Best LLM Proxies for Enterprise Teams (2026)

Enterprise LLM proxies and MCP gateways centralize authentication, access controls, observability, rate limiting, cost management, and compliance functions that become difficult to manage when organizations use multiple AI models, clients, and autonomous agents. The comparison presents MintMCP as a governance-focused MCP and agent platform built around SSO, SCIM-based role controls, tool-level authorization, non-human agent identities, monitoring, and runtime security guardrails, while noting its integrations and SOC 2 Type II and HIPAA-related assurances. Other options address different priorities: Bifrost emphasizes high-performance open-source routing, LiteLLM offers broad provider compatibility, Portkey provides managed multi-model access and caching, Kong extends conventional API gateway infrastructure to AI and agent protocols, TrueFoundry combines gateway functions with broader AI infrastructure, Cloudflare offers edge-native controls, Helicone focuses on lightweight observability, OpenRouter simplifies access to many hosted models, and Zuplo unifies programmable API, AI, and MCP gateway capabilities. The text distinguishes LLM proxies, which govern traffic to model providers, from MCP gateways, which govern agents’ access to tools and enterprise data, and recommends evaluating identity management, audit logs, guardrails, deployment and data-residency needs, budget controls, and security certifications when selecting a platform.
