Remix this and open main.ts to edit the MCP server and find its HTTP trigger endpoint.

Since the adapter only works with streamable HTTP on Val Town, you'll probably need mcp-remote to connect to it from clients that don't yet support this newer transport.

{
  "mcpServers": {
    "my-val": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "<YOUR-VAL-ENDPOINT>/mcp"
      ]
    }
  }
}

The MCP TypeScript SDK uses Node-specific APIs that don't play nicely with Deno or edge functions:

• https://github.com/modelcontextprotocol/typescript-sdk/pull/349
• https://github.com/modelcontextprotocol/typescript-sdk/issues/385

Vercel's MCP adapter translates the standard web Request that Val Town gives us into something the SDK can understand, and reduces overall boilerplate.
