Common questions

Is US Government Data safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: APIFY_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.7) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

gov-data-mcp

123 US government open-data tools, as one MCP server.

EPA, FEMA, USGS, NOAA, FAA, USACE, FDIC, HUD, NRCS, HRSA, CMS, county assessor rolls and state licensing boards — all reachable as agent-callable tools, all reading directly from official government APIs and bulk files. No scraping, no HTML parsing, no rate-limit roulette.

mcp-name: io.github.malonestar/gov-data-mcp

npx gov-data-mcp

Install

You need a free Apify API token from console.apify.com/settings/integrations. Apify's free tier includes monthly platform credit that covers evaluating every tool here.

Claude Desktop / Claude Code / Cursor

"mcpServers": { "gov-data": { "command": "npx", "args": ["-y", "gov-data-mcp"], "env": { "APIFY_TOKEN": "apify_api_..." } } } }

Claude Desktop reads claude_desktop_config.json; Claude Code reads .mcp.json in your project; Cursor reads .cursor/mcp.json. The block is identical in all three.

What you get

12 dedicated tools for the highest-traffic questions, callable directly:

Tool	Answers
`site-due-diligence-bundle`	20-layer go / caution / no-go verdict for one coordinate
`epa-contaminated-site-screener`	Phase I ESA database search at ASTM E1527-21 distances
`faa-drone-airspace-checker`	Part 107 LAANC and airspace verdicts, batched
`hifld-grid-proximity-screener`	Nearest transmission line, substation, serving utility, ISO/RTO
`interconnection-queue-tracker`	Generator interconnection queues across 7 ISOs
`fdic-ncua-health-rollup`	Bank and credit-union health with real peer cohorts
`fema-nri-county-risk-profile`	County and census-tract natural-hazard risk
`fws-wetlands-proximity-screener`	NWI wetlands within a radius, with decode columns
`nhd-surface-water-404-screener`	Clean Water Act §404 surface-water screen
`epa-drinking-water-quality-screener`	SDWA violations, lead, PFAS occurrence
`parcel-owner-lookup`	Assessor-roll owner of record for an address
`license-verifier`	19 professional licensing boards across 9 states + OIG exclusions

Plus three tools that reach the other 111:

search-gov-data-tools — find a tool by keyword, agency or topic
describe-gov-data-tool — full input schema for any tool in the catalog
run-gov-data-tool — run any tool in the catalog

The catalog is bundled, so discovery costs nothing. Ask your agent *"what government data tools do you have for flood risk?"* and it will search all 123.

Vertical presets

The full server is the right default for a general-purpose agent. For an agent that serves one kind of buyer, a preset narrows the whole surface — the named tools *and* what search-gov-data-tools / describe-gov-data-tool / run-gov-data-tool can reach — to one shelf, and announces itself to the client under its own server name and description. Same package, same catalog, same release; nothing to install separately. Pass --preset or set GOV_DATA_MCP_PRESET. An unknown preset name refuses to start rather than guessing. npx gov-data-mcp --list-presets prints the current list as JSON.

Preset	Server name	Tools	For
`phase1-esa`	`gov-data-mcp-phase1-esa`	11 + 3 meta	Phase I ESA — Environmental Due Diligence
`cre-leads`	`gov-data-mcp-cre-leads`	12 + 3 meta	CRE & Local Business Leads — Who Just Changed State
`compliance`	`gov-data-mcp-compliance`	12 + 3 meta	KYB, Sanctions & Financial Compliance Screening

`phase1-esa` — Phase I ESA — Environmental Due Diligence

US government environmental records for Phase I Environmental Site Assessments and property due diligence: EPA Superfund / RCRA / UST / brownfield records at ASTM E1527-21 search distances, state tank and spill registries, historic land use from FRS SIC/NAICS, USGS historical topographic map coverage, NWI wetlands, Clean Water Act §404 surface water, RCRA corrective-action cleanups, orphaned wells, FEMA hazard risk and NFIP flood-loss history, plus a twenty-layer go / caution / no-go site verdict. Every tool reads the official source directly and reports what it could not check as null, never as clear.

11 tools: site-due-diligence-bundle · epa-contaminated-site-screener · historic-land-use-sic-contaminant-screener · state-tank-spill-registry-screener · usgs-historical-topo-records-review · epa-rcra-corrective-action-cleanup-monitor · orphaned-well-proximity-screener · fws-wetlands-proximity-screener · nhd-surface-water-404-screener · fema-nri-county-risk-profile · nfip-flood-loss-risk-screener — plus search-gov-data-tools, describe-gov-data-tool, run-gov-data-tool, scoped to this list.

Claude Desktop (claude_desktop_config.json), Claude Code (.mcp.json) and Cursor (.cursor/mcp.json) all take the same block:

"mcpServers": { "gov-data-phase1-esa": { "command": "npx", "args": ["-y", "gov-data-mcp", "--preset", "phase1-esa"], "env": { "APIFY_TOKEN": "apify_api_..." } } } }

Or, with the environment variable instead of the flag: "args": ["-y", "gov-data-mcp"] and "env": { "APIFY_TOKEN": "apify_api_...", "GOV_DATA_MCP_PRESET": "phase1-esa" }.

Command line: npx gov-data-mcp --preset phase1-esa

`cre-leads` — CRE & Local Business Leads — Who Just Changed State

Lead-generation feeds built from official state and county registers: new and pending liquor licenses, verified new business openings from Secretary of State and tax rosters, WARN layoff notices, newly licensed real estate agents, licensed childcare providers with contacts, parcel owner of record, absentee-owner lists, distressed-property signal stacks, NYC deed transfers and landlord registries, city business licenses and professional license verification. Delta modes return only what changed since the last run, so a scheduled agent pays for new leads, not the same roster twice.

12 tools: liquor-license-new-openings-tracker · sos-registry-monitor · warn-layoff-aggregator · realtor-license-roster-delta · childcare-provider-leads · parcel-owner-lookup · absentee-owner-lead-list-builder · distressed-property-signal-stacker · acris-deed-transfer-intel · nyc-landlord-registry-lead-list · city-business-license-leads · license-verifier — plus search-gov-data-tools, describe-gov-data-tool, run-gov-data-tool, scoped to this list.

Claude Desktop (claude_desktop_config.json), Claude Code (.mcp.json) and Cursor (.cursor/mcp.json) all take the same block:

Or, with the environment variable instead of the flag: "args": ["-y", "gov-data-mcp"] and "env": { "APIFY_TOKEN": "apify_api_...", "GOV_DATA_MCP_PRESET": "cre-leads" }.

Command line: npx gov-data-mcp --preset cre-leads

`compliance` — KYB, Sanctions & Financial Compliance Screening

Know-your-business and compliance screening from primary US government registers: company existence across Secretary of State registries, the Trade.gov Consolidated Screening List (OFAC SDN, BIS, State) as a delta, the DHS UFLPA Entity List, state Medicaid and HHS-OIG exclusion lists, professional license verification, GLEIF LEI ownership graphs, FDIC / NCUA institution health, FDIC structure changes, SEC investment-adviser registrations, PCAOB auditor engagements and SEC Regulation CF / A+ offering lifecycles. A screen that could not reach its source fails loudly rather than returning a clean sheet.

12 tools: kyb-company-verifier · consolidated-screening-list-delta · uflpa-entity-list-monitor · medicaid-exclusion-screener · license-verifier · gleif-ownership-graph · fdic-ncua-health-rollup · fdic-structure-change-delta-monitor · ria-registration-delta-monitor · pcaob-auditor-engagement-monitor · reg-cf-lifecycle-monitor · reg-a-plus-lifecycle-monitor — plus search-gov-data-tools, describe-gov-data-tool, run-gov-data-tool, scoped to this list.

Claude Desktop (claude_desktop_config.json), Claude Code (.mcp.json) and Cursor (.cursor/mcp.json) all take the same block:

"mcpServers": { "gov-data-compliance": { "command": "npx", "args": ["-y", "gov-data-mcp", "--preset", "compliance"], "env": { "APIFY_TOKEN": "apify_api_..." } } } }

Or, with the environment variable instead of the flag: "args": ["-y", "gov-data-mcp"] and "env": { "APIFY_TOKEN": "apify_api_...", "GOV_DATA_MCP_PRESET": "compliance" }.

Command line: npx gov-data-mcp --preset compliance

Example prompts

Screen 1200 Broadway, Denver CO for environmental risk under ASTM E1527-21 and tell me which findings fall inside the standard's search distance.

I'm siting a 40 MW solar project at 41.88, -93.10. Check grid proximity, prime farmland, wetlands, critical habitat and the interconnection queue, then tell me what would kill the project.

Can I fly a Part 107 mission at these six coordinates, and which ones need a DroneZone authorization rather than LAANC?

Which Texas banks show the 2006 CRE-concentration guidance flagged on both prongs?

How it works

Each tool is a published Apify Actor that this server invokes through the Apify API. The server starts the run, waits for a terminal state, and returns the rows.

Billing is to your own Apify account at each actor's published pay-per-result rate, listed on its Store page. Free-tier credit covers evaluation. A run that fails bills nothing beyond a fractional actor-start charge.

Every result carries the run_id and a `console.a
