relayshield-mcp

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

RelayShield 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

ToolWhat it doesPAYG price
check_breachEmail breach lookup — 13 billion+ records via HIBP$0.10 USDC
check_sim_swapSIM swap / eSIM detection via live carrier data$0.25 USDC

check_oauth_watchlistOAuth-app breach + stolen-token exposure via HIBP + stealer-log corpus$0.30 USDC
check_infostealerInfostealer malware log lookup via Hudson Rock Cavalier$0.15 USDC

check_scan_resultPoll for verdict after scan_url / scan_filefree
check_mcp_registry_riskTyposquat/IOC/registration-age check for MCP servers$0.35 USDC
check_prompt_injection_breachBreach exposure sourced from AI-agent prompt-injection attacks$0.35 USDC
check_supply_chainUp to 10 vendor domains checked for breach/infostealer exposure$0.10 USDC
check_session_riskActive/reusable stolen session (cookie/token) exposure check$0.30 USDC
check_nhi_exposureNon-human-identity credential exposure — API keys, service tokens, PATs$0.40 USDC
check_secret_scanSecrets 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. 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

pip install relayshield-mcp

Or run without installing:

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):

{
  "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):

{
  "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)

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

VariableDescription
RELAYSHIELD_API_URLAPI Gateway base URL (required)
RELAYSHIELD_API_KEYRelayShield subscription key (subscription mode) — get one at api.relayshield.net/developers
RELAYSHIELD_X_PAYMENTx402 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.
