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-sciencebase). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 0 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability78
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 376 tokens (~125/item across 3 items; 3 tools + 0 resources), lean.Pass
- 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_item ~103
Get a single ScienceBase catalog item by id — full summary, categories, types, dates, contacts, web links, and attached files (download URLs). e.g. id "58f8be37e4b0b7ea5452260e". Keyless.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | A ScienceBase item id, e.g. "58f8be37e4b0b7ea5452260e" (from search_items results). |
No output schema declared.
No examples provided.
item_children ~93
List the child items of a ScienceBase catalog item. The catalog is hierarchical — collections and folders contain sub-items (use get_item to check has_children). Keyless.

What is the Sciencebase MCP server?
Sciencebase is an MCP server listed in the public MCP registry as io.github.pipeworx-io/sciencebase. USGS ScienceBase catalog MCP. This page covers its npm package (@pipeworx/mcp-sciencebase).
Is the Sciencebase MCP server safe to use?
Sciencebase scores 85 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 Sciencebase MCP server expose?
Sciencebase exposes 3 tools: search_items, get_item, item_children. Their descriptions and schemas cost roughly 323 tokens of context every time the server is loaded.
Is the Sciencebase MCP server still maintained?
Sciencebase 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 Sciencebase MCP server under?
Sciencebase 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 Sciencebase MCP server?
VerifyMCP ran 16 checks on Sciencebase, 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.
