What clear-memory does on Vercel Ai Docs

AI agents call clear-memory to permanently remove resources in Vercel Ai Docs — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

Critical Risk

Why clear-memory needs a policy

Clearing memory is a destructive, irreversible operation. There is no indication that cleared conversation history can be recovered. The blast radius is medium because it affects only in-memory session data (not persistent documents), but clearing 'all sessions' could disrupt multiple users simultaneously.

From the tool's definition 'Clears the conversation memory' — the word 'clears' implies irreversible deletion of stored session data, affecting 'a specific session or all sessions'

Documented attack patterns abuse exactly the kind of access clear-memory gives an agent:

How to control clear-memory

PolicyLayer is an MCP gateway — it sits between your AI agents and Vercel Ai Docs, and nothing reaches the server without passing your rules. This is the rule we recommend for clear-memory:

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "clear-memory"
  ]
}

clear-memory disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

  1. Create a free account and register Vercel Ai Docs — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on clear-memory? +

Register the Vercel Ai Docs MCP server in PolicyLayer and add a rule for clear-memory: 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 Vercel Ai Docs. Nothing to install.

What risk level is clear-memory? +

clear-memory is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit clear-memory? +

Yes. Add a rate_limit block to the clear-memory 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.

How do I block clear-memory completely? +

Set action: deny in the PolicyLayer policy for clear-memory. 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.

What MCP server provides clear-memory? +

clear-memory is provided by the Vercel Ai Docs MCP server (ivanamador/vercel-ai-docs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
