An MCP server that connects AI models to Lobbywatch.ch, the largest lobby database of the Swiss Federal Parliament β conflicts of interest, lobby groups, access badges, and transparency scores.
Part of the Swiss Public Data MCP Portfolio β connecting AI models to Swiss public data sources.
"Welche Mitglieder der WBK-N haben Interessenbindungen zu Bildungsverlagen oder privaten BildungstrΓ€gern, und wie ist ihre Transparenz-Bewertung?"
Which members of the National Council's Education Commission have declared conflicts of interest with educational publishers or private education providers, and how does their compensation transparency score compare?
β More use cases by audience β
Lobbywatch.ch maintains the largest public database on Swiss federal parliamentarians and their connections to lobby organisations: 245 parliamentarians, ~7'800 interessenbindungen (declared mandates), 139 lobby groups, 368 access-badge holders, updated weekly, licensed CC BY-SA 4.0.
lobbywatch-mcp exposes this data to Large Language Models via the Model Context Protocol. It is designed to be used alongside parlament-mcp (the official Swiss Parliament's Curia Vista data): the pair makes it possible to ask what a parliamentarian did officially and who they are connected to β in a single conversation.
dataIF REST API is used only where it returns reliable data (lobby groups, search).stdio for Claude Desktop, streamable-http / sse for cloud deployments. βββββββββββββββββββββββββββββββ

Outbound HTTP runs through a single httpx.AsyncClient with follow_redirects=False, an SSRF guard that blocks RFC1918 / link-local / metadata IPs, and an httpx event hook that re-resolves on every request. The dump path is the primary source of truth for parliamentarian queries; dataIF is only used for lobby group lookups and the search endpoint.
From PyPI (after first release):
pip install lobbywatch-mcp
From source:
git clone https://github.com/malkreide/lobbywatch-mcp.git
cd lobbywatch-mcp
pip install -e ".[dev]"
lobbywatch-mcp
This starts the server in stdio mode. For HTTP:
LOBBYWATCH_MCP_TRANSPORT=http LOBBYWATCH_MCP_PORT=8000 lobbywatch-mcp
A hardened multi-stage Dockerfile ships with the repo (non-root,
read-only-rootfs compatible). See docs/deployment.md
and deploy/docker-compose.example.yml
for resource limits, sticky-LB guidance and egress hardening.
docker build -t lobbywatch-mcp:0.2.0 .
docker run --rm -p 127.0.0.1:8000:8000 lobbywatch-mcp:0.2.0
Add to your claude_desktop_config.json:
{
"mcpServers": {
"lobbywatch": {
"command": "uvx",
"args": ["lobbywatch-mcp"]
}
}
}
A full example is provided in claude_desktop_config.json.
Once connected, try prompts such as:
All tool names use the lobbywatch_ namespace prefix (since 0.2.0) to
avoid collisions with sibling portfolio servers.

/table/parlamentarier/... dataIF REST endpoint currently returns empty result sets. The server works around this by using the weekly JSON dump instead.zutrittsberechtigungen (access badges) are not populated in the "essential" dump variant used here.
