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
## Installation
### 1. Clone and install
```bash
git clone https://github.com/RFingAdam/mcp-emc-regulations.git
cd mcp-emc-regulations
uv pip install -e .
```
### 2. Add to Claude Code
```bash
claude mcp add emc-regulations -- uv run --directory /path/to/mcp-emc-regulations mcp-emc-regulations
```
Or manually add to `~/.claude.json`:
```json
{
"mcpServers": {
"emc-regulations": {
"command": "uv",
"args": ["run", "--directory", "/path/to/mcp-emc-regulations", "mcp-emc-regulations"]
}
}
}
```

## 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
