## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## relayshield-mcp

`mcp-name: io.github.nzdsf2-gif/relayshield-mcp`

[RelayShield](https://relayshield.net) security intelligence as an MCP server — plug breach detection, SIM swap detection, domain lookalike monitoring, OAuth supply chain watchlist, and URL/file scanning directly into Claude and any MCP-compatible AI agent.

### Tools

| Tool | What it does | PAYG price |
|---|---|---|
| `check_breach` | Email breach lookup — 13 billion+ records via HIBP | $0.10 USDC |
| `check_sim_swap` | SIM swap / eSIM detection via live carrier data | $0.25 USDC |
| `check_domain_lookalikes` | Typosquat and lookalike domain detection with cert transparency | $0.50 USDC |
| `check_oauth_watchlist` | OAuth-app breach + stolen-token exposure via HIBP + stealer-log corpus | $0.30 USDC |
| `check_infostealer` | Infostealer malware log lookup via Hudson Rock Cavalier | $0.15 USDC |
| `scan_wallet` | EVM wallet on-chain risk check via GoPlus Security | $0.10 USDC |
| `scan_url` | URL malware/phishing scan across 70+ engines (async) | $0.05 USDC |
| `scan_file` | Binary malware scan across 70+ AV engines (async) | $0.10 USDC |
| `check_scan_result` | Poll for verdict after `scan_url` / `scan_file` | free |
| `check_mcp_registry_risk` | Typosquat/IOC/registration-age check for MCP servers | $0.35 USDC |
| `check_prompt_injection_breach` | Breach exposure sourced from AI-agent prompt-injection attacks | $0.35 USDC |
| `check_supply_chain` | Up to 10 vendor domains checked for breach/infostealer exposure | $0.10 USDC |
| `check_session_risk` | Active/reusable stolen session (cookie/token) exposure check | $0.30 USDC |
| `check_nhi_exposure` | Non-human-identity credential exposure — API keys, service tokens, PATs | $0.40 USDC |
| `check_secret_scan` | Secrets exposed in public GitHub repositories | $0.35 USDC |

`check_oauth_watchlist`, `check_supply_chain`, `check_session_risk`, `check_nhi_exposure`, and
`check_secret_scan` cover related ground — connected-app, session, and machine-credential exposure
for an identity or its supply chain — and are a natural set to use together when vetting an agent's
current authority, not just a login.

### Access modes

**Subscription** — API key from [api.relayshield.net/developers](https://api.relayshield.net/developers). All 15 tools available. Free tier: 100 calls/month. Paid tiers from $29/month.

**Pay-as-you-go** — No API key needed. Pay per check in USDC on Base (x402 protocol). Set `RELAYSHIELD_X_PAYMENT` with your payment proof. All 15 tools available ($0.05–$0.50/check, `check_scan_result` free). Call a tool with no payment set to receive pricing and payment instructions.

**Discovery** — Set neither key nor payment. Tool calls return payment requirements and a subscription link.

### Install

```bash
pip install relayshield-mcp
```

Or run without installing:

```bash
uvx relayshield-mcp
```

### Configure Claude Desktop

Edit `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\Claude\claude_desktop_config.json` (Windows):

**Subscription (RelayShield API key):**

```json
{
  "mcpServers": {
    "relayshield": {
      "command": "relayshield-mcp",
      "env": {
        "RELAYSHIELD_API_URL": "https://api.relayshield.net",
        "RELAYSHIELD_API_KEY": "your-relayshield-api-key-here"
      }
    }
  }
}
```

**Pay-as-you-go (x402 USDC on Base):**

```json
{
  "mcpServers": {
    "relayshield": {
      "command": "relayshield-mcp",
      "env": {
        "RELAYSHIELD_API_URL": "https://api.relayshield.net",
        "RELAYSHIELD_X_PAYMENT": "your-x402-payment-proof-here"
      }
    }
  }
}
```

Quit and relaunch Claude Desktop after editing.

### Configure Claude Code (CLI)

```bash
claude mcp add relayshield \
  --command relayshield-mcp \
  --env RELAYSHIELD_API_URL=https://api.relayshield.net \
  --env RELAYSHIELD_API_KEY=your-relayshield-api-key-here
```

### Usage examples

Once configured, ask Claude:

```
Check whether user@example.com has been breached.
```

```
Has there been a SIM swap on +14155551234?
```

```
Check acme.com for lookalike domains.
```

```
Are any OAuth apps connected to user@example.com in a recent breach?
```

```
Scan this URL for malware: https://suspicious-link.example.com
```

For URL and file scans, Claude automatically polls `check_scan_result` every 5 seconds until the verdict is ready.

### Environment variables

| Variable | Description |
|---|---|
| `RELAYSHIELD_API_URL` | API Gateway base URL (required) |
| `RELAYSHIELD_API_KEY` | RelayShield subscription key (subscription mode) — get one at [api.relayshield.net/developers](https://api.relayshield.net/developers) |
| `RELAYSHIELD_X_PAYMENT` | x402 payment proof — USDC on Base (pay-as-you-go mode) |

Set `RELAYSHIELD_API_KEY` **or** `RELAYSHIELD_X_PAYMENT` — not both. API key takes priority if both are set.

# 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.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("relayshieldadmin/relayshield-security-tools").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
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);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("relayshieldadmin/relayshield-security-tools").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call relayshieldadmin/relayshield-security-tools --silent --output-dataset

```

## MCP server setup

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

```

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).
