The most dangerous Memvid tools

17 of Memvid's 40 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

How to control Memvid

PolicyLayer is an MCP gateway — it sits between your AI agents and Memvid, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations
{
  "memvid_delete": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations
{
  "memvid_api_fetch": {
    "limits": [
      {
        "counter": "memvid_api_fetch_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "memvid_ask": {
    "limits": [
      {
        "counter": "memvid_ask_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

  1. Create a free account and register Memvid — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about Memvid

Can an AI agent delete data through the Memvid MCP server? +

Yes. The Memvid server exposes 1 destructive tools including memvid_delete. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Memvid? +

The Memvid server has 11 write tools including memvid_api_fetch, memvid_binding, memvid_correct. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Memvid.

How many tools does the Memvid MCP server expose? +

40 tools across 4 categories: Destructive, Execute, Read, Write. 23 are read-only. 17 can modify, create, or delete data.

How do I enforce a policy on Memvid? +

Register the Memvid MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Memvid tool call.

Deterministic rules across all 40 Memvid tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
