Secure MCP with DLP Controls

The Problem

Giving an agent direct web access via MCP is a DLP disaster waiting to happen: agents can paste customer PII into third-party search endpoints, exfiltrate internal domains, or get prompt-injected into uploading private data. Most MCP servers ship zero guardrails.

The Scavio Solution

Scavio MCP ships DLP controls baked into the server: domain allowlists, query-content regex filters, and structured outbound logs. Configure ALLOWED_QUERY_PATTERNS and BLOCKED_TERMS via env vars; Scavio drops queries that match sensitive patterns before they leave your network.

Who It Is For

Security and platform teams deploying MCP-powered agents in regulated environments.

Key Benefits

• Pre-query DLP filter with regex and blocked-term list
• Structured audit log of every query (who, what, when)
• Domain allowlist for SERP results to stay in approved set
• SOC 2 Type II compliant hosting tier available
• Works with existing DLP tools via webhook

Python Example

# Env vars on the MCP process:
# SCAVIO_BLOCKED_TERMS=ssn,credit-card,private-key
# SCAVIO_ALLOWED_DOMAINS=*.wikipedia.org,*.docs.example.com

import os, requests
r = requests.post('https://api.scavio.dev/api/v1/search',
    headers={'x-api-key': os.environ['SCAVIO_API_KEY']},
    json={'query': 'hello'})
print(r.json())

JavaScript Example

// Env vars on the MCP process:
// SCAVIO_BLOCKED_TERMS=ssn,credit-card,private-key
// SCAVIO_ALLOWED_DOMAINS=*.wikipedia.org

const r = await fetch('https://api.scavio.dev/api/v1/search', {
  method: 'POST',
  headers: { 'x-api-key': process.env.SCAVIO_API_KEY, 'content-type': 'application/json' },
  body: JSON.stringify({ query: 'hello' })
});
console.log(await r.json());
