generate_asset
Generate an asset for a video of the iDos Games video studio and get it in the studio's asset format: voxel-character (a voxel hero — CharacterSpec recipe), rig2d-character (a 2D hero — rig recipe), image-actor (any creature or object that acts — picture cut-out), prop (an object in a hand), back...

What generate_asset does on iDos Games
AI agents use generate_asset to create or update resources in iDos Games, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your iDos Games environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
kind | string | Yes | voxel-character | rig2d-character | image-actor | prop | background | music. |
slot | string | — | Where the asset goes in the package: cast[<i>], set or music (optional; other slots only add the asset). |
tier | string | — | Quality/price tier of the image/music/text model (optional, see list_ai_tiers). |
style | string | — | Style family of the video, e.g. voxel-warm or chibi-2d (default voxel-warm). The heroes keep their own style. |
title | string | — | Name of the asset in the studio (optional, ≤ 60 characters). |
prompt | string | Yes | What to make, in English, precise (≤ 400 characters) — e.g. the plan item's generate.prompt. |
package | object | — | The video package ({ spec, assets }) from plan_video or an earlier generate_asset (optional). |
base_set | string | — | background only: the library scene (ref, kind set) whose stage and camera it reuses (default — the first scene of the style). |
title_id | string | — | Which game this is for — a label for the report, optional (credits are the publisher's). |
generation_id | string | — | Finish an asset whose generation was still running (optional; no new charge). |

Why generate_asset is rated Medium
An AI agent can call generate_asset faster than any human can review: one bad instruction and it creates or modifies resources in iDos Games by the hundred, each call as confident as the last.

The rule that runs generate_asset safely
PolicyLayer is an MCP gateway: it sits between your AI agents and iDos Games, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For generate_asset, this is the rule to start with:
generate_asset stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect iDos Games, apply this rule, and every generate_asset call is checked against it from then on.
Questions about generate_asset
Generate an asset for a video of the iDos Games video studio and get it in the studio's asset format: voxel-character (a voxel hero — CharacterSpec recipe), rig2d-character (a 2D hero — rig recipe), image-actor (any creature or object that acts — picture cut-out), prop (an object in a hand), background (a new scene: the picture goes into a library scene with its anchors and camera shots), music (a loop). Pass the video package from plan_video and the plan item's slot (cast[0], set, music…): the asset joins package.assets, takes that slot and the answer carries the updated package and its link. Prompts, model settings and the style lock are the studio's own. Costs one generation of the publisher's credits — text for the heroes, image or music for the rest (estimate_media_cost). If it is not ready in about two minutes, call generate_asset again with the same kind and generation_id. Check the hero recipes with validate_asset of @idosgames/mcp before publishing. It is categorised as a Write tool in the iDos Games MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
generate_asset accepts 10 parameters: kind, slot, tier, style, title, prompt, package, base_set, title_id, generation_id. Required: kind, prompt. The full parameter table on this page comes from the server's own tool schema.
Register the iDos Games MCP server in PolicyLayer and add a rule for generate_asset: 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 iDos Games. Nothing to install.
generate_asset 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 generate_asset 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 generate_asset. 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.
generate_asset is provided by the iDos Games MCP server (https://site.idosgames.com/api/v2/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
