Higress Open-Source Remote MCP Server Hosting Solution with Upcoming MCP Marketplace

The Model Context Protocol (MCP) Server faces significant challenges in authentication, authorization, service reliability, and observability. Recent announcements from OpenAI and Anthropic, including Anthropic's new MCP version with a Streamable HTTP transport, are accelerating the protocol’s adoption as an emerging industry standard.

Local vs. Remote MCP Server

Local MCP Servers run on a user’s device and communicate with APIs via stdin/stdout. While simple, they suffer from environment dependencies, security risks (exposing credentials on each device), consistency problems across users, and high maintenance overhead.

Remote MCP Servers are cloud‑deployed, accessed via HTTP, and provide centralized security controls, unified permission management, and simplified deployment, enabling non‑technical users to access MCP capabilities through web or mobile clients.

Higress Remote MCP Server Hosting Solution

Higress, an AI‑native API gateway built on Envoy, offers a complete open‑source hosting solution for Remote MCP Servers. Its layered architecture supplies AI agents (e.g., Claude, Cursor) with MCP access while handling session management, OAuth2 authentication, audit logging, rate limiting, and routing.

The solution supports three integration modes: (1) an embedded Wasm‑based MCP Server inside Higress for SaaS API ecosystems, (2) transparent forwarding to external MCP services, and (3) dynamic discovery of external MCP servers via a service registry such as Nacos.

API‑Gateway Capabilities Aligned with MCP

Higress inherits Envoy’s mature features—unified authentication/authorization via OAuth2, fine‑grained traffic control, full‑stack observability through Prometheus and OpenTelemetry, and comprehensive audit logs—directly matching the security and observability requirements of MCP services.

Wasm‑Based MCP Server Extensions

Developers can write MCP Server logic in Go (or other languages), compile it to WebAssembly, and load it into Higress without restarting the gateway. Each Wasm plugin runs in an isolated sandbox, ensuring crashes do not affect the gateway, and can be updated dynamically while traffic continues.

Protocol Unloading and Multi‑Version Support

Higress can host both MCP protocol versions 20241105 and 20250326, handling POST+SSE, Streamable HTTP, and future WebSocket transports. This abstracts protocol details from downstream tools, allowing seamless upgrades as the MCP specification evolves.

Deployment and Operations Advantages

Deployed on Kubernetes, Higress leverages automatic scaling, gray releases, and Helm charts for one‑click installation. The platform can sustain hundreds of thousands of tool‑invocation requests per second with millisecond‑level latency, meeting enterprise performance expectations.

Open MCP Marketplace

Higress plans to launch a public MCP Marketplace on higress.ai (mid‑April 2025). The marketplace will offer a curated ecosystem of MCP Servers for scenarios such as document processing, data analysis, and code assistance, with one‑click provisioning via a web UI. An enterprise‑grade SaaS version will provide 99.99% SLA, compliance certifications, and 24/7 expert support.
