HTML page: https://policylayer.com/tools/nikopol666-mealie-mcp/update-category ## Facts - Tool: `update_category` - Server: Mealie MCP Server (`nikopol666/mealie-mcp`) — https://policylayer.com/tools/nikopol666-mealie-mcp.md - Homepage: https://github.com/nikopol666/mealie-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_category", "arguments": {} } } ``` ## Why update_category is rated Medium This tool modifies an existing recipe category, which is a reversible operation. The blast radius is low because categories are metadata with minimal cascading risk—other recipes referencing the category will continue to work, and the change can be undone by updating again. No data is deleted, financial transactions occur, or code is executed. From the tool's own definition: "Tool name 'update_category' and description 'Update an existing recipe category in Mealie' indicate modification of existing data. The verb 'update' is characteristic of reversible write operations." ## Use case AI agents use update_category to create or update resources in Mealie MCP Server, usually the action step of a workflow, after the agent has gathered context.
