No change was recorded against any check on this day. Stability & Change Management went from 80 to 83. That category is still filling its 30-day observation window: 24 days of observed history at the previous scan, 25 at this one. The score rises as the window fills, whether or not the server changes.
Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

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 →

What is the io.github.andretaki/hazmat-cfr-mcp server?
io.github.andretaki/hazmat-cfr-mcp is listed in the public MCP registry as io.github.andretaki/hazmat-cfr-mcp. Complete 49 CFR 172.101 hazmat table lookup with special-provision decoding, cited to eCFR. This page covers its npm package (hazmat-cfr-mcp).
Is the io.github.andretaki/hazmat-cfr-mcp server safe to use?
io.github.andretaki/hazmat-cfr-mcp scores 85 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 6 November 2026. It declares no install or post-install scripts. 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.andretaki/hazmat-cfr-mcp server expose?
io.github.andretaki/hazmat-cfr-mcp exposes 11 tools: lookup_hazmat_entry, classify_shipping_description, validate_basic_hazmat_description, get_label_requirements, check_basic_segregation, and 6 more. Their descriptions and schemas cost roughly 918 tokens of context every time the server is loaded.
Is the io.github.andretaki/hazmat-cfr-mcp server still maintained?
io.github.andretaki/hazmat-cfr-mcp is still listed as active in the MCP registry. We last reached this channel on 6 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 io.github.andretaki/hazmat-cfr-mcp server under?
io.github.andretaki/hazmat-cfr-mcp 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 io.github.andretaki/hazmat-cfr-mcp server?
VerifyMCP ran 16 checks on io.github.andretaki/hazmat-cfr-mcp, 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.
