Your Question

Can the MCP host be your own website, or must it be what is currently implemented (Claude desktop, IDEs, etc)?

[tadasant]

You can implement your own MCP client (which can be within your own website if you so desire): https://modelcontextprotocol.io/quickstart/client

Many existing apps (hosts) that implement MCP clients are open source, so you can use them as reference examples: https://modelcontextprotocol.io/clients

Practically speaking, it's probably going to be difficult to implement an MCP client that interacts with servers only remotely (over SSE) today. Most of the MCP ecosystem is oriented around local clients/servers (stdio) right now. Fleshing out remote MCP support is a top priority for the team in H1 2025. After that, it'll be more practical to do something like what you're asking.
