with distance correction
Cellular (3GPP)
- LTE bands - All E-UTRA bands with frequencies, duplex, bandwidths
- 5G NR bands - FR1 (sub-6 GHz) and FR2 (mmWave)
- US carrier info - AT&T, Verizon, T-Mobile band assignments
- Frequency lookup - Find which bands contain a frequency
Coming Soon
- CISPR 25 (Automotive components)
- IEC 60601-1-2 (Medical devices)
- PTCRB certification requirements

Examples
Check FCC Part 15 limits
What are the FCC Part 15 Class B radiated limits at 100 MHz?
→ Returns 43.5 dBuV/m @ 3m (quasi-peak)
Compare FCC vs CISPR
Compare FCC and CISPR Class B limits at 200 MHz
→ Shows both limits with distance correction notes
Check restricted bands
Is 121.5 MHz a restricted band?
→ Yes - aeronautical emergency frequency
Look up LTE band
What frequencies does LTE Band 7 use?
→ UL: 2500-2570 MHz, DL: 2620-2690 MHz (FDD)
Find carrier bands
What 5G bands does T-Mobile use?
→ Low: n71, Mid: n41/n77, mmWave: n260/n261
Frequency to band lookup
What cellular bands use 3500 MHz?
→ LTE Band 42, NR n77, NR n78
Check ISM bands
Is 2.45 GHz in an ISM band?
→ Yes - 2400-2500 MHz ISM band
