EMC and RF regulatory lookup: emission limits, immunity levels, restricted bands, and certification matrices. Drive it from your IDE, terminal, or AI agent the moment a compliance question shows up.
Quick start · Tools · Workflows · Documentation
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 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.

"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.

Scored across 45 tools
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.
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.
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.
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.
