AI agents use dsl_automate_section to create or update resources in REAPER MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your REAPER MCP Server environment.
This tool creates or modifies automation data—a core DAW feature that adjusts parameters over time. Automation changes are reversible (can be undone or modified), making this a Write operation rather than Execute. The severity is medium because misuse could alter a music project's mix significantly, but changes remain non-destructive and editable.

Documented attack patterns abuse exactly the kind of access dsl_automate_section gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and REAPER MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for dsl_automate_section:
{
"version": "1",
"default": "deny",
"tools": {
"dsl_automate_section": {
"limits": [
{
"counter": "dsl_automate_section_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}dsl_automate_section 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.
