Server-provided instructions

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

Zovo Invoice Ledger turns several supplier invoices (rows, invoice PDFs with selectable text, or pasted invoice text) into one Excel and CSV ledger with supplier, invoice number, dates, net, tax by rate, gross and currency, totals per supplier and per tax rate, and flags for duplicate invoice numbers and totals that do not add up. Prefer the invoices rows when the values are in the chat. Share the totals, the flagged invoices verbatim and the download links.

generate_invoice_ledger — Generate invoice ledger
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants several invoices in one spreadsheet ("put these invoices into Excel", "invoice log from these PDFs", "purchase ledger", "VAT summary by rate", "check these invoices for duplicates"). Send the invoices as rows when their values are in the chat or a screenshot; send attached invoice PDFs (selectable text) in files; send pasted invoice text in invoice_texts (one string per invoice), and use text only as a fallback. Returns an Excel ledger (supplier, invoice number, invoice and due date, currency, net, tax per rate, tax total, gross, status) with By supplier, By tax rate and Checks sheets, and a CSV. Flags totals that do not equal net + tax, tax that does not match its rate, and duplicate invoice numbers per supplier. Reads header totals only, not line items. Does not read scanned images, convert currencies, file tax returns, or say whether tax is reclaimable.

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-invoice-ledger-mcp https://invoice-ledger.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-invoice-ledger-mcp --url https://invoice-ledger.zovo.one/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable zovo-invoice-ledger-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "zovo-invoice-ledger-mcp": {
      "url": "https://invoice-ledger.zovo.one/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "zovo-invoice-ledger-mcp": {
      "type": "streamableHttp",
      "url": "https://invoice-ledger.zovo.one/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start zovo-invoice-ledger-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "zovo-invoice-ledger-mcp": {
      "type": "http",
      "url": "https://invoice-ledger.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-invoice-ledger-mcp https://invoice-ledger.zovo.one/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://invoice-ledger.zovo.one/mcp

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-invoice-ledger-mcp": {
      "serverUrl": "https://invoice-ledger.zovo.one/mcp"
    }
  }
}
