## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-26.

- **Endpoint Security**: 51/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 988 tokens (~123/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 83/100
  - Stability observed for 25 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (8)

### `municipality_search` (~104 tokens)

Finds Swiss municipalities by name fragment or postcode. Returns the BFS id, name, canton and postcodes for each match. The BFS id is the key every other tool here takes.

Input parameters:

- `limit` (integer): Maximum matches to return (1-50).
- `q` (string): Name fragment, e.g. "Uster". Case-insensitive.
- `zip` (string): Four-digit Swiss postcode, e.g. "8308" (which alone spans three Gemeinden).

### `tax_lookup` (~130 tokens)

Calculates the annual Swiss income tax for one municipality and one household profile, split into federal, cantonal and municipal parts. The figures come from the federal tax administration's calculation for the given gross income.

Input parameters:

- `bfsId` (integer, required): Municipality BFS id, from municipality_search.
- `children` (integer): Number of dependent children.
- `confession` (string): Church-tax affiliation.
- `income` (integer, required): Gross annual household income in CHF.
- `relationship` (string): Marital status used for the tariff.
- `year` (integer): Tax year. Defaults to the year this installation is configured for.

### `municipality_detail` (~132 tokens)

Returns the tax picture for one municipality relative to a stated current home: the annual difference, the tax multiplier, and the multi-year trend where past years are known.

Input parameters:

- `bfsId` (integer, required): The municipality to describe.
- `children` (integer): Dependent children.
- `confession` (string): Church-tax affiliation.
- `currentBfsId` (integer, required): BFS id of the current home, which every difference is measured against.
- `income` (integer, required): Gross annual income in CHF.
- `relationship` (string): Marital status.
- `years` (integer): How many years of history to include.

### `favorable_municipalities` (~245 tokens)

Ranks municipalities that are cheaper than, or within CHF 1000/yr of, a stated current home, by annual tax saving — municipalities near-identical in cost are included deliberately, not filtered out. Answered from cached figures only, so the ranking may be partial; the response states how many candidates were covered. Pass `near` (a town or station name) and `radiusKm` to keep only places around where the household lives or works; an unrecognised place is reported, not silently ignored.

Input parameters:

- `children` (integer): Dependent children.
- `confession` (string): Church-tax affiliation.
- `currentBfsId` (integer, required): BFS id of the current home.
- `currentRooms` (number): Size of the current home in rooms, used for the rent comparison.
- `income` (integer, required): Gross annual income in CHF.
- `near` (string): Town or station name to search around, e.g. "Winterthur". Not a postcode.
- `radiusKm` (integer): Distance from `near` in km (default 20). Ignored without `near`.
- `relationship` (string): Marital status.

### `listing_search` (~110 tokens)

Lists apartments currently advertised in one municipality, cheapest first, with the local median asking rent. Indicative figures for browsing only: they come from a portal feed and are not verified against the listing page.

Input parameters:

- `bfsId` (integer, required): Municipality to search in.
- `limit` (integer): Maximum listings to return (1-25).
- `rooms` (number): Preferred size in rooms; re-ranks, never filters.
- `surface` (number): Preferred living space in m²; re-ranks.

### `commute_time` (~69 tokens)

Returns the public-transport journey time in minutes between two Swiss places, using the national timetable.

Input parameters:

- `from` (string, required): Origin as a place or station name, e.g. "Uster". Not a postcode on its own.
- `to` (string): Destination as a place or station name.

### `commute_cost` (~90 tokens)

Estimates the monthly cost in CHF of commuting between two Swiss places, as a transit-pass estimate priced from Swiss regional fare-zone data. Some pricing regimes are approximations rather than an exact tariff.

Input parameters:

- `from` (string, required): Origin as a place or station name, e.g. "Feusisberg". Not a postcode on its own.
- `to` (string): Destination as a place or station name.

### `rent_benchmark` (~108 tokens)

Reports the Swiss Federal Statistical Office's average monthly rent for a municipality, optionally for a given apartment size in rooms. BFS does not publish rent below canton level except for 10 named cities, so the figure may describe the CANTON rather than the municipality itself; the response states which.

Input parameters:

- `bfsId` (integer, required): Municipality BFS id, from municipality_search.
- `rooms` (number): Apartment size in rooms, e.g. 3.5. Omit for the overall average.

### What tools does the Zügle MCP server expose?

Zügle exposes 8 tools: municipality_search, tax_lookup, municipality_detail, favorable_municipalities, listing_search, and 3 more. Their descriptions and schemas cost roughly 988 tokens of context every time the server is loaded.

### Does the Zügle MCP server require authentication?

No. We connected to Zügle without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Zügle MCP server still maintained?

Zügle is still listed as active in the MCP registry. We last reached this channel on 26 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
