Optimized for Anthropic Claude 5.5 Sonnet & Claude Haiku • SOC2 Type II Aligned

Supercharge Developers with Claude 5.5 Sonnet —
Without Exposing Proprietary Code or Secrets.

The zero-trust developer proxy for modern software teams. MaskCode parses Abstract Syntax Trees locally, strips live API keys, internal credentials, and customer PII, sends anonymized context to Anthropic Claude models, and re-hydrates patches seamlessly in your IDE.

How MaskCode & Anthropic Claude 5.5 Sonnet Work Together

Unlike naive regex blockers that destroy code syntax, MaskCode uses high-speed Tree-Sitter AST parsers to understand programming language semantics.

01

1. Local AST Tokenization

Runs natively inside developer IDEs via WebAssembly. Tree-Sitter creates an Abstract Syntax Tree (AST), differentiating variable names, API credentials, SQL strings, and proprietary algorithms from language syntax.

  • • 100+ Secret & PII Heuristic Rules
  • • Sub-2ms Tree-Sitter Parsing
  • • Preserves Type Signatures & Context
02

2. Claude 5.5 Sonnet API Dispatch

The sanitized prompt is sent to Anthropic's Claude 5.5 Sonnet API with enterprise zero-retention headers (X-Anthropic-Data-Retention: zero). Claude's world-class reasoning is applied without seeing raw secrets.

  • • 200k Context Window Support
  • • Prompt Caching Compatible
  • • 18% Lower Token Consumption
03

3. Local Deterministic Rehydration

When Claude returns refactored code, vulnerability patches, or test suites, MaskCode resolves the synthetic tokens back to original secrets locally on the developer's machine. Zero server memory is stored.

  • • Instant IDE Diff & Patch
  • • Cryptographic Token Salt Rotation
  • • Audit Log Export for CISO Review

Enterprise Security Pillars

Engineered for CISO Sign-Off & Developer Velocity

Everything your legal, compliance, and engineering teams require to approve Claude 5.5 deployment across thousands of developers.

Zero Data Retention

Strict protocol enforcement ensures that prompts sent to Claude are never used for model re-training or cached beyond the immediate request lifecycle.

AST Syntax Preservation

Unlike blunt regex masking that invalidates syntax trees, MaskCode retains exact scope, AST hierarchy, and type parameters so Claude understands your intent.

18-28% Token Compression

Deterministic token hashing collapses bloated repetitious variable names and enterprise boilerplate into compact semantic tokens, reducing API compute bills.

Cryptographic Audit Logs

Every masking operation produces a tamper-proof SHA-256 receipt for your compliance officers, certifying that zero credentials crossed perimeter boundaries.

Universal IDE & CI/CD Hooks

Ready-to-use plugins for VS Code, Cursor, JetBrains IntelliJ/PyCharm, and GitHub Actions pull request automated security synthesis.

Cloudflare Edge & On-Prem

Deploy as a local developer binary, an internal Docker container, or an ultra-low latency Cloudflare Worker proxy at edge points nearest your engineers.
