Meta's Model API rejects tool schemas nested deeper than 10 levels and fails the whole request instead of the offending tool, so one deep MCP tool (the Vercel MCP server publishes twelve) breaks every request for Muse Spark, both on the `meta` provider and through the opencode gateways. Drop the members that would nest past the limit for Meta/Muse models. Every other keyword stays on the node, so a lowered tool keeps its shape and stays callable instead of failing the request.
