MCP tools · 3 exposed · ~519 tokens

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 →

Tool Tokens
check_dependencies ~118

Verify many npm or PyPI packages at once — use this before writing a package.json or requirements.txt, or handing a dependency list to a user. All names must belong to one ecosystem per call. Results are sorted worst-first so anything hallucinated or dangerous surfaces at the top. Read-only; batches registry requests and caches adoption figures, so 50 names take a few seconds.

namesarrayyesPackage names to verify (max 50), without version suffixes.

totalintegeryes

No examples provided.

check_install_command ~239

Verify the packages a shell command would install or execute, before running it: `npm install …`, `npx …`, `pnpm add`, `yarn add`, `bun add`, `pip install`, `uv add`, `poetry add` and similar, including behind `sudo`, `&&` chains and `sh -c`. Extracts the package names (npm and PyPI at once), checks each against its registry, and returns them worst-first. A command that installs nothing by name (a bare `npm install` from a lockfile, `git`, `npm test`, or `npx <bin>` of a tool already in node_modules) returns total 0 and costs no network call — use check_dependencies on the manifest in that case. Read-only.

NameTypeReqDescription
commandstringyesThe exact shell command about to run, e.g. "npm install express crossenv" or "pip install -U requests".
cwdstringDirectory the command will run in. Lets "npx <bin>" of an already-installed tool be recognised as fetching nothing. Defaults to the server's working directory.

check_package ~162

Verify a single npm or PyPI package before installing, importing, or recommending it. Returns whether it actually exists, and flags slopsquatting (a low-adoption package impersonating a popular one), names npm removed for malware, install-time scripts, deprecation, and abandonment. Call this whenever you are about to introduce a dependency you have not verified in this session. Read-only; one or two requests to the public registry. A verdict of UNKNOWN means the registry did not answer — retry, never assume safe.

NameTypeReqDescription

Common questions

What is the io.github.hxckya/pkgtruth MCP server?

io.github.hxckya/pkgtruth is an MCP server listed in the public MCP registry as io.github.hxckya/pkgtruth. Catches hallucinated and slopsquatted npm and PyPI packages before an agent installs them. This page covers its npm package (pkgtruth).

Is the io.github.hxckya/pkgtruth MCP server safe to use?

io.github.hxckya/pkgtruth scores 91 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 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 io.github.hxckya/pkgtruth MCP server expose?

io.github.hxckya/pkgtruth exposes 3 tools: check_package, check_dependencies, check_install_command. Their descriptions and schemas cost roughly 519 tokens of context every time the server is loaded.

Is the io.github.hxckya/pkgtruth MCP server still maintained?

io.github.hxckya/pkgtruth is still listed as active in the MCP registry. We last reached this channel on 21 September 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 io.github.hxckya/pkgtruth MCP server under?

io.github.hxckya/pkgtruth declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
