The most dangerous Agentvault tools

10 of Agentvault's 11 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

How to control Agentvault

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

Block financial tools by default
{
  "executeTrade": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Requires human approval."
      }
    ]
  }
}

Financial tools should be explicitly enabled per use case, not open by default.

Deny destructive operations
{
  "closeCreditBond": {
    "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
{
  "initReputation": {
    "limits": [
      {
        "counter": "initreputation_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "preCheck": {
    "limits": [
      {
        "counter": "precheck_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 Agentvault — 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 Agentvault

Can an AI agent move money through the Agentvault MCP server? +

Yes. The Agentvault server exposes 6 financial tools including executeTrade, listForSale, buySettlement. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.

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

Yes. The Agentvault server exposes 2 destructive tools including closeCreditBond, revert. 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 Agentvault? +

The Agentvault server has 1 write tools including initReputation. 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 Agentvault.

How many tools does the Agentvault MCP server expose? +

11 tools across 3 categories: Execute, Read, Write. 1 are read-only. 10 can modify, create, or delete data.

How do I enforce a policy on Agentvault? +

Register the Agentvault 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 Agentvault tool call.

Deterministic rules across all 11 Agentvault tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
