Category Maps and Location
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-n2yo). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 1 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability60
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 758 tokens (~252/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 →
get_positions ~235
Track where a satellite is right now (or in the next few seconds): get its live latitude, longitude, altitude, and look-angles (azimuth/elevation) from an observer on Earth. Use this to answer "where is the ISS right now?" (NORAD id 25544) or to locate any satellite by NORAD id. Example: get_positions({ norad_id: 25544, lat: 40.71, lon: -74.0 }).
| Name | Type | Req | Description |
|---|---|---|---|
| _apiKey | string | – | Optional — your own N2YO API key for higher limits; omit to use the shared Pipeworx key. |
| altitude | number | – | Observer altitude in meters above sea level (default 0). |
| lat | number | yes | Observer latitude in decimal degrees. |
| lon | number | yes | Observer longitude in decimal degrees. |
| norad_id | number | yes | NORAD catalog id of the satellite, e.g. 25544 for the ISS, 20580 for Hubble. |
| seconds | number | – | Number of future seconds of positions to predict (default 2, max 300). |
No output schema declared.
No examples provided.
get_visual_passes ~246
Find when a satellite will be visible to the naked eye overhead from an observer location (visual passes = bright, sunlit passes against a dark sky). Returns start/max/end times, elevation, azimuths, brightness magnitude, and duration. Use this for "when can I see the ISS pass over?" Example: get_visual_passes({ norad_id: 25544, lat: 40.71, lon: -74.0 }).
| Name | Type | Req | Description |
|---|---|---|---|
| _apiKey | string | – | Optional — your own N2YO API key for higher limits; omit to use the shared Pipeworx key. |
| altitude | number | – | Observer altitude in meters above sea level (default 0). |
| days | number | – | Number of days ahead to search for passes (default 5, max 10). |
| lat | number | yes | Observer latitude in decimal degrees. |
| lon | number | yes | Observer longitude in decimal degrees. |
| min_visibility | number | – | Minimum visible duration in seconds for a pass to be returned (default 300). |
| norad_id | number | yes | NORAD catalog id of the satellite, e.g. 25544 for the ISS. |
No output schema declared.
No examples provided.
whats_above ~223
List what satellites are currently above a location on Earth, within a given radius of the observer's zenith. Use this to answer "what satellites are overhead right now?" Optionally filter by category (e.g. 52 = Starlink, 18 = amateur radio, 1 = brightest). Example: whats_above({ lat: 40.71, lon: -74.0 }).
| Name | Type | Req | Description |
|---|---|---|---|
| _apiKey | string | – | Optional — your own N2YO API key for higher limits; omit to use the shared Pipeworx key. |
| altitude | number | – | Observer altitude in meters above sea level (default 0). |
| category | number | – | N2YO category filter: 0 = all (default), 18 = amateur radio, 52 = Starlink, 1 = brightest. |
| lat | number | yes | Observer latitude in decimal degrees. |
| lon | number | yes | Observer longitude in decimal degrees. |
| radius | number | – | Search radius in degrees from the observer zenith (default 70, max 90). |
No output schema declared.

How do I install the N2yo MCP server?
N2yo runs locally as an npm package, launched with npx -y @pipeworx/mcp-n2yo. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the N2yo MCP server?
N2yo is an MCP server listed in the public MCP registry as io.github.pipeworx-io/n2yo. N2YO MCP, wraps the N2YO Satellite Tracking REST API (n2yo.com). This page covers its npm package (@pipeworx/mcp-n2yo).
Is the N2yo MCP server safe to use?
N2yo 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 N2yo MCP server expose?
N2yo exposes 3 tools: get_positions, get_visual_passes, whats_above. Their descriptions and schemas cost roughly 704 tokens of context every time the server is loaded.
Is the N2yo MCP server still maintained?
N2yo 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 N2yo MCP server under?
N2yo 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 N2yo MCP server?
VerifyMCP ran 16 checks on N2yo, 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.
