Delete a previously stored memory by key. Use when context is stale, the task is done, or you want to clear sensitive data the agent saved earlier. Pair with remember and recall.
AI agents call forget to permanently remove resources in Mcp Color Pizza — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

key | string | Yes | Memory key to delete |
Parameters from the server's own tool schema.
This tool irreversibly removes stored data (memory/state) that cannot be recovered after deletion. Although the blast radius is limited to the agent's own stored memories rather than external systems, deletion operations fall under the Destructive category per the hierarchy, and the ability to erase agent context or sensitive data without undo constitutes a medium-severity risk if misused by a compromised agent.
From the tool's definition Tool description explicitly states 'Delete a previously stored memory by key' and mentions clearing data. The verb 'Delete' and the irreversible nature of removing stored memories indicate destructive capability.

Delete a previously stored memory by key. Use when context is stale, the task is done, or you want to clear sensitive data the agent saved earlier. Pair with remember and recall. It is categorised as a Destructive tool in the Mcp Color Pizza MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
forget accepts 1 parameter: key. Required: key. The full parameter table on this page comes from the server's own tool schema.
Register the Mcp Color Pizza MCP server in PolicyLayer and add a rule for forget: 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 Mcp Color Pizza. Nothing to install.
forget is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the forget 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 forget. 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.
forget is provided by the Mcp Color Pizza MCP server (https://gateway.pipeworx.io/color-pizza/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
