Your Idea

It would be nice if I could somehow differentiate what MCP tools/prompts/resources are linked to what MCP-endpoint within a single host.

Imagine I host an ASP.NET Core host at my.domain.com.

From the same host, I can have two MCP endpoints running:

my.domain.com/public/sse => publicly available MCP server, public tools for the external world, customers
my.domain.om/internal/sse => internal tools, in-house specific for employees (setup with auth, for example an API-key or similar).

app.Map("/public", p => p.UseMCP("public-mcp").AllowAnon();
app.Map("/internal", intern => intern.UseMCP("internal-mcp").RequireAuth();

Workarounds:

• Create 2 independent hosts and run them on different ports in the same .NET app (not all hosting providers support multiple ports, for example Heroku only supports port 80).
• Create 2 .NET apps, double spend on hosting.
