Bcrypt Hash Engine MCP Connector for Claude

A+

Hash and verify passwords with the industry-standard bcrypt algorithm. Two tools in one: hash with configurable salt rounds, and verify against stored hashes. Pure JS — zero compilation.

An agent just generated a user registration flow. The password is stored in plaintext. That's not a bug — it's a security incident waiting to happen.

Bcrypt is the algorithm that Dropbox, GitHub, and every serious authentication system uses for password storage. It includes a built-in salt, is intentionally slow to resist brute-force, and this MCP provides it as pure JavaScript — no native compilation, no node-gyp headaches.

The Superpowers

  • Two Tools, One MCP: bcrypt_hash creates the hash, bcrypt_verify checks passwords against stored hashes.
  • Built-in Salt: Every hash includes a unique random salt — no manual salt management needed.
  • Configurable Cost: Salt rounds 4-16. Default 10 (~100ms). 12 for financial systems. 14+ for government.
  • Pure JavaScript: Uses bcryptjs — works in Edge, Lambda, Cloudflare Workers, and any Node.js runtime without compilation.

bcrypt_hash

Bcrypt is the industry standard for password hashing — it includes a salt and is intentionally slow to resist brute-force attacks. Salt rounds control the computational cost (10 is default, 12+ for high security). Never store plaintext passwords. Hashes a password using bcrypt with configurable salt rounds. Pure JS, no native compilation needed

bcrypt_verify

Pass the password and the hash, and receive a boolean isMatch result. This is the only correct way to verify bcrypt passwords — never compare hashes directly. Verifies a password against a bcrypt hash. Returns boolean match result

A new user just signed up. Hash their password 'MyS3cur3P@ss!' for secure storage in PostgreSQL.

Hash: $2a$10$N9qo8uLOickgx2ZMRZoMye... | 60 chars, salt embedded, ready for INSERT.

User is trying to log in. Check if their password matches the stored hash.

isMatch: true — password verified. Allow login.

Our compliance officer requires 12 salt rounds minimum. Re-hash this password with higher security.

Hash: $2a$12$... | 12 rounds, ~400ms computation time. Meets financial-grade requirements.

SHA-256 and MD5 are fast — that's the problem. An attacker can try billions of hashes per second. Bcrypt is intentionally slow (configurable via salt rounds), making brute-force attacks economically infeasible.
