HTML page: https://policylayer.com/tools/app-businys-mcp-server/update-invoice ## Facts - Tool: `update_invoice` - Server: Businys (`@businys/mcp-server`) — https://policylayer.com/tools/app-businys-mcp-server.md - Install: `npx -y @businys/mcp-server` - Homepage: https://github.com/hiatys/businys-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "update_invoice", "arguments": {} } } ``` ## Why update_invoice is rated Medium This tool modifies invoice data, which are critical financial documents. While not destructive (invoices can be corrected), and not moving money directly, unauthorized updates to invoices represent a high-severity write operation with potential for fraud, billing errors, or financial disputes. Misuse could alter amounts, dates, or payment terms. From the tool's own definition: "Tool name 'update_invoice' and description 'Update an invoice' indicate modification of financial records. The sibling tools include 'invoices' (mentioned in server description) and financial management capabilities." ## Use case AI agents use update_invoice to create or update resources in Businys, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Businys environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
