## 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 2026-09-27.

- **Endpoint Security**: 66/100
  - 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 5 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 is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 78/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 596 tokens (~119/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 40/100
  - Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 93/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 78% 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 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (5)

### `get_rent` (~145 tokens)

Get Barcelona rent for an area

Current average rent and sale price for one Barcelona neighbourhood or district, from contracts actually registered with the Catalan government — not listing or asking prices. Accepts a neighbourhood name, a district name or a URL slug. Returns euros per m² per month, an estimated monthly rent for a reference flat, the sale price per m², gross rental yield where both figures describe the same quarter, and the quarter each figure comes from.

Input parameters:

- `area` (string, required): Neighbourhood or district, e.g. "la Vila de Gràcia", "Eixample", "pedralbes"
- `sqm` (number): Flat size for the monthly estimate (default 75)

### `compare_areas` (~73 tokens)

Compare Barcelona areas

Compare registered rent and sale prices across two or more Barcelona neighbourhoods or districts, cheapest first. Use when someone is choosing between places to live or asking which is more expensive. Same official source as get_rent.

Input parameters:

- `areas` (array, required): Two to ten neighbourhood or district names
- `sqm` (number)

### `rent_trend` (~89 tokens)

Barcelona rent over time

The quarterly series of registered rents for one Barcelona neighbourhood or district, and how much it has changed over the window. Use for questions about whether rents are rising or falling in a specific area. Figures run from 2014 for neighbourhoods and 2000 for districts.

Input parameters:

- `area` (string, required)
- `since` (integer): First year to include (default: the last 5 years)

### `find_areas` (~71 tokens)

Find Barcelona areas within a budget

Which Barcelona neighbourhoods a monthly budget actually reaches, cheapest first, based on registered rents rather than advertised prices. Use when someone says what they can afford and wants to know where to look.

Input parameters:

- `budget` (number, required): Monthly budget in euros
- `sqm` (number): Flat size (default 75)

### `barri_character` (~138 tokens)

What a Barcelona neighbourhood is like

What a Barcelona neighbourhood is actually like, from the city's own published measures: how much street commerce it has, how much road traffic noise reaches residents at night, how steep its streets are, how many households have a child, and how many residents hold a foreign passport. Each figure comes with the city median and the barri's percentile among all 73. Use for questions about whether somewhere is quiet, lively, hilly, family-heavy or international — not for questions about price. None of these explains what a barri costs.

Input parameters:

- `area` (string, required): Neighbourhood name, e.g. "Gràcia" or "el Raval"
