NeuralTrust vs. Arcade: MCP Gateway Comparison 2026

NeuralTrust TrustGate and Arcade are both open-source, self-hosted MCP gateways that connect agents to MCP servers and expose a catalog of tools through a single endpoint. While both platforms share core functionalities such as open-source access and self-hosting capabilities, TrustGate distinguishes itself by offering more comprehensive features that cater to enterprise needs without necessitating compromises. TrustGate not only matches Arcade on important developer features but also extends its functionalities by incorporating LLM traffic governance, native SIEM integrations, and real-time content inspection and enforcement on tool calls, providing a unified platform for managing agent estates with built-in security. In contrast, Arcade focuses primarily on tool authorization, offering OAuth-based user control over tool access without inspecting the content of the calls or providing native SIEM connectors. TrustGate's session memory enables it to analyze entire conversations, identifying patterns of abuse that span multiple calls, whereas Arcade evaluates access on a per-call basis. Ultimately, the choice between TrustGate and Arcade hinges on whether an organization prioritizes comprehensive security and management of the entire agent ecosystem or focuses solely on tool call authorization.
