❓ Frequently Asked Questions
Why is Aletheia 100% free and open-source?
Aletheia is released under Apache 2.0 / MIT as an open developer standard. It gives every autonomous AI coding agent a lightweight, zero-cost symbolic verification engine that catches infinite loops, arithmetic edge cases, and invalid ASTs locally before spending money on cloud compute.
How does Fuel Metering trap infinite loops in under 5 microseconds?
Instead of waiting for a 2-second timeout in a cloud container, Aletheia tracks symbolic evaluation steps in fast CPU registers. When an untrusted loop or recursive function exhausts its fuel budget, Aletheia instantly traps the execution in <5µs, returning an early failure verdict with zero cloud latency.
How does Aletheia integrate with AI coding agents like Cursor and Claude Desktop?
Aletheia provides a native Model Context Protocol (MCP) server. Agents can invoke aletheia_verify_ast to symbolically verify logic, simplify boolean invariants, and prove code safety before running execution tests.
What languages and AST formats does Aletheia support?
Aletheia supports Python, JavaScript/TypeScript, and Go AST parsing, symbolically simplifying boolean logic, proving loop termination, and checking boundary constraints.
Can Aletheia replace unit test frameworks?
Aletheia complements unit test frameworks by acting as a zero-latency pre-filter. It instantly eliminates trivial syntax errors, infinite loops, and arithmetic overflows before unit test suites or compilers are invoked.
Where can developers get the open-source code and MCP tools?
Full source code, CLI binaries, and MCP servers are available on GitHub and installable with zero configuration via npx @aletheia/mcp-server.
