Vulnify Overview

The Vulnify MCP server connects AI agents to Vulnify’s runtime authorization API before they read, write, delete, export, or send data. It provides tools for testing policies, recording decisions, retrieving outcomes, listing policies, and checking MCP tool calls. Use it when agent actions need policy enforcement and audit records; the authoritative result is the `finalDecision` value. Hosted access uses stateless Streamable HTTP with OAuth 2.1, while local execution uses Node.js 20 or newer and an API key.
