Wave Security Browser MCP Protection

Wave Security delivers robust in-browser protection for interactions with web agent tools. Key features include: • Granular control over tool registration and execution • Real-time inspection of tool call inputs and outputs • On-device data loss prevention (DLP) • Vendor-neutral, single browser extension deployment • Instant policy updates across all open tabs This platform acts as a browser-native firewall, specifically designed to secure the emerging WebMCP specification. It addresses the critical security gap created as web pages begin to function as agent tool servers, allowing agents to directly call tools for actions like booking travel or moving money. Traditional network and endpoint security measures often miss these client-side interactions. Wave Security provides two crucial control points: Tool Availability, where it can hide or deny tools based on name, metadata, or schema content before an agent sees them; and Call Protection, which inspects each call's inputs and outputs in real-time, allowing, warning, blocking, or limiting results before they return to the agent. This ensures sensitive data remains protected and malicious intent is thwarted. Built for security teams and IT administrators, Wave ensures compliance and data integrity when users interact with web agent tools. It provides comprehensive visibility and control over web agent tool usage, safeguarding organizational data and mitigating risks associated with browser-native tool calls. The firewall supports Chrome today and will extend to Edge, Safari, and Firefox as WebMCP expands.
