goose session crashes after adding nostrbook

I have followed instructions to install MCP, but cannot get the workbook to function, see error below.

I get this error:

goose session

Failed to start extension: nostr, "Failed to start the MCP server from configuration Stdio(nostr: npx -y xjsr @nostrbook/mcp) Call to '' failed for 'initialize'. Error from mcp-server: Stdio process error: (node:24420) [DEP0060] DeprecationWarning: The util._extendAPI is deprecated.

I also tried the alternate command npx -y deno run -A jsr:@nostrbook/mcp:

uname -r 6.14.9-300.fc42.x86_64

vfox --version vfox version 0.6.10
