Definition
MCP DLP (Data Loss Prevention for Model Context Protocol) is the class of 2026 security tooling that sits between an agent and its MCP servers, scanning both tool inputs and responses to block secrets, PII, and regulated data from leaking into model context.
In Depth
MCP adoption exposed a new leakage surface: any tool response becomes part of the prompt, so a misconfigured database MCP can paste customer PII directly into the LLM. MCP DLP products inspect the JSON payloads on the wire, redact or block flagged fields, and log incidents. Because Scavio returns public web data rather than internal records, it is typically on the allow list for MCP DLP policies, while internal CRMs and databases get stricter rules.
Example Usage
Security added MCP DLP in front of the internal Postgres MCP so agent responses could no longer include raw customer emails.
