Send a FM8 matrix modulation route. Routes connect a source (like LFO1, ENV1) to a destination (like PITCH, CUTOFF). Common sources: LFO1, LFO2, ENV1, ENV2, A, B, C, D. Common destinations: PITCH, CUTOFF, RESONANCE, A, B, C, D, E, F, X, Y, Z.
AI agents invoke send_fm8_route to trigger actions in FM8 MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool triggers an external operation — sending MIDI CC messages to control FM8 synthesizer parameters. It doesn't merely read or write data in a traditional sense; it actively sends control signals to an external hardware/software synthesizer, making it an Execute category action. Misuse could result in undesired sound changes or disruption of a live performance, warranting medium severity.
From the tool's definition Send a FM8 matrix modulation route. Routes connect a source (like LFO1, ENV1) to a destination (like PITCH, CUTOFF, RESONANCE).
Attacks that exploit this kind of access
Send a FM8 matrix modulation route. Routes connect a source (like LFO1, ENV1) to a destination (like PITCH, CUTOFF). Common sources: LFO1, LFO2, ENV1, ENV2, A, B, C, D. Common destinations: PITCH, CUTOFF, RESONANCE, A, B, C, D, E, F, X, Y, Z. It is categorised as a Execute tool in the FM8 MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the FM8 MCP Server MCP server in PolicyLayer and add a rule for send_fm8_route: 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 FM8 MCP Server. Nothing to install.
send_fm8_route is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the send_fm8_route 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 send_fm8_route. 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.
send_fm8_route is provided by the FM8 MCP Server MCP server (thesigma1receptor/fm8mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
