Blockbench MCP Overview

For content changes, load blockbench-use first. The running server's tool list and schemas determine available operations; this source skill can describe tools newer than an installed bundle. Tool status and success text are not a substitute for result inspection.

Discover the Host and Workflow

get_capabilities: include_tools=true
# → blockbench, plugin, project, format, formats, tools, notes
list_modes
# → current_mode, modes[{id, available, selected, ...}]

project may be null. Use exact registered format IDs: Generic Model is normally free. Inspect a prospective format with get_capabilities: format_id="free" without switching projects. Detailed feature flags can be null (unknown); compact listings distinguish true flags and unknown flags. Installed plugin formats are supported through discovery rather than a fixed whitelist in these skills.

When a tool depends on editor state, use list_modes and set_mode: mode_id="<returned ID>", then refresh availability. Animate uses animate, not animation. Changing mode does not change project format.
