## 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 2026-10-18.

- **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**: 57/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 3112 tokens (~311/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 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 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

### `sea_views` (~351 tokens)

Homes with a sea view (France)

The sale addresses around a place whose sun goes down (or comes up) into the sea, month by month, with how far the shore is and their latest sale. Worked out from OpenStreetMap for France's sale addresses within 300 m of the coast: the sun's direction must reach the shore past no building but the home's own, no wood, no dune but a narrow one at the door, no cliff upwards, then cross open water. A ground-level estimate: floors, trees and relief are not known. An address missing here may still see the sea from upstairs; say so rather than that it has no view. The same view shows as sea_view on the sales of sales_at_address, recent_sales and appraise_listing.

Input parameters:

- `address` (string): Street address with its postcode or city (e.g. "17 rue Gambey, 75011 Paris"), located where its sales were recorded (else its street's). Ignored when lat and lng are given.

- `radius_m` (integer): Radius in metres (default 1000, at most 5000).
- `sun` (string): Only addresses that see the sun set (sunset) or rise (sunrise) into the sea; default any.

### `appraise_listing` (~382 tokens)

Appraise a listing

Compares a French listing's asking price with recent recorded sales (DVF) of the same type and a similar size around it (the smallest radius with enough of them): estimate with its interquartile range, gap and verdict, closest comparables (sales over 2.5 times off the median price per m² are left out as no market price), a headline such as "12 % au-dessus du marché", local price trend, the commune's main crime rates against France, its rent for the type (monthly rent for the floor area, gross yield at the asking price), its share of passoires thermiques (DPE F or G) for the type, its natural risks, its local tax rates (taxe foncière, waste tax, taxe d'habitation on second homes), its home internet (fibre and wired speeds), each mobile operator's 4G coverage level at the address (mobile_4g) and their antennas, amenities within 500 m, and the address's sea view when it has one.

Input parameters:

- `address` (string): Street address with its postcode or city (e.g. "17 rue Gambey, 75011 Paris"), located where its sales were recorded (else its street's). Ignored when lat and lng are given.

## Common questions

### What is the CaLesVaut MCP server?

CaLesVaut is an MCP server listed in the public MCP registry as fr.calesvaut/calesvaut. Is this listing too expensive? French property sales (DVF), crime, rents, risks, schools. This page covers its hosted endpoint (https://calesvaut.fr/mcp).

### Is the CaLesVaut MCP server safe to use?

CaLesVaut scores 68 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

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

CaLesVaut exposes 10 tools: find_place, property_prices, sales_at_address, recent_sales, crime_stats, and 5 more. Their descriptions and schemas cost roughly 2,796 tokens of context every time the server is loaded.

### Does the CaLesVaut MCP server require authentication?

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

### Is the CaLesVaut MCP server still maintained?

CaLesVaut is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
