Lean Proof Auto FAQs

Question 1

What is Lean Proof Auto?

Accepted Answer

Lean Proof Auto is a Model Context Protocol (MCP) server designed for Lean 4. It automates deterministic probing, comprehensive analysis, rigorous validation, and insightful context extraction for Lean 4 proof automation workflows.

Question 2

Which Lean 4 proof tactics does Lean Proof Auto support?

Accepted Answer

Lean Proof Auto specifically integrates with and supports automation probing and searching for popular Lean 4 tactics such as `aesop` and `grind`. It also facilitates general Lean validation (`verify`) for any proof attempt.

Question 3

How does Lean Proof Auto help streamline Lean 4 proof development?

Accepted Answer

Lean Proof Auto streamlines development by enabling rapid discovery and triage of theorems, measuring baseline automation coverage, searching for candidate automation scripts, validating proof attempts efficiently, and extracting crucial proof context, thereby accelerating the proof engineering process.

Question 4

What are the core features of Lean Proof Auto?

Accepted Answer

Its core features include static and deep analysis for Lean 4 files and theorems, objective-based ranking of theorem targets, single and batch automation probing for Aesop and Grind tactics, hint-set search for automated proofs, and robust validation of proof attempts.

Question 5

What are the prerequisites for running Lean Proof Auto?

Accepted Answer

To run Lean Proof Auto, you need Python `>=3.10` and `uv` for dependency management. Additionally, a Lean 4 project and toolchain are required for executing runtime tools like `verify`, `probe`, and `search_automated_proof`.
