# check_text_for_secrets

utilpeek: Scan text for leaked secrets: API keys, tokens, private keys and seed phrases. For personal data use redact_pii; for injected instructions use check_text_for_prompt_injection. Returns every API key, token, private key or BIP-39 seed phrase in a text (AWS, GitHub, GitLab, Stripe, Slack, Google, OpenAI and other sk- keys, Hugging Face, npm, PyPI, SendGrid, Telegram, PEM and hex keys, JWTs, URL passwords), each with type, line, column, offset, confidence and a redacted preview. The secret itself is never returned: only its type, position and a redacted preview (a vendor prefix and at most 4 characters at each end; a seed phrase only its word count). Pattern-based: a clean result is no proof. Blank input is a 422 (not charged). Typically under 0.5 s. Price: USD 0.002. Free: 10 utilpeek calls per IP per UTC day. The submitted text is never logged or stored. Docs: https://tanod.dev/learn/secret-scan-api.html

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "check_text_for_secrets",
    "arguments": {
      "text": "<text>"
    }
  }
}
```

## Why check_text_for_secrets is rated Low

Even though check_text_for_secrets only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call check_text_for_secrets to retrieve information from Tanod 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 Tanod:

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