New Components

MCP Proxy Consumer

The MCP Proxy Consumer is a new component that enables proxying MCP (Model Context Protocol) requests to upstream MCP servers. It allows ConnectPlaza to act as an intermediary in MCP-based integrations, transparently forwarding tool requests and responses between AI clients and backend MCP services. This makes it possible to chain or aggregate multiple MCP-capable services behind a single ConnectPlaza endpoint.

MCP Service Gateway

The MCP Service Gateway is a new component that exposes backend services over the MCP (Model Context Protocol) protocol. Using the MCP Service Gateway it becomes possible to make any backend service accessible as an MCP-compatible resource for AI clients, assistants, or chatbots. This complements the existing MCP Consumer and Listener components, completing the MCP integration story in ConnectPlaza.
