Questions
What is the security-gate-x402 MCP server?
The Zero-Trust Safety & Settlement Rail for Autonomous AI Agents. Sub-10ms deterministic guardrails, key leak defense, and cryptographic Proof-of-Safety attestations via x402 on Base ($0.002).
What tools does security-gate-x402 expose?
3 in total: 3 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is security-gate-x402 safe to connect to an agent?
No — not without reading the findings first. The audit graded it F (27/100) and found 8 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does security-gate-x402 need?
It reads ADMIN_SECRET_KEY, AGENT_API_KEY, AGENT_PRIVATE_KEY, AGENT_VAULT_KEY, AGENT_WALLET_PRIVATE_KEY, ALLOW_DEV_BYPASS, DEPLOYER_PRIVATE_KEY, ENFORCE_PROD_KEYS, GATE_PRIVATE_KEY, GATE_SIGNER_PRIVATE_KEY, PRIVATE_KEY and SERVER_PRIVATE_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How current is this page?
The grade is for one exact copy of the source (066f353463c4), read on 2026-10-11. The repository is watched and re-audited when it changes.
