HTML page: https://policylayer.com/tools/stateset-mcp-server/stateset-add-cart-item ## Facts - Tool: `stateset_add_cart_item` - Server: Stateset (`stateset/stateset-mcp-server`) — https://policylayer.com/tools/stateset-mcp-server.md - Homepage: https://github.com/stateset/stateset-mcp-server - 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": "stateset_add_cart_item", "arguments": {} } } ``` ## Why stateset_add_cart_item is rated Medium This tool creates or modifies shopping cart data reversibly. It does not execute arbitrary code, delete data irreversibly, or move money directly. While cart operations can lead to financial transactions downstream, the tool itself only performs a write operation (adding/updating cart items). From the tool's own definition: "Tool description states 'Adds an item to a shopping cart' and 'quantity is added', indicating it modifies cart state by creating or updating cart entries." ## Use case AI agents use stateset_add_cart_item to create or update resources in Stateset, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Stateset environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
