Available tools 10

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

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_changes

List German cities that changed their Hundesteuer (dog tax) rate in a given year — the fresh-news angle for the annual city comparison. Only 2026 is curated, and it is the default: 14 of the covered cities changed their rate, led by Köln (174 EUR), Lübeck (156 EUR), Lünen (156 EUR). Also returns outlook_2027: 5 cities that have announced or resolved an increase for 2027 but are NOT yet charging it — announced and in force are kept apart deliberately. Every entry checked individually against the municipal statute.

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.

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. Only 2026 is curated, and it is the default: 12 cities changed their rate, led by Potsdam (25 %), Borkum (22 %), Stuttgart (20 %). Every entry checked individually against the municipality's own statute.

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.

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 10 tools, read directly from the server on our last check. Among them: hundesteuer_by_state, hundesteuer_changes, hundesteuer_lookup, hundesteuer_ranking, list_datasets, pfaendung_calc and 4 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 hundesteuer and zweitwohnungsteuer. 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 91 of 91 checks got a reply (100.0%), average response time 133 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 in the form 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 10 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 133 ms on average, which is faster than 86% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
