Axiomatic Prover — MCP Server

Lean 4 MCP server: compile and prove theorems with Mathlib.

Connect

Add to your MCP client (e.g. Claude Desktop claude_desktop_config.json):

{
  "mcpServers": {
    "ax-prover": {
      "type": "streamable-http",
      "url": "https://prover.axiomatic-ai.com/mcp/"
    }
  }
}

Authentication uses OAuth 2.1 via GitHub — your MCP client handles the flow automatically.

Tools

Submit (async — returns a job_id)

ToolDescription
lean4_buildCompile Lean 4 source code in a Mathlib-enabled sandbox. Code is sent to external cloud services for compilation; if proving, also for AI processing.
lean4_prove_theoremsAutomatically prove Lean 4 theorems that contain sorry. Code is sent to external cloud services for compilation and AI proving.

Poll

ToolDescription
lean4_get_job_statusPoll for the status and result of any ax-prover job.

All submit tools are asynchronous — they return a job_id immediately. Poll with lean4_get_job_status(job_id) until status is completed or failed.
