## What is mcp-emc-regulations?
`mcp-emc-regulations` is an MCP server that answers concrete EMC and RF
compliance questions: emission limits, immunity test levels, frequency
allocations, restricted bands, certification requirements: directly
from cited standards. No PDFs, no copy-paste from a regulatory site.
It implements lookups against curated datasets sourced from **FCC Part
15/18/95**, **CISPR 11/12/14-1/22/25/32**, **IEC 61000-4-x**,
**ISO 11452 / 7637 / 16750**, **3GPP TS 36.101 / 38.101**, **ISED RSS-Gen**,
and EU harmonised standards. Live FCC text is fetched on demand from the
official **eCFR API**.
**What it does well:**
- 🤖 **AI-native via MCP.** First-class [Model Context Protocol](https://modelcontextprotocol.io)
server with **45 tools** across FCC, CISPR, automotive, medical,
cellular, wireless protocols, and certification advisory.
- 🐍 **Multiple surfaces.** Use it from any MCP client (Claude Desktop,
Claude Code, Codex), or call the Python package directly.
- ⚡ **Cited and dated.** Every dataset carries `source`, `version`, and
`last_updated`. The `data_sources` tool reports current versions; live
eCFR queries are tagged with the eCFR snapshot date.
- ✅ **Composable.** Compare FCC vs CISPR at a frequency with distance
correction. Generate full test plans (`test_plan_generator`,
`immunity_test_plan`) across regions and standards in one call.
- 🔒 **MIT licensed.** Drop-in for compliance review workflows.

## Quick start
### Install
> Pre-alpha: not yet on PyPI. Install from source:
>
> ```bash
> git clone https://github.com/RFingAdam/mcp-emc-regulations.git
> cd mcp-emc-regulations
> uv pip install -e .
> ```
### Two surfaces, same answer
<table>
<tr>
<td valign="top" width="50%">
**Python**
```python
from mcp_emc_regulations.tools import fcc
# FCC Part 15.109 Class B radiated limit at 100 MHz
result = fcc.fcc_part15_limit(
section="15.109",
frequency_mhz=100,
classification="B",
)
print(result)
```
</td>
<td valign="top" width="50%">
**CLI** (via `uv run`)
```bash
uv run --directory /path/to/mcp-emc-regulations \
mcp-emc-regulations
# JSON-RPC over stdio: drive it from any MCP client
```
</td>
</tr>
<tr>
<td colspan="2" valign="top">
**MCP (Claude Desktop, Claude Code, Codex CLI, any MCP client)**
Add to your `claude_desktop_config.json`:
```json
{
"mcpServers": {
"emc-regulations": {
"command": "uv",
"args": ["run", "--directory", "/path/to/mcp-emc-regulations", "mcp-emc-regulations"]
}
}
}
```
Then ask your assistant in plain English:
> *"What's the FCC Part 15 Class B radiated limit at 100 MHz, and how does it
> compare to CISPR 32 Class B at the same frequency?"*
The agent calls `fcc_part15_limit` and `emc_compare_limits` and reports
both with distance corrections.

## Data currency
- Curated datasets in `src/mcp_emc_regulations/data/` carry `metadata` fields
with `source`, `version`, and `last_updated`. Use the `data_sources` tool to
see versions at runtime.
- `ecfr_query` pulls live CFR text from the eCFR API on each call.
- For compliance work, verify against the official standard before sign-off.
External sources can be configured in `sources.json`; use `sources.local.json`
for private overrides. Run:
```bash
uv run python scripts/update_sources.py
```
to refresh `data_sources/manifest.json`.

TDQS
B3.4/5.0
Scored across 45 tools
Disambiguation4/5
Most tools have distinct purposes, e.g., separate tools for different CISPR parts and FCC parts. However, some overlap exists between advisor tools (certification_matrix, product_certification_advisor, market_requirements) and test planners (test_plan_generator, immunity_test_plan), though descriptions clarify roles.
Naming Consistency4/5
Tool names predominantly follow a descriptive noun_verb pattern (e.g., cispr12_limit, fcc_part15_limit, lte_band_lookup). Some abbreviations are used consistently, but a few names like 'frequency_to_band' break the pattern. Overall, naming is clear and mostly consistent.
Tool Count2/5
45 tools is excessive for typical server usage, risking agent confusion and selection overhead. While the domain is broad, many tools could be consolidated (e.g., merging related limit queries or test planners). This high count likely degrades coherence.
Completeness5/5
The tool set thoroughly covers EMC regulations: limits from major standards (CISPR, FCC, ISED), test methods (automotive, medical, general), certification roadmaps, market-specific requirements, and cross-references. No obvious gaps for the stated domain.
