WHAT IT DOES

What log_performance does on tdmcp — TouchDesigner MCP server

AI agents use log_performance 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 log_performance is rated Medium

The tool reads network snapshot data and optionally captures a preview image, but its primary side effect is writing a persistent markdown journal entry and binary thumbnail to the vault filesystem. While it also reads data, the most severe action is the Write (file creation). It is not Destructive (no deletion), not Execute (no code execution), and not Financial.

From the tool's definition WRITE a dated journal entry to Performances/<date>-<title>.md in the vault (the thumbnail is saved as a binary attachment)

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs log_performance safely

PolicyLayer is an MCP gateway: it sits between your AI agents and tdmcp — TouchDesigner MCP server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For log_performance, this is the rule to start with:

log_performance Rate-limited

log_performance stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
