AI agents use dsl_track_mute 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.
Muting a track is a reversible state change (can be unmuted), placing it in the Write category. Severity is low as it only affects audio playback state within a DAW session. Confidence is reduced due to empty description.
From the tool's definition Tool name 'dsl_track_mute' and empty description. Based on name alone, infers muting/unmuting a track in REAPER DAW.

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_track_mute:
{
"version": "1",
"default": "deny",
"tools": {
"dsl_track_mute": {
"limits": [
{
"counter": "dsl_track_mute_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}dsl_track_mute 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.
