gov-data-mcp

# gov-data-mcp

**120 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`

```bash
npx gov-data-mcp
```

## Install

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

### Claude Desktop / Claude Code / Cursor

```json
{
  "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 108:**

- `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 120.

## 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](https://apify.com/malonestar) 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.apify.com` URL, so any claim an agent makes from this server can be traced back to the exact run that produced it.

### No Apify account? Agents can pay per run with x402

Every tool in this catalog is eligible for Apify's [agentic payments](https://docs.apify.com/integrations/x402): an agent with a funded [Coinbase Agentic Wallet](https://docs.cdp.coinbase.com/agentic-wallet/welcome) (USDC on Base, $1 minimum) buys a prepaid Apify token over the x402 protocol and uses it as `APIFY_TOKEN` — no account, no billing setup, no API key. The ready-made skill is [apify.it/x402-awal](https://apify.com/apify.it/x402-awal):

```bash
npx -y awal auth login <email>            # one-time wallet auth
npx awal x402 pay 'https://agi.apify.com/protocols/x402/prepaid-tokens?amount=5&currency=usd' --max-amount 5000000 --json
# → returns a bearer token; export it as APIFY_TOKEN and start this server as usual
```

The prepaid balance is an absolute spending cap and expires after 14 days. Every tool here charges only per result — none pass platform usage through, none require full permissions, and none run in Standby mode, which are the three things that make an Actor ineligible. Prices are in the catalog (`usdPer1000Results` on every search hit), so an agent can see the cost before spending.

## On honest answers

These actors are built around one rule: **a failure must never be presentable as "nothing was found."** That distinction matters most in exactly the cases people use this for — telling a buyer a property is clear of contamination, telling a pilot an airspace is uncontrolled, telling a lender a borrower is unlicensed.

So this server:

- reports `run_status` on every call, and never attaches a `rows` key to a run that did not succeed
- distinguishes *"the run SUCCEEDED and the source genuinely matched nothing"* from *"the run failed"* in the response text, explicitly
- retries transient Apify 429/5xx, then fails loudly saying the platform failed and no conclusion should be drawn about the government source
- treats an unknown tool name as a catalog miss, never as an empty result

The underlying actors carry the same discipline: per-source status on every row, `null` meaning *not checked* rather than *checked and negative*, live drift assertions that fail the run when an upstream silently truncates, and pagination guards on sources that answer HTTP 200 with a partial payload. Each actor's Store page documents the specific traps it defends against.

## Coverage

**120 tools**, every one reading an official US government API or bulk file. The MCP server exposes 15 of them directly — twelve named tools plus `search-gov-data-tools`, `describe-gov-data-tool` and `run-gov-data-tool`, which reach the rest — because agents choose badly when handed more than about twenty tools.

Each entry links to its full input/output schema, pricing and worked examples.
