## 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 2026-08-04.

- **Endpoint Security**: 57/100
  - 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 1 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.
  - 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**: 82/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 568 tokens (~81/item across 7 items; 1 tools + 6 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability check failed: schema churn in the 9 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 1 additions.
- **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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `plan_optimal_shopping_route` (~362 tokens)

Plan optimal grocery and drug store shopping trip

Plans the optimal shopping trip for a given list and starting location in Germany. Answers 'where should I go to buy this list, and is the trip worth it?' — not 'what's on offer near me'. Matches each item on the list to the best current offer across German supermarkets and drug stores (REWE, Aldi, Lidl, Penny, Netto, Norma, Edeka, DM, Rossmann, Mueller), then computes the cheapest realistic route by weighing product prices against travel distance and shopping time. Returns the chosen store(s), the per-item picks with live prices, the trip's savings and a worth-it verdict, and a shareable interactive grocery list. Supports car, bicycle, and pedestrian travel modes. For corridor trips (A-to-B), supply 'end_location' to route stores along the way.

Input parameters:

- `end_location`: Optional destination location if not a round trip
- `hour_cost`: Time cost penalty in EUR per hour (defaults to 12.0)
- `items` (string, required): The shopping list in natural language (e.g. '3x milk, eggs, bread')
- `km_cost`: Travel cost penalty per kilometer (forced to 0.0 for bicycle/pedestrian)
- `location` (string, required): Starting location (ZIP code, city, or address in Germany)
- `max_radius_km`: Maximum search radius in kilometers (defaults: car=15km, bicycle=5km, pedestrian=2km)
- `max_stores` (integer): Maximum number of store stops to allow in the route (default: 100)
- `shopping_time_per_store`: Base shopping minutes spent per store (defaults to 10)
- `travel_mode` (string): Travel mode to use

Output parameters:

- `result` (string)
