Available tools 9

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

zweitwohnungsteuer
zweitwohnungsteuer_by_state
Average German second-home tax (Zweitwohnungsteuer) rate in percent per Bundesland (federal state), aggregated over the levying cities with a computable rate — the data behind the Deutschlandkarte. Answers 'which German state has the highest/lowest second-home tax'. Note: a mean over cities, not an official state rate (the tax is municipal).
zweitwohnungsteuer_changes
List German cities that changed (raised or newly introduced) their Zweitwohnungsteuer in a given year — the fresh-news angle. Defaults to 2026 (Stuttgart, Chemnitz, Heidelberg doubled to 20%, etc.).
zweitwohnungsteuer_lookup
Look up the German second-home tax (Zweitwohnungsteuer) for a city: whether the city levies it, the rate and its basis (net cold rent etc.), the rank among cities, official source and Stand. Optionally pass a monthly cold rent to get the annual tax. Returns state = keine_steuer | berechenbar | sondermodell.
zweitwohnungsteuer_ranking
Ranking of German cities by Zweitwohnungsteuer rate: highest or lowest, plus the average, count with a computable rate, and count of cities with no second-home tax.
hundesteuer
hundesteuer_by_state
Average German dog tax (Hundesteuer, first dog per year) per Bundesland (federal state), aggregated over the covered largest cities — the data behind the Deutschlandkarte. Answers 'which German state has the highest/lowest dog tax'. Note: a mean over cities, not an official state rate (the tax is municipal).
hundesteuer_lookup
Look up the German dog tax (Hundesteuer) for a city: annual rate for one or more dogs, listed-dog (Listenhund) surcharge, the city's pricing model, its rank among the largest cities, plus the official source and Stand. Rates verified against each municipal Satzung.
hundesteuer_ranking
Ranking of German cities by Hundesteuer (first dog, per year): most expensive or cheapest, plus the national average across the covered cities.
datasets
list_datasets
List the available hand-verified German municipal tax/fee datasets (Hundesteuer, Zweitwohnungsteuer, Pfändung), their coverage, source sites and refresh cadence. Call this first to see what you can query.
pfaendung
pfaendung_calc
Compute the attachable portion of monthly net income under German §850c ZPO (Pfändung / wage garnishment), using the current official Pfändungsfreigrenzenbekanntmachung. Returns attachable amount, remaining amount, exempt base and the P-Konto base. Informational, not legal advice.

German Tax Data — questions

Answers built from our own checks of this server.

What can German Tax Data do?
It exposes 9 tools, read directly from the server on our last check. Among them: hundesteuer_by_state, hundesteuer_lookup, hundesteuer_ranking, list_datasets, pfaendung_calc, zweitwohnungsteuer_by_state and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is German Tax Data mostly used for?
Its tools cluster around zweitwohnungsteuer and hundesteuer. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is German Tax Data working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 146 ms. The bar chart above shows every period we have measured.
How do I connect German Tax Data?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does German Tax Data need an API key?
No. German Tax Data completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is German Tax Data?
It answers our handshake in 146 ms on average, which is faster than 74% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
