Barndoor AI Gateway

Commercial

Agentic AI Security

Barndoor is an AI gateway that sits between an organization's AI clients, agents, and applications and the models and MCP servers they use. Every AI request is authenticated, checked against access and data loss prevention policies, metered against token/spend budgets, scrubbed of sensitive data, and logged before being passed through to a model or MCP server. The platform provides a dashboard showing user and agent activity, policy enforcement, and spend, along with detailed audit logs for tracing AI actions. It supports fine-grained access control down to the individual tool and action level, with each agent given its own profile, and enforces policies in real time. Cost controls allow organizations to view and cap AI spend by user, team, and model, and route requests automatically to more cost-effective options. Teams can access a catalog of 100+ MCP servers and models distributed through virtual keys, enabling governed delegation of work to AI. Barndoor works with any model provider and any MCP server, including custom or official MCP servers, and connects to identity providers and SIEM platforms. The company states the product is SOC 2 Type II compliant with zero-trust access controls.</description> <parameter name="summary">AI gateway that governs, monitors, and controls access, cost, and data loss for AI and agent traffic
