The rapid rise of autonomous AI agents across enterprises is creating a new class of security and governance challenges that are not adequately addressed with today’s technology. Context Forge MCP Gateway is an open-source, security-focused middleware that provides fine-grained control and extensibility for agent operations. With over 2.6k GitHub stars and a rapidly growing user community, Context Forge addresses emerging threat classes including prompt injection, data leakage, and misuse of sensitive resources. At its core, Context Forge introduces a plugin architecture modeled after Linux Security Modules, embedding reusable security hooks at critical points in agent execution (e.g., prompt handling, tool invocation, data transformation). This modular foundation enables organizations to enforce contextual policies at scale—ranging from PII redaction and provenance tagging to prompt injection detection and policy-based access control. With 39 plugins already available, Context Forge is establishing a standards-aligned ecosystem for securing agent workflows in real-world enterprise deployments. By blending research-driven design with open-source adoption it creates a practical path for organizations to advance agent trustworthiness, safety, and compliance.
