## 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)

Scored 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-usda-soil).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 7 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 581 tokens (~193/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (3)

### `usda_soil_mapunit_at_point` (~175 tokens)

The USDA-NRCS SSURGO soil map unit at one latitude/longitude in the United States — map unit key (mukey), symbol, the official map unit name ("Terril-Urban land complex, 2 to 5 percent slopes"), its acreage, and the soil survey area it belongs to. AUTHORITATIVE for "what soil is on this parcel" in the US: field-surveyed, not modelled. Keyless. Pass the mukey to usda_soil_components for the soil series and their properties.

Input parameters:

- `lat` (number, required): Latitude in decimal degrees, WGS84 (e.g. 41.6).
- `lon` (number, required): Longitude in decimal degrees, WGS84, negative in the US (e.g. -93.6).

### `usda_soil_components` (~164 tokens)

The soil components inside one USDA SSURGO map unit — each named soil series with its percentage of the unit, official taxonomic class, drainage class, slope range, hydrologic soil group, land capability class and runoff potential. Answers "what soil series is this and how does it drain/behave". Keyless. Get the mukey from usda_soil_mapunit_at_point.

Input parameters:

- `include_horizons` (boolean): Also return the soil horizons (depth layers) for each component with sand/silt/clay percentages, organic matter, pH and available water capacity. Default false.
- `mukey` (string, required): SSURGO map unit key, e.g. "412898". From usda_soil_mapunit_at_point.

### `usda_soil_query` (~186 tokens)

Run a read-only SQL SELECT against the USDA-NRCS Soil Data Access database (SSURGO) — the full US soil survey schema: legend, mapunit, component, chorizon, cointerp, plus the SDA_ spatial helper functions such as SDA_Get_Mukey_from_intersection_with_WktWgs84. Use for anything the point and component tools do not cover: soil series by county, prime farmland acreage, drainage class distributions, crop yield indices. Keyless.

Input parameters:

- `sql` (string, required): A T-SQL SELECT, e.g. "SELECT TOP 10 m.muname, m.muacres FROM mapunit m INNER JOIN legend l ON l.lkey = m.lkey WHERE l.areasymbol = 'IA153' ORDER BY m.muacres DESC". SELECT only. Use TOP n rather than…

## Common questions

### What is the Usda Soil MCP server?

Usda Soil is an MCP server listed in the public MCP registry as io.github.pipeworx-io/usda-soil. USDA-NRCS Soil Data Access over SSURGO, the field-surveyed US soil map, the soil at any US… This page covers its npm package (@pipeworx/mcp-usda-soil).

### Is the Usda Soil MCP server safe to use?

Usda Soil scores 79 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 Usda Soil MCP server expose?

Usda Soil exposes 3 tools: usda_soil_mapunit_at_point, usda_soil_components, usda_soil_query. Their descriptions and schemas cost roughly 525 tokens of context every time the server is loaded.

### Is the Usda Soil MCP server still maintained?

Usda Soil 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 Usda Soil MCP server under?

Usda Soil 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 Usda Soil MCP server?

VerifyMCP ran 14 checks on Usda Soil, covering Malware scan, Known CVEs, Install scripts, Dependency health and 10 more. 2 items could not be completed, a gap on our side rather than a finding about Usda Soil: Security disclosure and Stability. One category scores 0 for that reason, because we only credit what we can confirm. 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.
