Prover
Hook Lean 4 compile, prove, and Mathlib formalization into your agent loop while building verified math, crypto, or safety-critical logic.
Overview
Axiomatic Prover is a MCP server for the Build phase that runs Lean 4 compile, theorem proving, and Mathlib formalization via a streamable-http remote.
What is this MCP server?
- Lean 4 MCP server with compile, prove, and formalize workflows
- Mathlib-oriented formal mathematics support per publisher description
- Hosted streamable-http remote at prover.axiomatic-ai.com/mcp/
- Open-source base repo ax-prover-base-mcp on GitHub
- Version 0.1.0—early formal-methods integration for coding agents
- MCP server version 0.1.0
- Publisher describes compile, prove, and Mathlib formalization capabilities
What problem does it solve?
Formal verification in Lean 4 is painful to wire into chat-driven development, so agents cannot close proof obligations while you code.
Who is it for?
Solo builders and researchers using Lean 4 who want agent-side proving without standing up prover infrastructure first.
Skip if: Teams with no Lean background, quick CRUD apps with no correctness proofs, or offline-only workflows that cannot use HTTP MCP.
What do I get? / Deliverables
Your agent sends Lean goals to a hosted prover MCP and gets compile and proof feedback inside the same build session.
- Compile and proof feedback on Lean 4 code from agent sessions
- Formalization iterations grounded in Mathlib workflows
- Documented remote MCP endpoint for reproducible agent configs

Journey fit
Theorem proving and formalization are active construction of correct artifacts—not launch marketing or ops monitoring. A remote prover MCP extends your agent toolchain the same way linters or test runners do during implementation.
How it compares
Lean 4 proof-service MCP—not a general Python unit-test skill or informal code-review checklist.
Common Questions / FAQ
Who is Axiomatic Prover for?
Developers and researchers formalizing mathematics or software in Lean 4 who want MCP-accessible compile and prove assistance.
When should I use Axiomatic Prover?
During Build while writing specs, lemmas, or verified modules and you need iterative proof feedback from your agent.
How do I add Axiomatic Prover to my agent?
Register the streamable-http remote https://prover.axiomatic-ai.com/mcp/ in your MCP client and invoke tools with valid Lean 4 sources.
