Integration

Defastra integration

Defastra is a fraud-prevention and data-enrichment API that scores how risky an email address or a phone number is. Run a deep email check (risk level and 0 to 100 score, deliverability, domain age and disposability, data breaches, online profiles registered with the address) or a deep phone check (risk score, carrier and line type, location, live OS, online profiles). Every successful check debits the pay-as-you-go wallet of the Defastra account; a failed request is never debited. Results can contain personal data about the person behind the email or phone. Authentication is an API key from the Defastra dashboard (API page), sent in the X-API-KEY header.

Say what should happen.
The workflow builds itself.

When this happens, do that in Defastra.Built from the 2 Defastra tools below, on the connection you add once.

What you can do with Defastra

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Email, 1 operation

deep_email_checkDeep email checkPOSTScores the fraud risk of an email address (risk_level, risk_score 0-100) with deliverability, domain, data breach and online profile details. Billed: each successful check debits the Defastra wallet.

Phone, 1 operation

deep_phone_checkDeep phone checkPOSTScores the fraud risk of a phone number (risk_level, risk_score 0-100) with carrier, line type, location, live OS and online profile details. Billed: each successful check debits the Defastra wallet.

Use Defastra from Claude Code, Cursor or Codex

Connect Defastra in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Defastra operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

The workflow builds itself in front of you and picks the endpoints it needs. Drag the steps yourself on the canvas whenever you would rather be explicit.
