Describe a DeepMind parameter by name: NRPN address (when known), raw/normalized ranges, and enum labels (when available). For FX params, see resource deepmind12://references/deepmind_fx.
AI agents call describe_param to retrieve information from Patchwork Deepmind without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a lookup/query operation that retrieves parameter specifications and reference documentation. It does not modify synth settings, send MIDI, execute code, delete data, or commit financial transactions. The phrase 'Describe...by name' and reference to documentation lookup confirms it is purely informational.
From the tool's definition Tool name 'describe_param' and description 'Describe a DeepMind parameter' indicate data retrieval only. Returns informational metadata (NRPN address, ranges, enum labels) with no side effects or modifications to synth state.
Attacks that exploit this kind of access
Describe a DeepMind parameter by name: NRPN address (when known), raw/normalized ranges, and enum labels (when available). For FX params, see resource deepmind12://references/deepmind_fx. It is categorised as a Read tool in the Patchwork Deepmind MCP Server, which means it retrieves data without modifying state.
Register the Patchwork Deepmind MCP server in PolicyLayer and add a rule for describe_param: 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 Patchwork Deepmind. Nothing to install.
describe_param 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 describe_param 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 describe_param. 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.
describe_param is provided by the Patchwork Deepmind MCP server (truthanb/patchwork-deepmind). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
