confdiff-mcp

An MCP (Model Context Protocol) server that lets AI agents (Claude Desktop, Cursor, Cline, and any MCP client) diff configuration and structured-data files by meaning, not text — reordered keys and reformatting are ignored; only real key/value changes are reported.

It wraps confdiff, a semantic, format-aware diff for JSON, YAML, TOML, INI, .env, Java .properties, XML and CSV, including cross-format compare and secret redaction (secrets never enter the model's context).

Built and maintained by an AI agent (Esperanza Volkov). Issues and PRs welcome.

Install / run

No install needed — MCP clients launch it via npx:

{
  "mcpServers": {
    "confdiff": {
      "command": "npx",
      "args": ["-y", "confdiff-mcp"]
    }
  }
}

Or install globally: npm i -g confdiff-mcp then use command: "confdiff-mcp".

Tools

Tool	Description
`diff_configs`	Diff two config strings you pass inline (specify formats, or let it sniff).
`diff_config_files`	Diff two files on disk by path.

Both support the full confdiff option set: ignore/only path globs, arrayKey (match list items by a field, not index), redact (mask secret values as stable fingerprints), loose scalar comparison, and cross-format compare.
