## Pricing

Pay per event + usage

This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Public Data MCP: Recalls, Gov Contracts, ZIP Income, Leads

MCP server for AI agents (Claude, ChatGPT, Cursor, n8n). 7 tools over official US public data: product & vehicle recalls, federal contract winners, IRS income by ZIP, new Texas businesses, domain WHOIS/DNS/email intel and website tech stacks. Pay per tool call.

### Connect

**Server URL:** `https://intuitive-ytterbium--public-data-mcp.apify.actor/mcp`
Send your Apify API token as `Authorization: Bearer <APIFY_TOKEN>`.

Claude Desktop / Cursor / any Streamable-HTTP MCP client:

```json
{"mcpServers": {"public-data": {"url": "https://intuitive-ytterbium--public-data-mcp.apify.actor/mcp",
  "headers": {"Authorization": "Bearer YOUR_APIFY_TOKEN"}}}}
```

You can also add it through Apify's own MCP gateway at mcp.apify.com.

### How to use

**Example use cases**

1. **AI assistants (Claude, ChatGPT, Cursor):** ask about recalls, federal contracts or ZIP income in plain English.
2. **Sales agents & n8n workflows:** enrich prospect domains and find new Texas businesses from inside an agent.
3. **Research copilots:** pull official US public data with sources instead of guessing.

**Steps:** add the server URL above to your MCP client with your Apify token, then ask a question. Example tool call:

```json
{"tool": "domain_lookup", "arguments": {"domains": ["apify.com", "stripe.com"]}}
```

**Sample output** (from a real run of the underlying lookup, trimmed):

```json

### Batch / scheduled use

Each tool also exists as a regular Actor by the same author (Recall Brand Watch, Gov Contract Competitor Intel, IRS SOI ZIP Income, Texas New Business Leads, Bulk Domain Intel, Website Tech Stack Detector) for big batches and schedules.

### Notes

Official public sources only: saferproducts.gov, openFDA, USDA FSIS (best effort), NHTSA, USAspending.gov, IRS SOI, Texas Comptroller open data, RDAP/DNS. No personal data beyond what businesses publish. Not legal or financial advice.

#### FAQ

**Do I need to run a batch Actor first?** No. This is a standby MCP server. Point your client at the Server URL with your Apify token and call tools directly.

**Certificate / hostname errors?** Use the hyphenated hostname `intuitive-ytterbium--public-data-mcp.apify.actor` (hyphen in the username segment). An underscore there fails TLS.

**Free trial?** A free Apify account includes monthly free platform credit. Tool events are $0.01–$0.03 and only successful calls are charged.

**Prefer Apify's MCP gateway?** You can also add this Actor through [mcp.apify.com](https://mcp.apify.com) (OAuth; no token pasted into the client config).

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);

## CLI example

```bash
echo '{}' |
apify call intuitive_ytterbium/public-data-mcp --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,intuitive_ytterbium/public-data-mcp"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
