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. How we score → Why this is hard to score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to connect, but we couldn't read the whole tool list to see what that exposes. View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 404, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

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.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
products-get Products Get ~99
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.
| Name | Type | Req | Description |
|---|---|---|---|
| lat | number | – | – |
| lon | number | – | – |
| niar_id | string | – | – |
No output schema declared.
No examples provided.
products-search-nearby Products Search Nearby ~185
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.

stores-get Stores Get ~96
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.

stores-search Stores Search ~103
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.

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.

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?
