Engineering — WriteGuard: Fine-grained controls for MCP Servers

WriteGuard: Fine-grained controls for MCP Servers

At Cloudflare, we knew we could not depend on every employee to configure every agent perfectly or watch every tool call. Before expanding write access across our own internal MCP servers, we built WriteGuard. We are now bringing those controls to Cloudflare MCP server portals through a private beta.
