Abgeordnetenwatch MCP

A Model Context Protocol server over the open Abgeordnetenwatch API (CC0). It gives an AI assistant live, source-linked transparency data on German MPs: roll-call voting behaviour, declared side-jobs / outside income, committee memberships, parties, parliaments, and election programs.

Germany only — Bundestag and Landtage. No API key required.

Run

npm install
npm start          # http://localhost:3000/mcp   (health: /health, catalog: /info)
npm test           # vitest
npm run dev        # watch mode

Config is env-driven (all optional) — see .env.example. The public CC0 API needs no key; the server enforces its own ~30 req/min limiter and caches responses ~10 min.

Design notes

• Every read is filtered and bounded (range_end, capped at 100). The API has no aggregate endpoints; roll-call tallies are the one wide read (≤1000 votes, aggregated server-side into counts).

• Income is a level 1–10, never an exact euro sum (level 1 = up to 1.000 €, level 10 = over 250.000 €).

• The polls endpoint 500s on sort_by=id (unlike votes/mandates) — polls are sorted by field_poll_date.

• Client logic mirrors the Abgeordnetenwatch tools embedded in the Bundestag Wrapped MCP; this repo is the standalone, full-surface server. DIP and Abgeordnetenwatch share no id — bridge by name.
