工具清单
工具（10）
🟢search(query)
Search TapWaterMap for US cities by name. Returns matching cities with an id you can pass to `fetch`. (ChatGPT/Deep-Research compatible.)
输入模式
{
"type": "object",
"properties": {
"query": {
"type": "string",
"description": "City name or partial name, e.g. 'Burlington'."
}
},
"required": [
"query"
],
"additionalProperties": false
}🟢fetch(id)
Fetch the full plain-English EPA tap-water record for a city id (e.g. 'vt/burlington') returned by `search`. (ChatGPT/Deep-Research compatible.)
输入模式
{
"type": "object",
"properties": {
"id": {
"type": "string",
"description": "City id like 'vt/burlington' (state/slug)."
}
},
"required": [
"id"
],
"additionalProperties": false
}🟢search_cities(query, state, limit)
Find covered US cities by name, optionally within a state. Returns counts + the page URL for each.
输入模式
{
"type": "object",
"properties": {
"query": {
"type": "string"
},
"state": {
"type": "string",
"description": "Optional 2-letter state code, e.g. 'TX'."
},
"limit": {
"type": "integer"
}
},
"required": [
"query"
],
"additionalProperties": false
}🟢get_city_water(city, state)
The core tool: what the EPA has on record for a city's tap water — the active community water systems serving it, populations, sources, and violations (contaminant, health-based or not, dates, status, level vs limit when recorded). Plain-English, sourced, never a safety verdict.
输入模式
{
"type": "object",
"properties": {
"city": {
"type": "string"
},
"state": {
"type": "string",
"description": "2-letter state code, e.g. 'VT'."
}
},
"required": [
"city",
"state"
],
"additionalProperties": false
}🟢get_water_system(pwsid)
EPA record for a single water system by its PWSID (e.g. 'VT0005053'): name, population served, source, and violations.
输入模式
{
"type": "object",
"properties": {
"pwsid": {
"type": "string"
}
},
"required": [
"pwsid"
],
"additionalProperties": false
}🟢list_state_cities(state)
List all covered cities in a state (with violation counts).
输入模式

"type": "object",
"properties": {
"state": {
"type": "string",
"description": "2-letter state code."
}
},
"required": [
"state"
],
"additionalProperties": false
}🟢find_cities(state, contaminant, healthBasedOnly, minPopulation, openViolationsOnly, ...)
Filter/rank cities across the dataset — e.g. cities in TX with open health-based violations, or cities with a specific contaminant. Returns ranked matches.
输入模式
{
"type": "object",
"properties": {
"state": {
"type": "string",
"description": "Optional 2-letter state code."
},
"contaminant": {
"type": "string",
"description": "Optional EPA contaminant code or name (use explain_contaminant to find a code)."
},
"healthBasedOnly": {
"type": "boolean"
},
"minPopulation": {
"type": "integer"
},
"openViolationsOnly": {
"type": "boolean",
"description": "Only cities with violations not returned to compliance."
},
"limit": {
"type": "integer"
}
},
"additionalProperties": false
}🟢compare_cities(cities)
Compare the EPA records of several cities side by side. Pass cities as 'City, ST' strings.
输入模式
{

"type": "array",
"items": {
"type": "string"
},
"description": "e.g. ['Burlington, VT', 'Houston, TX']"
}
},
"required": [
"cities"
],
"additionalProperties": false
}🟢explain_contaminant(contaminant)
Plain-English explanation of an EPA contaminant by name or code: the EPA name, whether the EPA classifies it as health-based, and how often it appears in our records. Not medical advice.
输入模式
{
"type": "object",
"properties": {
"contaminant": {
"type": "string",
"description": "Contaminant name or EPA code, e.g. 'TTHM' or '2950'."
}
},
"required": [
"contaminant"
],
"additionalProperties": false
}🟢coverage_stats
What TapWaterMap covers: states, cities, total EPA violation records, and the data quarter/date.
输入模式
{
"type": "object",
"properties": {},
