How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-opensensemap). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass

- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability56
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1101 tokens (~367/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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 →
opensensemap_area_average ~440
Average one phenomenon across all citizen science sensors (openSenseMap / senseBox network) in an area — hyperlocal neighborhood-level temperature, PM2.5/PM10 air quality, humidity, pressure or noise from many independent community stations. Give either a bounding box or a center point + radius_km. Aggregates the latest reading per sensor over the recent window client-side (the network has no fast server-side aggregation). Phenomenon names on openSenseMap are mostly German (exact sensor titles): "Temperatur" (temperature °C), "rel. Luftfeuchte" (relative humidity %), "Luftdruck" (air pressure hPa), "PM2.5" and "PM10" (particulate matter µg/m³), "Beleuchtungsstärke" (illuminance lx), "UV-Intensität" (UV µW/cm²), "Lautstärke" (noise) — the name must match the sensor title exactly (e.g. "Temperatur", not "temperature"). Example: opensensemap_area_average({ phenomenon: "PM2.5", latitude: 52.52, longitude: 13.405, radius_km: 5 })
| Name | Type | Req | Description |
|---|---|---|---|
| bbox | string | – | Bounding box as "west,south,east,north" in degrees, e.g. "13.3,52.45,13.5,52.55" (overrides center+radius) |
| latitude | number | – | Center latitude (use with longitude + radius_km, instead of bbox) |
| longitude | number | – | Center longitude |
| phenomenon | string | yes | Exact phenomenon / sensor title, e.g. "PM2.5", "PM10", "Temperatur", "rel. Luftfeuchte", "Luftdruck", "Lautstärke" |
| radius_km | number | – | Radius in km around the center, 0.1-25 (default 5) |
| window_hours | number | – | How far back to look for each sensor's latest reading, 1-24 hours (default 2) |

No examples provided.
opensensemap_box ~157
Get one openSenseMap citizen science sensor station (senseBox) by its box id — full sensor readout with latest value, unit, and measurement time per sensor (temperature, humidity, PM2.5/PM10 air quality, pressure, noise...), plus location, exposure (outdoor/indoor/mobile) and station metadata. Box ids come from opensensemap_nearby. Community-operated uncalibrated sensors. Example: opensensemap_box({ box_id: "65e8d93acbf5700007f920ca" })
| Name | Type | Req | Description |
|---|---|---|---|
| box_id | string | yes | 24-char openSenseMap box id, e.g. "65e8d93acbf5700007f920ca" |
No output schema declared.
No examples provided.
opensensemap_nearby ~449
Find citizen science sensor stations (senseBox, openSenseMap network) near a lat/lon and return their latest readings — hyperlocal temperature, humidity, air pressure, PM2.5/PM10 air quality, illuminance, UV, noise. Answers "sensor readings near me", "what does the local air quality sensor say". Community-operated uncalibrated hardware: quality varies, so cross-check outliers. Filter to one measurement type with `phenomenon` (Phenomenon names on openSenseMap are mostly German (exact sensor titles): "Temperatur" (temperature °C), "rel. Luftfeuchte" (relative humidity %), "Luftdruck" (air pressure hPa), "PM2.5" and "PM10" (particulate matter µg/m³), "Beleuchtungsstärke" (illuminance lx), "UV-Intensität" (UV µW/cm²), "Lautstärke" (noise)). Stations silent for more than 7 days are skipped unless include_stale=true. Example: opensensemap_nearby({ latitude: 52.52, longitude: 13.405, phenomenon: "PM2.5" })
| Name | Type | Req | Description |
|---|---|---|---|
| include_stale | boolean | – | Include stations whose last measurement is older than 7 days (default false) |
| latitude | number | yes | Latitude of the search center, e.g. 52.52 |
| limit | number | – | Max stations to return with full readings, 1-10 (default 5) |
| longitude | number | yes | Longitude of the search center, e.g. 13.405 |
| phenomenon | string | – | Optional filter — only stations measuring this phenomenon. Common titles: "Temperatur", "rel. Luftfeuchte", "Luftdruck", "PM2.5", "PM10", "Beleuchtungsstärke", "UV-Intensität", "Lautstärke" (matched… |
| radius_km | number | – | Search radius in km, 0.1-50 (default 10) |

What is the Opensensemap MCP server?
Opensensemap is an MCP server listed in the public MCP registry as io.github.pipeworx-io/opensensemap. openSenseMap MCP, citizen-science environmental sensor network (opensensemap.org). This page covers its npm package (@pipeworx/mcp-opensensemap).
Is the Opensensemap MCP server safe to use?
Opensensemap scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 Opensensemap MCP server expose?
Opensensemap exposes 3 tools: opensensemap_nearby, opensensemap_box, opensensemap_area_average. Their descriptions and schemas cost roughly 1,046 tokens of context every time the server is loaded.
Is the Opensensemap MCP server still maintained?
Opensensemap 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.
What licence is the Opensensemap MCP server under?
Opensensemap declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
What did VerifyMCP test on the Opensensemap MCP server?
VerifyMCP ran 16 checks on Opensensemap, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
