## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

### What tools does the Urlhaus MCP server expose?

Urlhaus exposes 4 tools: lookup_url, lookup_host, get_recent, lookup_payload. Their descriptions and schemas cost roughly 274 tokens of context every time the server is loaded.

### Is the Urlhaus MCP server still maintained?

Urlhaus 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 Urlhaus MCP server under?

Urlhaus 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 Urlhaus MCP server?

VerifyMCP ran 16 checks on Urlhaus, 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.
