## 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)

## Common questions

### What is the Nass MCP server?

Nass is an MCP server listed in the public MCP registry as io.github.pipeworx-io/nass. NASS MCP, USDA National Agricultural Statistics Service (Quick Stats). This page covers its npm package (@pipeworx/mcp-nass).

### Is the Nass MCP server safe to use?

Nass scores 82 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 Nass MCP server expose?

Nass exposes 5 tools: nass_query, nass_crop_production, nass_prices, nass_livestock, nass_crop_progress. Their descriptions and schemas cost roughly 1,033 tokens of context every time the server is loaded.

### Is the Nass MCP server still maintained?

Nass 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 Nass MCP server under?

Nass 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 Nass MCP server?

VerifyMCP ran 16 checks on Nass, 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.
