Category Health and Science
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. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-water-quality-portal). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 6 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability61
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
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.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
wqp_get_results ~302
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 |
No output schema declared.
No examples provided.
wqp_list_characteristics ~168
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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" |
No output schema declared.
No examples provided.
wqp_results_near_point ~203
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | Decimal degrees, WGS84 |
| limit | number | – | Max results to return (default 100, max 1000) |
| longitude | number | yes | Decimal degrees, WGS84 (negative in the US) |
| startDate | string | – | Earliest sample date, YYYY-MM-DD |
| within_miles | number | – | Search radius in miles (default 10) |
No output schema declared.
No examples provided.
wqp_search_sites ~312
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).
| Name | Type | Req | Description |
|---|---|---|---|
| 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 |
