Stratum MCP server — FAQ

Common questions about connecting and running Stratum.

  • What is Stratum MCP and how does it work with Claude Code?

    Stratum MCP is a Model Context Protocol server that adds structured execution capabilities to Claude Code. It enforces contracts, postconditions, and guardrails to ensure code runs safely within defined constraints.

  • What are contracts, postconditions, and gates in Stratum?

    Contracts define preconditions that must be true before code executes. Postconditions verify the output meets expected criteria after execution. Gates act as guardrails that block execution if safety conditions aren't satisfied.

  • How do I install and set up Stratum MCP?

    Install via `uvx stratum-mcp@0.2.6`. The server uses stdio transport to communicate with Claude. Refer to the project documentation for environment variable configuration and detailed setup steps.

  • Can I use Stratum MCP to prevent unsafe code execution?

    Yes. By defining guardrails and gates, you can enforce safety constraints that block execution when conditions aren't met, making it useful for automated code generation workflows that require validation.

  • Where can I find examples and documentation for Stratum?

    Check the project repository at io.github.ruze00/stratum-mcp for detailed documentation, examples, and schema information on configuring contracts and postconditions.
