The description mentions "credential".

description: "Scan up to 2,048 characters for common credential patterns and return only masked matches..."
```


## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `fabler_list_products`

- The name "fabler_list_products" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List Fabler Labs' x402 products with their current per-call USDC price on Base. Free, no wallet or payment required. Note: this MCP endpoint (Streamable HTTP, mounted directly on the store at /mcp) exposes this catalog plus a free bounded secret-scan preview. The paid tools (full secret scanning, agent-config audit, OG card rendering) are not yet wired for payment over MCP — call them directly over HTTP with x402 (GET /openapi.json describes every priced route), or use the wallet-capable stdio MCP server from GitHub for automatic payment: npx -y github:fablerlabs/x402-tools.
```

### `fabler_scan_secrets_preview`

- The name "fabler_scan_secrets_preview" says "preview": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Scan up to 2,048 characters for common credential patterns and return only masked matches. Free, no wallet or account required. For larger inputs, use the $0.005 full scanner through the wallet-capable client: npx -y github:fablerlabs/x402-tools.
```
