Part of the Mcp Music Studio MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use play-live-pattern to create or modify resources in Mcp Music Studio. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call play-live-pattern repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mcp Music Studio.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Live-code music patterns using TidalCycles mini-notation in JavaScript. Layer drums, synths, and bass with stack(). Choose from 72 drum machine banks, 128 GM instruments, built-in synths, and a full effects chain. Patterns play in a REPL the user can edit directly. Use get-strudel-guide for genre templates, sound references, and advanced features like visualization, arrangement, and sample loading. The Strudel REPL renders inline with an editable code editor, visualizations, and playback controls.. It is categorised as a Write tool in the Mcp Music Studio MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for play-live-pattern. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mcp Music Studio MCP server.
play-live-pattern is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the play-live-pattern rule in your Intercept 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 Intercept policy for play-live-pattern. 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.
play-live-pattern is provided by the Mcp Music Studio MCP server (linxule/mcp-music-studio). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
