📡 bakom-mcp

MCP server for BAKOM open data – broadband, mobile coverage, media and Swiss telecom statistics.

🇩🇪 Deutsche Version

Overview

bakom-mcp connects AI assistants like Claude to the Swiss Federal Office of Communications (BAKOM) open data infrastructure. It enables natural-language queries about broadband availability, 5G/4G coverage, mobile antenna locations, licensed broadcasters (RTV database), and telecommunications statistics — all without API keys.

All data is published as Open Government Data (OGD) on opendata.swiss / geo.admin.ch under CC BY 4.0 — see the Data Licence section below for attribution requirements.

Anchor demo query: "Which school buildings in district 7 do not yet have fibre optic connectivity?"

bakom_multi_standort_konnektivitaet delivers the comparison table automatically.

Scope

What this server does

✓ Read-only queries against three public BAKOM/Confederation APIs:

• api3.geo.admin.ch / wms.geo.admin.ch (broadband, mobile coverage, antennas)

• ckan.opendata.swiss (telecom statistics, dataset metadata)

• rtvdb.ofcomnet.ch (licensed radio/TV broadcasters)

✓ Returns aggregated, anonymous data — no personal data, no household-level identification.

✓ Bound to Swiss WGS84 coordinates (lat 45.8–47.9, lon 5.9–10.6) via Pydantic input validation.

✓ Egress is locked to a code-layer allow-list of the six known data-source hosts.

What this server does not

✗ Send data anywhere (read-only, no write tools).

✗ Access the local filesystem (no path-traversal surface).

✗ Use authentication tokens (none required — all sources are public OGD).

✗ Cache or persist user inputs across calls.

✗ Execute shell commands or arbitrary code (no subprocess/os.system/eval).

Features

• 📶 Broadband availability – Fixed-line coverage at 30/100/300/500/1000 Mbit/s (250×250m grid)

• 🔌 Fibre status – FTTB/FTTH availability per location

• 📍 Multi-location comparison – Connectivity check for up to 20 locations simultaneously

• 📱 Mobile coverage – 5G/4G/3G outdoor coverage (100×100m grid)

• 📡 Antenna search – Mobile and broadcast transmitters within a configurable radius

• 📺 RTV database – Search licensed radio and TV broadcasters by name, type, canton

• 🗞️ Media landscape – BAKOM media structure reports and datasets

• 📊 Telecom statistics – Fixed-line, mobile, broadband market data via opendata.swiss

• 🗂️ Broadband Atlas catalogue – All BAKOM dataset layers with direct API links

• 🔓 No authentication required – All data is Open Government Data (OGD)

Prerequisites

• Python 3.11+

• uv or pip for installation

• Internet connection (live APIs: geo.admin.ch, opendata.swiss, rtvdb.ofcomnet.ch)

Installation

# Recommended: uvx (no permanent installation required)
uvx bakom-mcp

# Or install with pip
pip install bakom-mcp

# Development install
git clone https://github.com/malkreide/bakom-mcp
cd bakom-mcp
pip install -e ".[dev]"

Quickstart

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "bakom": {
      "command": "uvx",
      "args": ["bakom-mcp"]
    }
  }
}

Config file locations:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Windows: %APPDATA%\Claude\claude_desktop_config.json

Cloud / HTTP Transport

python -m bakom_mcp.server --http
# Server running at http://localhost:8050/mcp

Configuration via environment variables (see .env.example):

Docker

A hardened container image is provided. Suitable for cloud deployments behind a reverse proxy (Caddy, Traefik, nginx).

# Build & run via compose (recommended)
docker compose up --build

# Or via docker run
docker build -t bakom-mcp:latest .
docker run --rm \
  --read-only \
  --cap-drop=ALL \
  --security-opt=no-new-privileges \
  --tmpfs /tmp:rw,size=16M \
  -p 127.0.0.1:8050:8050 \
  bakom-mcp:latest

The image runs as non-root (UID 10001), uses a read-only filesystem, drops all Linux capabilities and refuses privilege escalation. Resource limits are configured in docker-compose.yml (256 MB memory, 0.5 CPU, 64 PIDs). The default port mapping binds to 127.0.0.1 only — for public exposure, terminate TLS and CORS at a reverse proxy.

Cursor / VS Code / LibreChat

Synergies with the MCP Portfolio

bakom-mcp can be combined with other servers in the portfolio for multi-dimensional queries:

zurich-opendata-mcp  →  school building addresses
         +
    bakom-mcp         →  fibre and 5G status
         =
"Digital equity" dashboard for all school districts

Further combinations:

• srgssr-mcp + bakom-mcp → Media coverage and broadcast network

• swiss-statistics-mcp + bakom-mcp → Telecom market development

• fedlex-mcp + bakom-mcp → Regulatory context (RTVG, FMG)

    "bakom-mcp": {
      "command": "uvx",
      "args": [
