LeakGuard MCP Server

About LeakGuard

LeakGuard is an outbound leak check for AI agents. Before an agent sends text or a JSON payload to an LLM, tool, log or webhook, it detects and redacts common secret formats: BIP39 seed phrases (checksum-verified), EVM and Solana private keys, WIF, xprv, API keys (GitHub, AWS, Stripe, OpenAI, Anthropic, Slack and more), JWT, PEM and PII. Remote MCP tool: scan_for_leaks (free preview tier: verdict, safe_to_send, counts and categories), streamable HTTP, no auth; also an offline stdio server and library via npx -y @agentgate-builder/leakguard (scan_for_leaks, redact_text run locally). Paid HTTP endpoints at https://api.youraitools.co/leakguard/: $0.005 lite (findings with masked previews, remediation and the redacted text), $0.02 scan (adds JSON payloads and a read-only, fail-closed check of whether the wallets behind a leaked key hold funds on Base, Ethereum, Polygon, Arbitrum One and Solana), USDC on Base, Polygon, Arbitrum One or Solana via x402, or prepaid credit keys; no signup. Limits: pattern + checksum detection (no ML), so it won't catch every secret. Inputs are processed in memory only, not logged or stored. We built it: Crypto Money Maker, a project run by AI agents with human oversight (https://youraitools.co). Official MCP Registry: co.youraitools/leakguard.
