## Common questions

### What is the io.github.mrfentmen/hashid-mcp server?

io.github.mrfentmen/hashid-mcp is listed in the public MCP registry as io.github.mrfentmen/hashid-mcp. Identify hash types offline: match a hex or crypt string against known algorithms and lengths. This page covers its npm package (@mrfentmen/hashid-mcp).

### Is the io.github.mrfentmen/hashid-mcp server safe to use?

io.github.mrfentmen/hashid-mcp scores 68 out of 100 on VerifyMCP. We recorded 1 known advisory against it as of 5 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.mrfentmen/hashid-mcp server expose?

io.github.mrfentmen/hashid-mcp exposes 3 tools: identify_hash, hash_details, hash_lengths. Their descriptions and schemas cost roughly 145 tokens of context every time the server is loaded.

### Is the io.github.mrfentmen/hashid-mcp server still maintained?

io.github.mrfentmen/hashid-mcp 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 io.github.mrfentmen/hashid-mcp server under?

io.github.mrfentmen/hashid-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.mrfentmen/hashid-mcp server?

VerifyMCP ran 16 checks on io.github.mrfentmen/hashid-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.
