HTML page: https://policylayer.com/tools/sankahq-sanka-mcp/create-invoice ## Facts - Tool: `create_invoice` - Server: Sanka MCP Server (`sankahq/sanka-mcp`) — https://policylayer.com/tools/sankahq-sanka-mcp.md - Homepage: https://github.com/sankaHQ/sanka-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": "create_invoice", "arguments": {} } } ``` ## Why create_invoice is rated Medium This tool creates financial documents (invoices) which are business-critical records. While invoice creation itself is reversible (invoices can typically be voided or deleted in accounting systems), it creates enforceable financial records that trigger downstream business processes. It modifies financial state by generating a new invoice, making it Write rather than Read. From the tool's own definition: "Tool name 'create_invoice' and description 'Create an invoice in Sanka from explicit customer, line item, and invoice-level custom_fields data' clearly indicate data creation." ## Use case AI agents use create_invoice to create or update resources in Sanka MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sanka MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
