la_decode · Logic Analyzer MCP: Risk & Policy

WHAT IT DOES

What la_decode does on Logic Analyzer

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

la_decode Rate-limited

la_decode 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.
