How to remove Warning: Please use the legacy build in Node.js environments. (since this console message inhibits MCP startup)

// if (isNodeJS) {
//   warn("Please use the `legacy` build in Node.js environments.");
// }

Exec locally

# start locally
$ deno run -A src/index.ts

# exec
$ {"jsonrpc":"2.0","id":"toolcall-1","method":"tools/call","params":{"name":"getUrlToMd","arguments":{"url":"https://code.visualstudio.com/docs/editing/intellisense"}}}

# ---
# start locally + exec + save result
$ echo '{"jsonrpc":"2.0","id":"toolcall-1","method":"tools/call","params":{"name":"getUrlToMd","arguments":{"url":"https://code.visualstudio.com/docs/editing/intellisense"}}}' | \
    deno run -A src/index.ts | \
    grep "result" | \
    jq -r '.result.content[0].text | fromjson' > example.md
