save_capture · Logic Analyzer AI MCP: Risk & Policy

WHAT IT DOES

What save_capture does on Logic Analyzer AI MCP

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

WHY IT NEEDS A POLICY

Why save_capture needs a policy

This tool most likely saves captured signal data to storage, making it a Write operation (reversible modification/creation of data). While it could theoretically be destructive if it overwrites existing captures without confirmation, the lack of descriptive information and the naming pattern of sibling export/analysis tools suggest standard save functionality.

From the tool's definition Tool name 'save_capture' combined with sibling tools that capture and analyze signals suggests persistent storage of captured data. The empty description limits certainty, but the name indicates writing/persisting capture data.

Verdict

save_capture Rate-limited

save_capture 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.
