AI agents use palette_heritage to create or modify resources in Colour Memory. 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 palette_heritage 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 Colour Memory.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access palette_heritage gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Given a legacy palette, generate an archive-grounded premium support system. For each existing colour: identifies its historical archive anchor, names it, and scores its provenance confidence. Detects palette gaps and fills them from the archive. Returns full palette with roles, confidence scores, CSS tokens, and production notes. Every addition has a named historical origin.. It is categorised as a Write tool in the Colour Memory MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Colour Memory MCP server in PolicyLayer and add a rule for palette_heritage: 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 Colour Memory. Nothing to install.
palette_heritage 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 palette_heritage 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 palette_heritage. 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.
palette_heritage is provided by the Colour Memory MCP server (https://colour-memory-api-production.up.railway.app/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
