- Homepage: https://github.com/GoPlausible/algorand-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "mnemonic_to_secret_key",
    "arguments": {}
  }
}
```

## Why mnemonic_to_secret_key is rated Low

This tool converts a mnemonic phrase into a cryptographic secret key. While it is technically a read/derivation operation with no side effects, misuse is catastrophic: exposing a secret key gives full control over a blockchain wallet, enabling fund theft, transaction signing, and irreversible financial loss. The severity is critical due to the blast radius if an AI agent leaks or mishandles the derived secret key.

From the tool's own definition: "Convert a mnemonic to a secret key"

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Algorand MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "mnemonic_to_secret_key": {}
  }
}
```
