Output Formats

Formats

mcp time get-current-time 'America/New_York'            # human-readable (default)
mcp time get-current-time 'America/New_York' -o json     # JSON for scripts
mcp time get-current-time 'America/New_York' -o yaml     # YAML
mcp time get-current-time 'America/New_York' -o raw      # raw text, no formatting

Scripting

-o json is always script-safe:

  • Tool output goes to stdout
  • Diagnostics go to stderr
  • Exit codes are stable and meaningful
# Use with jq
mcp time get-current-time 'UTC' -o json | jq -r '.content[0].text'


# Use in a script
if mcp acme check-status -o raw; then
  echo "OK"
fi

Listing formats

The tools, resources, and prompts commands also support -o:

mcp time tools -o json     # full tool schemas as JSON
mcp time tools -o yaml     # YAML
mcp time tools -o raw      # just tool names, one per line

-o raw is useful for piping into other commands:

mcp time tools -o raw | xargs -I{} mcp time tools {}
