WHAT IT DOES

What export_externalized_tree does on tdmcp — TouchDesigner MCP server

AI agents use export_externalized_tree to create or update resources in tdmcp — TouchDesigner MCP server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your tdmcp — TouchDesigner MCP server environment.

RISK

Why export_externalized_tree is rated Medium

The tool creates/modifies externalized TouchDesigner component files (.tox format). This is a Write operation because it creates or modifies data reversibly — the exported files can be re-imported, edited, or reverted via version control (git-diffable format supports this). It does not delete data (so not Destructive), does not execute arbitrary code (Execute), and has no financial impact.

From the tool's definition Tool description states 'Save a COMP as a git-diffable externalized .tox tree' — 'save' indicates creating or modifying files in a persistent format (.tox files are TouchDesigner component files).
