## Common questions

### What is the Noaa Tides MCP server?

Noaa Tides is an MCP server listed in the public MCP registry as io.github.pipeworx-io/noaa-tides. NOAA Tides & Currents MCP. This page covers its npm package (@pipeworx/mcp-noaa-tides).

### Is the Noaa Tides MCP server safe to use?

Noaa Tides scores 80 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 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 Noaa Tides MCP server expose?

Noaa Tides exposes 7 tools: stations, station_metadata, predictions, water_level, currents, and 2 more. Their descriptions and schemas cost roughly 550 tokens of context every time the server is loaded.

### Is the Noaa Tides MCP server still maintained?

Noaa Tides 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 Noaa Tides MCP server under?

Noaa Tides 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 Noaa Tides MCP server?

VerifyMCP ran 16 checks on Noaa Tides, 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.
