AI agents call get_midi_status to retrieve information from Midi without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool merely queries and returns the current state of MIDI connections. It has no side effects, does not send MIDI messages, and does not modify any system state. It is a pure information retrieval operation, falling clearly into the Read category with low severity since misuse would only expose connection status information.
From the tool's definition Tool name 'get_midi_status' and description 'Return current MIDI connection status' indicate a query operation that retrieves status information without modifying or sending any MIDI commands.
Attacks that exploit this kind of access
Return current MIDI connection status. It is categorised as a Read tool in the Midi MCP Server, which means it retrieves data without modifying state.
Register the Midi MCP server in PolicyLayer and add a rule for get_midi_status: 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 Midi. Nothing to install.
get_midi_status 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 get_midi_status 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 get_midi_status. 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.
get_midi_status is provided by the Midi MCP server (pnilan/midi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
