TLA-RS

What it does

tla-rs is a high-performance TLA+ model checker written in Rust that allows developers and engineers to verify the correctness of their system specifications. It explores all reachable states to check invariants and report counterexamples, serving as a lightweight, Rust-based alternative to the official TLC model checker.

Tools

• verify_spec: Checks a TLA+ specification for invariant violations and reports counterexamples.
• explore_states: Interactively explores the state space of a model to understand complex behaviors.
• analyze_properties: Performs property-satisfaction analytics and parameter sweeps on specifications.
• export_graph: Generates state graphs in DOT format for visual analysis of system transitions.

Installation

Add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "tla-rs": {
      "command": "tla-mcp",
      "args": []
    }
  }
}

Supported hosts
