## 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 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 60/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1922 tokens (~320/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 53/100
  - Stability observed for 16 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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 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.

Each figure has its unit, period, level (municipality, or province when the place has none), source credit and date, and station or point of interest with distance. Only places whose flatin.es page is published get figures; every answer links the flatin.es pages.

### `non_resident_tax` (~353 tokens)

Spanish non-resident income tax (IRNR, modelo 210)

Yearly IRNR of a non-resident owner of a Spanish home: imputed income (1.1 % or 2 % of the cadastral value for days not let) and rental income (EU/EEA: 19 % net of expenses; others: 24 % on gross rent).

### `place_facts` (~160 tokens)

What sets a Spanish municipality apart, with for/against rules

For one municipality published on flatin.es (currently the provinces of Alicante, Málaga, Valencia, Murcia; comparisons use all of Spain): the indicators where it clearly differs from its province, Spain or its neighbours (rank, provincial median, Spanish percentile — only when at least 80% of applicable places have data), and fixed for/against rules on published data (prices, affordability in years of income, rent share of income, empty homes, crime per resident and with seasonal population, distances, fibre). Every number has its period and source. Not an opinion.

Input parameters:

- `place` (string, required): A municipality of the provinces of Alicante, Málaga, Valencia or Murcia: name, slug, 'province/municipality' or 5-digit INE code.
