Perplexity

Command-Line Password Hashing

The `bcrypt_hash` tool lets Claude Code generate secure password hashes directly from your terminal. SREs and DevOps engineers can feed raw passwords to the CLI, getting back high-security hashes with custom salt rounds up to 12. This eliminates the need to install local scripting runtimes or crypto packages on minimal server environments. Claude Code runs the MCP Server in a headless environment, making it perfect for automated user provisioning.

Headless Password Verification via Claude Code

The `bcrypt_verify` tool lets Claude Code validate passwords against stored hashes inside shell scripts. Your agent passes the credentials to the tool, receiving a boolean match result without exposing sensitive data in terminal history. This headless verification ensures your automation pipelines can test database access securely. By delegating validation to the MCP server, Claude Code replaces flaky custom shell scripts with a standard, timing-attack-resistant verification mechanism.

Secure CI/CD Database Seeding via MCP Server

The `bcrypt_hash` tool lets Claude Code generate mock user databases for automated staging environments. During pipeline runs, Claude Code generates secure hashes for test accounts on the fly. This ensures your staging databases are fully secure from the start. Your agent can run headless integration tests with production-grade security without manually managing seed scripts.

Setup guide

Set up Bcrypt Hash Engine MCP in Claude Code

Prerequisites

Claude Code CLI installed (npm install -g @anthropic-ai/claude-code)
Active Vinkius subscription with a valid endpoint token

1

Run the add command

Open your terminal and run the command shown on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com. Use --scope user to make it available across all projects.
2

Verify the connection

Start a Claude Code session and type /mcp to list connected servers. You should see bcrypt-hash-engine-mcp with a green status indicator.
3

Start using tools

Ask Claude Code something like "Check my latest Bcrypt Hash Engine transactions." It will automatically discover and invoke the available Bcrypt Hash Engine tools.

Common questions about Bcrypt Hash Engine MCP in Claude Code

Run `claude mcp add --transport http bcrypt-hash-engine -- ` in your terminal. This command registers the server in your `~/.claude.json` configuration file for headless execution.

Yes, Claude Code can invoke the server programmatically during automated pipeline runs. This lets you hash and verify passwords in headless environments without manual intervention.

Local openssl commands do not natively support the bcrypt format with configurable salt rounds easily. This MCP Server provides a direct, standard-compliant interface for Claude Code without complex shell parsing.

Claude Code supports stdio, http, and sse transports. You can configure the server connection details directly in your global user configuration file.

Yes, all cryptographic operations run within a secure, isolated V8 sandbox that isolates your plaintext passwords and hashes. No data is cached or written to persistent storage, keeping your credentials safe from terminal snooping.
