agentgateway alternatives: 7 managed MCP and agent gateways (2026)

As enterprises rapidly deploy AI agents and Model Context Protocol tools, governance has become a central concern involving tool access, credentials, agent identities, policies, auditability, compliance, and operational ownership. Solo.io’s open-source, Rust-based agentgateway supports MCP, A2A, LLM, HTTP, and gRPC traffic with standalone and Kubernetes deployment, but requires customers to operate infrastructure and manage their own compliance responsibilities. The comparison examines seven alternatives spanning managed SaaS, full AI platforms, security-focused control planes, and self-hosted open-source gateways: MintMCP emphasizes managed MCP and agent governance, per-agent identities, virtual MCP endpoints, hosted connectors, runtime guardrails, monitoring, and SOC 2 Type II and HIPAA-related capabilities; Composio focuses on broad developer-oriented integrations; TrueFoundry combines gateway functions with a wider ML platform; Runlayer emphasizes shadow AI discovery and security scanning; Portkey, now part of Palo Alto Networks’ Prisma AIRS direction, focuses on LLM observability and cost optimization; Bifrost prioritizes low-overhead open-source performance; and Obot provides open-source and managed control-plane options. Organizations are advised to assess deployment requirements, identity and access controls, guardrails, integration breadth, audit logging, compliance documentation, pricing, portability, and the total operational burden of managed, self-hosted, VPC, Kubernetes, or air-gapped implementations.
