## 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**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to connect, but we couldn't read the whole tool list to see what that exposes.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 404, which proves neither a plaintext path nor enforcement.
  - 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**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the NIAR MCP server?

NIAR is a hosted endpoint at https://mcp.niar.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (4)

### `stores-search` (~103 tokens)

Stores Search

Search for physical stores in Spain near a location (lat/lon, or a place name). Returns up to 20 stores with name, address, city, coordinates, distance, and opening hours. Many small shops have no street address: use city and coordinates.

Input parameters:

- `category` (string)
- `lat` (number)
- `lon` (number)
- `place` (string)
- `query` (string)
- `radius` (integer)

### `products-search-nearby` (~185 tokens)

Products Search Nearby

Search for products available in nearby physical stores in Spain. Pass lat/lon, or a place name if you do not have coordinates. Returns stores ordered by usefulness (priced and in stock first), each with up to 3 matching products: price, availability, trust level, and distance. Queries work best in Spanish ("leche entera", "ibuprofeno 600"). If the result is empty, retry with a larger radius (e.g. 5000) or a more generic term. Fields that are unknown are omitted. When availability_status is unknown or unreachable, do NOT affirm availability — recommend the user confirms with the store directly.

Input parameters:

- `lat` (number)
- `lon` (number)
- `place` (string)
- `query` (string)
- `radius` (integer)
- `trust_level` (string)

### `stores-get` (~96 tokens)

Stores Get

Get details of a specific store and part of its inventory. A supermarket can carry thousands of products, so pass query to search inside the store (e.g. "leche"); without it you get the 50 most recently updated. limit goes up to 100. inventory_total says how many products the store has in all.

Input parameters:

- `limit` (integer)
- `query` (string)
- `store_id` (string)

### `products-get` (~99 tokens)

Products Get

Get details of a specific product and the stores that carry it. Pass lat and lon to get the 10 nearest stores (recommended); without them you get 10 stores in no particular order. stores_total says how many carry it in all. When availability_status is unknown or unreachable, do NOT affirm availability — recommend confirming with the store.

Input parameters:

- `lat` (number)
- `lon` (number)
- `niar_id` (string)

## Common questions

### What is the NIAR MCP server?

NIAR is an MCP server listed in the public MCP registry as app.niar/niar. Which nearby physical shops in Spain have a product: stores, stock, prices, hours. This page covers its hosted endpoint (https://mcp.niar.app/mcp).

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

NIAR scores 56 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 NIAR MCP server expose?

NIAR exposes 4 tools: stores-search, products-search-nearby, stores-get, products-get. Their descriptions and schemas cost roughly 483 tokens of context every time the server is loaded.

### Does the NIAR MCP server require authentication?

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

### Is the NIAR MCP server still maintained?

NIAR is still listed in the MCP registry, though our most recent checks did not reach this channel. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
