Module MCP/MCPConnection

Description

Base MCP client — JSON-RPC 2.0 transport over stdio or HTTP gateway. Supports two transport modes:

• stdio: Spawns the EP MCP server binary as a child process (default)
• gateway: Connects to an MCP Gateway via HTTP (for agentic workflow environments)

Gateway mode is activated when EP_MCP_GATEWAY_URL env var is set or gatewayUrl is provided in options.
