Common questions

Is Bridgeguard MCP safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 2 months ago, and the latest version (1.0.0) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Quantum Shield

Post-quantum asset protection protocol for Ethereum using NIST-standardized cryptography

What is Quantum Shield?

Quantum Shield protects smart contract assets against quantum computing threats using NIST FIPS 204 (ML-DSA/Dilithium) and FIPS 205 (SLH-DSA/SPHINCS+) dual post-quantum signatures, combined with a decentralized Prover Pool, VRF-based selection, and time-locked custody.

Key Features
  • Dual PQC Signatures — ML-DSA-65 + SLH-DSA for defense-in-depth
  • Prover Pool — Decentralized verification with stake-weighted selection via VRF
  • Time-Locked Custody — 24h normal unlock, 7-day emergency path with bond
  • Observer Network — Independent challenge system with quadratic slashing
  • On-Chain Governance — veQS token voting, security council, insurance fund
  • 11 Sub-Applications — Consumer, Prover, Observer, Explorer, Enterprise, Governance, Admin
