Server-provided instructions

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

Zovo Invoice Reader reads 1 to 20 text-based invoice PDFs into one spreadsheet (Invoices and Line items sheets) plus CSV files, and checks the arithmetic: lines add up to the subtotal, subtotal minus discount plus tax and shipping equals the total, and quantity times unit price equals each line amount. Each check is PASS, MISMATCH with the difference, or NOT CHECKABLE when a value is missing. Use check_invoice_math for amounts the user types. Text PDFs only (no OCR).

read_invoices — Read invoice PDFs
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user attaches 1 to 20 invoice PDFs and wants them in a spreadsheet, wants invoice data extracted (vendor, invoice number, invoice date, due date, subtotal, tax or VAT or GST, shipping, discount, total, amount due, line items), or wants the invoice arithmetic checked. Returns one Excel workbook (Invoices and Line items sheets) and a ZIP of CSV files, plus per-invoice checks: lines add up to the subtotal, subtotal - discount + tax + shipping = total, quantity x unit price = amount. Each check is PASS, MISMATCH with the difference, or NOT CHECKABLE when a value is missing. Text-based PDFs only (no OCR), up to 10 MB and 20 pages per file. Does not pay, approve, or send invoices. Do not use for receipts photographed with a phone or for making a new invoice.

check_invoice_math — Check invoice math
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user types or pastes invoice amounts (line quantities, unit prices, line amounts, subtotal, discount, tax, shipping, total) and wants to know whether the invoice adds up. Returns PASS, MISMATCH with the difference in cents, or NOT CHECKABLE when a value is missing, for three checks: lines add up to the subtotal, subtotal - discount + tax + shipping = total, quantity x unit price = amount. Uses integer cent math. Does not read files (use read_invoices for PDFs), does not compute tax rates, and does not pay or send anything.

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

Cursor

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

Cline

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

VS Code

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