Lossless Context MCP

The flight recorder for your agent's context. A persistent, hook-fed ledger of every file version your coding agent was shown - so a compaction can't destroy the working set, a subagent fleet doesn't pay for the same files N times, and you can prove afterward exactly what the model saw. It runs locally over stdio via the published package.

People connecting filesystem tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

  "mcpServers": {
    "northtekdevs-lossless-context-mcp": {
      "command": "npx",
      "args": [
        "-y",
