Detailed Description

dlopen-loaded in-process MCP server plugin (gh#133).

Owns one plugin .so: the dlopen handle, the resolved C entry points from entropic/interfaces/i_mcp_server.h, and the server instance created through them. Destruction destroys the instance and closes the library, in that order.

Why this is not an MCPServerBase subclass

MCPServerBase::list_tools() and ::execute() are non-virtual — they iterate the server's own ToolRegistry — so an adapter deriving from it could not intercept them, and ServerManager would see an empty registry instead of the plugin's tools. Making them virtual would change the MCPServerBase vtable, which i_mcp_server.h defines as requiring a plugin-API version bump, and would break any consumer already subclassing the exported base.

Instead this mirrors the established ExternalMCPClient pattern: external servers are likewise not MCPServerBase subclasses but a parallel map with their own branch in ServerManager::route_tool_call. Plugins are the third such peer.
