claude mcp add --transport http \
  --header "X-Timezone: America/New_York" \
  time-server https://oss-mcp-time.onrender.com/mcp

Replace America/New_York with your IANA timezone.

Why?

Claude Code /cowork (remote) sessions run on Anthropic's infrastructure, not your machine. Local MCP servers like mcp-server-time aren't accessible. This hosted server solves that.

Self-Hosting

git clone https://github.com/YOUR_USERNAME/oss-mcp-time.git
cd oss-mcp-time
npm install
npm run build
npm start
