This is a privacy proxy that sits between your MCP client and any upstream server, tokenizing PII before it reaches the model. Instead of pointing your agent at your Salesforce or internal API directly, you route through Stealth's URL and it intercepts tool results, replaces entities like names, emails, and SSNs with typed tokens, then passes the sanitized response to the LLM. It's zero storage by design, meaning Stratalize never persists your data, just generates deterministic tokens on the fly. Every call is ML-DSA-65 signed and anchored on Base for audit trails. Compliance profiles like HIPAA and GLBA are built in. You'd reach for this when you need to run agents over sensitive data but can't afford raw PII hitting third-party inference endpoints.
