Create a new color palette or load a preset palette (pico8, db16, db32, nes, gameboy, cga, endesga32, sweetie16)
AI agents use create_palette to create or update resources in Piskel MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Piskel MCP Server environment.
This tool creates or modifies color palette data, which is a write operation. It is reversible (palettes can be deleted, modified, or recreated) and has no destructive, executable, or financial implications. The blast radius is minimal—a misconfigured palette affects only the visual appearance of the artwork, not system integrity or other critical assets.
From the tool's definition Tool creates a new color palette or loads a preset palette. The description indicates it generates or modifies palette data (create, load), which are reversible write operations. 'Create a new color palette' directly indicates data creation.
Documented attack patterns abuse exactly the kind of access create_palette gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Piskel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_palette:
{
"version": "1",
"default": "deny",
"tools": {
"create_palette": {
"limits": [
{
"counter": "create_palette_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_palette 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.

Create a new color palette or load a preset palette (pico8, db16, db32, nes, gameboy, cga, endesga32, sweetie16). It is categorised as a Write tool in the Piskel MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Piskel MCP Server MCP server in PolicyLayer and add a rule for create_palette: 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 Piskel MCP Server. Nothing to install.
create_palette 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 create_palette 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 create_palette. 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.
create_palette is provided by the Piskel MCP Server MCP server (yafeiaa/piskel-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Piskel MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
