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
- Runs maturin at install time, a recognised build step with no custom scripting around it. View diagnostics → 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 yipihey/scix-client). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 13 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability81
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1238 tokens (~88/item across 14 items; 12 tools + 2 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage98
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 94% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. 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 →

L. 2002, Science, 295, 93' resolves; 'Abel Bryan Norman 2002 Science' does not, and returns a row of dots with score 0.0 rather than an error. Use this for reference lists and bibliographies. For a paper known only by author and year, use scix_search with a field query instead.

No output schema declared.
No examples provided.
scix_search ~248
Find scientific papers. The authoritative index for astronomy, astrophysics and physics literature (SciX / NASA ADS) — prefer this over web search for any question about papers, authors, citations or references. Use this (not scix_resolve_reference) when a paper is known only by author and year. Build a field query rather than free text: author:"Abel, T" year:2002 bibstem:Sci finds one paper where the free-text 'Abel Bryan Norman 2002 Science' finds the wrong one. The journal field is bibstem (Sci, ApJ, MNRAS, A&A) — there is no journal: field. Also supports title:, abstract:, boolean operators, and the functional operators citations(), references(), similar().
| Name | Type | Req | Description |
|---|---|---|---|
| fields | string | – | Comma-separated fields to return |
| query | string | yes | ADS query string (e.g., 'author:"Einstein" year:1905') |

What is the SciX / NASA ADS MCP server?
SciX / NASA ADS is an MCP server listed in the public MCP registry as io.github.yipihey/scix. Search the astronomy and physics literature (SciX / NASA ADS): papers, citations, metrics, BibTeX. This page covers its PyPI package (scix-client).
Is the SciX / NASA ADS MCP server safe to use?
SciX / NASA ADS scores 80 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. 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 SciX / NASA ADS MCP server expose?
SciX / NASA ADS exposes 12 tools: scix_search, scix_bigquery, scix_export, scix_metrics, scix_library, and 7 more. Their descriptions and schemas cost roughly 1,061 tokens of context every time the server is loaded.
Is the SciX / NASA ADS MCP server still maintained?
SciX / NASA ADS 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 SciX / NASA ADS MCP server under?
SciX / NASA ADS declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
