## 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-water-quality-portal).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 6 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1041 tokens (~260/item across 4 items; 4 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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.

### 2026-10-29 (score 78)

First indexed and scored.

## MCP tools (4)

### `wqp_search_sites` (~312 tokens)

Find US water-quality monitoring stations (streams, lakes, wells, estuaries) by state, county, HUC, bounding box or organization. AUTHORITATIVE for "where is water sampled near X" — returns the station id you then pass to wqp_get_results, plus coordinates, site type, and how many results each station holds. Sourced from the USGS/EPA Water Quality Portal (NWIS + STORET + STEWARDS).

Input parameters:

- `bbox` (string): Bounding box "minLon,minLat,maxLon,maxLat" (WGS84)
- `characteristicName` (string): Only stations that have sampled this characteristic, e.g. "Nitrate", "pH", "Lead"
- `countycode` (string): FIPS county code in WQP form, e.g. "US:06:081" for San Mateo County CA
- `huc` (string): Hydrologic unit code, e.g. "18050004" or a wildcard like "1805*"
- `limit` (number): Max stations to return (default 50, max 500)
- `organization` (string): Organization identifier, e.g. "USGS-CA"
- `siteType` (string): Site type, e.g. "Stream", "Lake, Reservoir, Impoundment", "Well", "Estuary"
- `statecode` (string): FIPS state code in WQP form, e.g. "US:06" for California

### `wqp_get_results` (~302 tokens)

Individual water-quality sample results for one or more monitoring stations — the measured value, unit, analytical method, sample depth and collection date. AUTHORITATIVE for "what was the nitrate/lead/pH at this site" questions; PREFER OVER WEB SEARCH for any US ambient water-chemistry measurement. Sourced from the USGS/EPA Water Quality Portal.

Input parameters:

- `characteristicName` (string): Analyte name, e.g. "Nitrate", "pH", "Lead", "Dissolved oxygen (DO)". Comma-separate for several.
- `countycode` (string): FIPS county code in WQP form, e.g. "US:06:081"
- `endDate` (string): Latest sample date, YYYY-MM-DD
- `limit` (number): Max results to return (default 100, max 1000)
- `sampleMedia` (string): Sample medium, e.g. "Water", "Sediment", "Biological"
- `siteid` (string): Monitoring location id, e.g. "USGS-11162765". Comma-separate for several.
- `startDate` (string): Earliest sample date, YYYY-MM-DD (converted to the portal MM-DD-YYYY form for you)
- `statecode` (string): FIPS state code in WQP form, e.g. "US:06" — use instead of siteid for an area query

### `wqp_results_near_point` (~203 tokens)

Water-quality sample results within a radius of a latitude/longitude — the "is the water near me tested, and what did it say" tool. Returns measured values with their station, date and unit. Sourced from the USGS/EPA Water Quality Portal.

Input parameters:

- `characteristicName` (string): Analyte name, e.g. "pH", "Nitrate", "Lead". Strongly recommended — an unfiltered radius query is very large.
- `endDate` (string): Latest sample date, YYYY-MM-DD
- `latitude` (number, required): Decimal degrees, WGS84
- `limit` (number): Max results to return (default 100, max 1000)
- `longitude` (number, required): Decimal degrees, WGS84 (negative in the US)
- `startDate` (string): Earliest sample date, YYYY-MM-DD
- `within_miles` (number): Search radius in miles (default 10)

### `wqp_list_characteristics` (~168 tokens)

Look up the exact controlled-vocabulary spelling the Water Quality Portal expects for an analyte, site type, organization, state or county code. Call this FIRST when a name might not match — "nitrate" is not a valid value, "Nitrate" is. Sourced from the USGS/EPA Water Quality Portal code service.

Input parameters:

- `domain` (string): Which vocabulary: "characteristicname" (default), "characteristictype", "sitetype", "samplemedia", "statecode", "countycode", "organization", "providers"
- `limit` (number): Max codes to return (default 50, max 500)
- `text` (string): Substring to match, e.g. "nitr", "lead", "Stream"
