AI agents use resolve_music to create or modify resources in Rootvine. 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 resolve_music repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Rootvine.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Returns ranked results covering streaming (Spotify, Apple Music, Tidal, YouTube Music), digital purchase (iTunes, Amazon MP3, Bandcamp), and physical media (vinyl, CD via Amazon, Discogs). Use when a user asks about music — whether they want to listen, own digitally, or find a collector edition. Ranked by trust × price × availability, never by commission.. It is categorised as a Write tool in the Rootvine MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Rootvine MCP server in PolicyLayer and add a rule for resolve_music: 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 Rootvine. Nothing to install.
resolve_music 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 resolve_music 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 resolve_music. 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.
resolve_music is provided by the Rootvine MCP server (rootvine-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
