Zovo Spreadsheet Compare MCP

An MCP server that compares two versions of a spreadsheet (CSV or Excel) and lists the differences, including rows added, removed, and changed cell by cell with old and new values, numeric changes, and percent changes. It handles automatic key column detection, reordered rows, renamed columns, and various number formats.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Compares two versions of a spreadsheet. Use compare_spreadsheets to list all added, removed and changed rows; use summarize_changes for counts and the biggest changes by column. Give the user the download links: the full change set is in the files.

compare_spreadsheets — Compare spreadsheets

Advertised by the server during the last successful anonymous check.

Advertised read-only

Use this when the user has two versions of the same spreadsheet (CSV or Excel: price list, inventory, roster, budget, product catalog, CRM export) and wants to "compare two excel files", "compare two spreadsheets", "find the differences between two csv files", "what changed between these files" or "list what changed". Matches rows by a key column it detects (or key_columns), lists all added, removed and changed rows with each changed cell old -> new, numeric change and percent, plus renamed/moved columns and key changes, and returns an Excel workbook (Summary, Changed, Cell changes, Added, Removed, annotated new version) and a changes CSV. Does not merge or join two different tables (e.g. customers + orders), does not compare Word or PDF documents, and does not edit either file.

summarize_changes — Summarize changes

Advertised by the server during the last successful anonymous check.

Advertised read-only

Use this when the user has two versions of a spreadsheet and wants a summary rather than a full list: "how many prices went up", "which columns changed the most", "biggest changes between these two files", "average price increase". Returns counts (changed, added, removed rows), per-column statistics (cells changed, increases, decreases, total and average percent change, largest increase and decrease) and the biggest single changes, with the same Excel and CSV downloads. Use compare_spreadsheets for the row-by-row list. Does not forecast or explain why values changed.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http zovo-spreadsheet-compare-mcp https://sheet-compare.zovo.one/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add zovo-spreadsheet-compare-mcp --url https://sheet-compare.zovo.one/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable zovo-spreadsheet-compare-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "zovo-spreadsheet-compare-mcp": {
      "url": "https://sheet-compare.zovo.one/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "zovo-spreadsheet-compare-mcp": {
      "type": "streamableHttp",
      "url": "https://sheet-compare.zovo.one/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start zovo-spreadsheet-compare-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "zovo-spreadsheet-compare-mcp": {
      "type": "http",
      "url": "https://sheet-compare.zovo.one/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http zovo-spreadsheet-compare-mcp https://sheet-compare.zovo.one/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "zovo-spreadsheet-compare-mcp": {
      "serverUrl": "https://sheet-compare.zovo.one/mcp"
