Best Agent Gateways for Multi-Agent Workflows 2026

Enterprise adoption of multi-agent AI is accelerating, increasing demand for governance systems that can centralize authentication, permissions, tool access, session management, monitoring, and audit trails across agents that delegate tasks and access enterprise data. The material presents MintMCP Gateway as a combined MCP and agent-governance platform, emphasizing SCIM-based RBAC, per-agent identities, curated tool bundles, OAuth brokering, custom policy middleware, hosted connectors, memory governance, and local shadow-AI detection for tools such as Claude Code and Cursor. It also compares alternatives including TrueFoundry, Stacklok ToolHive, Bifrost, Tetrate, Portkey, Cloudflare, Kong, Obot, and Lunar.dev, which vary in their focus on LLM routing, Kubernetes isolation, low latency, distributed policy enforcement, LLMOps, edge deployment, API management, orchestration, and unified API governance. Across these products, key considerations include tool-level controls to prevent unapproved capability expansion, enterprise identity integration, observability across agent chains, deployment requirements, data locality, and compliance programs such as SOC 2 and HIPAA.
