## 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**: 80/100
  - 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 74/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 2019 tokens (~155/item across 13 items; 11 tools + 2 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 91/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 74% 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 11 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 13 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.

### `get_sensor_readings` (~147 tokens)

Sensor readings

Readings of one sensor: raw (the last 31 days, at most 7 days a call), 5-minute means (the same windows), hourly means (the last 366 days, at most 92 days a call) or daily means (UTC days of the last 366 days, with the quality check of each day).

- `to` (string): ISO 8601 date or time, UTC; default now.

### `get_sensors_average` (~111 tokens)

Mean of a group of sensors

The mean of up to 100 sensors per 5 minutes, hour or UTC day, each sensor counted once per bucket, with the number of sensors in each bucket. Windows as in get_sensor_readings; by day at most 92 days a call.

Input parameters:

## Common questions

### What is the Atmy air quality MCP server?

Atmy air quality is an MCP server listed in the public MCP registry as ai.atmy/air-quality. PM2.5 of 300+ cities: now, history, forecast, rankings; 12 000 sensors with a quality rating. This page covers its hosted endpoint (https://api.atmy.ai/mcp).

### Is the Atmy air quality MCP server safe to use?

Atmy air quality scores 77 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 Atmy air quality MCP server expose?

Atmy air quality exposes 11 tools: search_cities, get_air_quality, get_air_quality_history, get_air_quality_monthly, get_city_forecast, and 6 more. Their descriptions and schemas cost roughly 1,621 tokens of context every time the server is loaded.

### Does the Atmy air quality MCP server require authentication?

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

### Is the Atmy air quality MCP server still maintained?

Atmy air quality is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
