SEVLEX GATEWAY CORE PRODUCT•LAYER 7 ZERO-TRUST

The Zero-Trust Security Fabric for Coding Agents

A high-performance reverse proxy and governance gateway purpose-built for the Model Context Protocol (MCP). Transparently inspects, filters, and logs every tool execution with sub-0.1ms wire overhead.

How Sevlex Intercepts the MCP Protocol Wire

Transparently sits between AI runtime processes (Claude Desktop, Cursor, Windsurf) and downstream MCP servers over stdio or SSE.

ToolGuard™ Parameter Deep Packet Inspection

Real-Time AST Validation & Sanitization

Rather than treating JSON-RPC payloads as opaque blobs, ToolGuard parses the internal syntax tree of commands in-flight. It blocks destructive database DDL (DROP TABLE, TRUNCATE), prevents catastrophic bash mutations (rm -rf /), and blocks path traversal attempts (../../.aws/credentials).
