Why Alethos?

Give your AI coding assistants the context they need to write better, more maintainable code.

Native MCP Integration

Works seamlessly with Claude Desktop, Cursor, and any other MCP-compatible client out of the box.

Instant Analysis

Calculates cyclomatic complexity in milliseconds, analyzing ASTs directly without executing code.

Multi-Language Support

Supports TypeScript, Python, Go, Rust, and more. If your AI can write it, Alethos can analyze it.

Quick Installation

Add Alethos to your Claude Desktop or Cursor MCP configuration.

Privacy First

Your source code stays yours. Alethos is designed so sensitive code never reaches the LLM.

No Code in Context

File uploads go directly to the analysis engine. Your source code never passes through the LLM context window.

Ephemeral Processing

Uploaded files are deleted immediately after analysis. Nothing is persisted to disk or logged beyond the session.

Results Only

The LLM receives only structured complexity metrics — function names, line counts, and scores. Never file content.
