clio-hdf5

clio-hdf5 is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from iowarp/clio-kit. Its token cost is not measured, scanned A, original, BSD-3-Clause.

An MCP server configuration for launching the HDF5 service from the Clio toolkit. HDF5 is a file format commonly used to store large, structured scientific or technical datasets.

In plain words
What is it for?
It is for connecting an agent or MCP client to the Clio HDF5 server; the input does not provide enough detail to name more specific jobs.
Why use it?
It lets an MCP client start the configured HDF5 server as part of a tool setup. The supplied information does not describe the server's individual operations.

Written for no agent in particular: it speaks MCP, so any client can run it. Also seen: listed in a Claude config.

One of 24 entries in claude_desktop_config.json — they are configured in one file and arrive together.

Security

Grade A, and why

clio-hdf5 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
