show_preflight_report
Read-only pre-show check: bridge reachability, node errors, topology, cook-time budget, GPU/display topology and perform-mode status in one PASS/UNVERIFIED/WARN/FAIL report. Use before rehearsals or venue handoff to see what is safe, unverified, suspicious, or failing without mutating the project.

What show_preflight_report does on tdmcp — TouchDesigner MCP server
AI agents call show_preflight_report to retrieve information from tdmcp — TouchDesigner MCP server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why show_preflight_report is rated Low
This tool retrieves and analyzes project state (bridge reachability, node errors, GPU/display topology, perform-mode status) and generates a report but explicitly does not modify the project. It is a diagnostic/query operation with no write, execute, or destructive side effects. Severity is low because misuse would only expose information about the project state, not cause harm.
From the tool's definition Tool name contains 'read-only' and 'pre-show check'; description emphasizes 'without mutating the project' and reports status on reachability, errors, topology, and cook-time budget — all diagnostic/observational operations with no side effects.
Attacks that exploit this kind of access
The rule that runs show_preflight_report 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 show_preflight_report, this is the rule to start with:
show_preflight_report is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect tdmcp — TouchDesigner MCP server, apply this rule, and every show_preflight_report call is checked against it from then on.
Questions about show_preflight_report
Read-only pre-show check: bridge reachability, node errors, topology, cook-time budget, GPU/display topology and perform-mode status in one PASS/UNVERIFIED/WARN/FAIL report. Use before rehearsals or venue handoff to see what is safe, unverified, suspicious, or failing without mutating the project. It is categorised as a Read tool in the tdmcp — TouchDesigner MCP server MCP Server, which means it retrieves data without modifying state.
Register the tdmcp — TouchDesigner MCP server MCP server in PolicyLayer and add a rule for show_preflight_report: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches tdmcp — TouchDesigner MCP server. Nothing to install.
show_preflight_report is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the show_preflight_report rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for show_preflight_report. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
show_preflight_report is provided by the tdmcp — TouchDesigner MCP server MCP server (@dpantani/tdmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
