Use invoice processing with Claude Desktop

Pull fields out of invoice text, match it to purchase orders and flag fraud risk. Connect Claude Desktop to the WingMan MCP gateway once and these tools are available in every conversation.

1. Connect Claude Desktop

Open Settings, then Developer, then Edit Config, and add this to claude_desktop_config.json. Restart Claude Desktop. Claude Desktop's config file runs local commands, so the remote server is reached through the mcp-remote bridge (needs Node.js).

{
  "mcpServers": {
    "wingman": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://wingmanprotocol.com/mcp",
        "--header",
        "X-Wingman-Tools:full"
      ]
    }
  }
}

2. The tools you get

Names and descriptions come straight from the live tool registry.

• invoice_extractExtract structured fields from raw invoice TEXT (vendor, number, dates, line items, totals).
• invoice_matchThree-way match an invoice against a list of purchase orders (amount %-diff + line-item similarity → best open PO, discrepancies, auto-appr…
• invoice_fraud_checkRule-based fraud risk for an invoice (duplicate / vendor-anomaly / round-amount / rush-terms) → score 0-100 + LOW/MEDIUM/HIGH/CRITICAL + re…

These tools sit outside the default tool list, so the config above sets X-Wingman-Tools: full to load the whole catalogue. Without it, your agent can still reach them with discover_tools, then get_tool_schema, then tools/call.

3. Ask for it

Give Claude Desktop a task that needs it, for example “use invoice_extract from wingman”. The tool call goes to https://wingmanprotocol.com/mcp and the result comes back into the conversation.
