AI agents call dsl_get_tempo_info to retrieve information from REAPER MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves temporal metadata (tempo, BPM, time signature) from a REAPER project without modifying any audio, settings, or state. It is a pure query operation with no blast radius if invoked inappropriately—returned data cannot harm the project or cause unintended actions.
From the tool's definition Tool name is 'dsl_get_tempo_info' and description states 'Check current speed and time signature.' The verb 'check' and 'get' indicate data retrieval with no modification or side effects.

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_get_tempo_info:
{
"version": "1",
"default": "deny",
"tools": {
"dsl_get_tempo_info": {}
}
}dsl_get_tempo_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check current speed and time signature. Use when users ask about tempo, BPM, or timing. It is categorised as a Read tool in the REAPER MCP Server MCP Server, which means it retrieves data without modifying state.
Register the REAPER MCP Server MCP server in PolicyLayer and add a rule for dsl_get_tempo_info: 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 REAPER MCP Server. Nothing to install.
dsl_get_tempo_info 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 dsl_get_tempo_info 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 dsl_get_tempo_info. 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.
dsl_get_tempo_info is provided by the REAPER MCP Server MCP server (shiehn/total-reaper-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
