Best MCP Gateways for AI Coworker Agents 2026

Model Context Protocol gateways are presented as an increasingly important layer for deploying long-running AI coworker agents securely, providing centralized authentication, tool access controls, monitoring, audit trails, and policy enforcement as agents interact with enterprise data and employees. The comparison distinguishes MCP Gateways, which govern connections to tools and data, from Agent Gateways, which additionally manage persistent agent identities, permissions, memory, and monitoring. MintMCP is positioned as a managed enterprise platform combining both functions through SSO, SCIM-based RBAC, tool-level policies, hosted connectors, per-agent machine-to-machine credentials, and compliance features, while alternatives address different priorities: Bifrost, Docker, Obot, MCPX, and IBM ContextForge emphasize open-source or self-hosted control; TrueFoundry, Kong, and Portkey integrate MCP capabilities with broader LLM, API, or infrastructure platforms; and Composio focuses on rapid integration development for customer-facing AI applications. Key evaluation factors include least-privilege access, per-agent credentials, OAuth and SSO support, auditability, connector hosting, deployment model, operational overhead, and the ability to assess and restrict third-party tools before production use.
