Fabler x402 Tools tools 2
fabler_list_productsList 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_previewScan 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.
