Each quoted sentence is the first sentence of the publisher’s own description. The kind of tool and the “changes data” mark are our AI model’s reading of that description, not something we tested: two differently worded runs had to agree, otherwise no label is shown, and nobody has checked them by hand. A tool without the “changes data” mark is described as only reading, searching or calculating, or the two runs did not agree. No tool was called. Read the publisher’s full description before relying on it. Inputs are the parameters in the tool's own input schema: name, declared type, whether it is required, and the first sentence of its description. Read 2026-10-23.
How well are its tools described?
Features #4 and #5
How clearly this server's own tool descriptions say what a tool does, and how consistent its tool list is. The first part is an AI model's yes/no reading of each description; the second part is counted. We do not turn it into a grade.

AI reading: easy to mix up
No pair found.
The AI items cover 15 of 15 tools: for a tool where two differently worded runs disagreed, that item is left out. They were not checked by hand, and no tool was called. “Easy to mix up” means two tools whose names or descriptions overlap without saying how they differ; the AI found none. We do not rate whether the tool set is complete or whether side effects are spelled out, because our AI reading of those was not reliable enough.

Does the registry listing match what we found?
Feature #6The registry verifies a package once, when it is published, and does not re-check it. A difference below is about the listing, not a judgement of the publisher.

Common questions about dev.danielhan.asolens/mcp
Answered from the data aboveIs dev.danielhan.asolens/mcp safe to install?
We do not rate servers as safe or unsafe. 4 of its 6 applicable record checks are met (facts from public records, each listed on this page). What the records show: The listed version is the latest stable release. The package itself has no known vulnerability (OSV.dev). Its full dependency tree has no known advisory. 1 of its tools describes changing data (our AI model's reading of the descriptions). These are facts with their sources on this page, not a safety guarantee, and we did not run its tools.
Is dev.danielhan.asolens/mcp free to use?
Its website (asolens.danielhan.dev/) describes a free pricing model. This is an AI-classified reading of the page on 2026-10-23, so check the page itself before relying on it.
Has dev.danielhan.asolens/mcp been security tested?
Partly. 2 of the 12 checks that apply to it were exercised. We started the package in an isolated sandbox and read what it declares, but this test round was read-only, so its tools were not called. No security verdict is published before verification.
What can dev.danielhan.asolens/mcp do?
It lists 15 tools. In our AI model's reading of their descriptions (two runs had to agree, nobody checked it by hand), they include tools that read or search and create or change data. We did not call any tool, so this describes the text, not the behaviour.
Can dev.danielhan.asolens/mcp change or delete data?
1 of its tools says in its description that it creates, edits, deletes, sends or runs something (our AI model's reading). We did not call any tool, so we cannot say what actually happens.
Is the listed version current?
Yes. The registry lists 0.4.1, the latest stable release on npm.

Reference
How is it classified?
18 fields
One value per field, each with its source. Fields written by AI models are marked. A field with no value says why.
“Free. No ASOLens account. It runs on your machine and keeps its history in a local SQLite file. Needs Node.js 22.13 or newer.”
“Not stated” means the source did not state it; “does not apply” means it does not apply to this kind of server; “our limit” means our own lookup failed. A linked value opens the directory filtered to the same value.
