Resili Replay MCP Server

ResiliReplay is the MCP reliability engine behind proof-carrying recovery changes: inspect one reviewed target, inject a deterministic fault, bound retries and duplicate effects, preserve evidence, and turn the failure into an executable regression. It runs locally over stdio via the published package.

People who work with regression testing, developer tools and fault injection and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Resili Replay

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add aliengineering-byte-resilireplay -- npx -y resilireplay

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "aliengineering-byte-resilireplay": {
      "command": "npx",
      "args": [
        "-y",
        "resilireplay"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
