WHAT IT DOES

What decrypt_data does on Tenzro Ledger MCP

AI agents call decrypt_data to retrieve information from Tenzro Ledger MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why decrypt_data is rated Low

Decryption is fundamentally a read operation: it converts encrypted data to readable form without side effects or state changes. However, severity is elevated to 'medium' rather than 'low' because successful decryption of sensitive financial or identity data (implied by the server's wallet, payments, identity functions) could expose confidential information if decryption keys are compromised or an agent decrypts…

From the tool's definition Tool decrypts data via 'Decrypt AES-256-GCM encrypted data' but does not modify, delete, or execute code/commands—it only retrieves plaintext from ciphertext.

RECOMMENDED RULE

The rule that runs decrypt_data safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Tenzro Ledger MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For decrypt_data, this is the rule to start with:

decrypt_data Allowed

decrypt_data is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "decrypt_data": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Tenzro Ledger MCP, apply this rule, and every decrypt_data call is checked against it from then on.

FAQ

Questions about decrypt_data

What does the decrypt_data tool do? +

Decrypt AES-256-GCM encrypted data. Input must include nonce and tag. It is categorised as a Read tool in the Tenzro Ledger MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on decrypt_data? +

Register the Tenzro Ledger MCP server in PolicyLayer and add a rule for decrypt_data: 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 Tenzro Ledger MCP. Nothing to install.

What risk level is decrypt_data? +

decrypt_data is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit decrypt_data? +

Yes. Add a rate_limit block to the decrypt_data 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 decrypt_data completely? +

Set action: deny in the PolicyLayer policy for decrypt_data. 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 decrypt_data? +

decrypt_data is provided by the Tenzro Ledger MCP server (https://canton-mcp.tenzro.network/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
