AI agents use archive_cliche 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 archive_cliche 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.

Find the most surprising archive colour for a concept and generate a memorable one-liner subverting the obvious expectation. Supply a concept (e.g. 'love', 'grief', 'luxury', 'power') and optionally the expected colour (e.g. 'red' for love). The archive finds the contradiction and Claude writes the one-liner, short story, and tweet. Example: love + red returns Shakespeare's dark green with 'Love is not red. It is the green of someone still waiting in a field.' Use this for public-facing demos, content, and brand storytelling.. 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 archive_cliche: 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.
archive_cliche 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 archive_cliche 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 archive_cliche. 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.
archive_cliche 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.
