# update_category Update a category's details. Agent View of the PolicyLayer registry record for `update_category`. HTML page: https://policylayer.com/tools/graysoncadams-mealie-mcp/update-category ## Facts - Tool: `update_category` - Server: Mealie MCP Server (`graysoncadams/mealie-mcp`) — https://policylayer.com/tools/graysoncadams-mealie-mcp.md - Homepage: https://github.com/GraysonCAdams/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 creates or modifies category data in a reversible manner, which aligns with the Write category definition. The scope is limited to category metadata updates with no ability to delete or execute arbitrary operations. Severity is low because misuse would only affect recipe organization/categorization, with minimal blast radius on the Mealie instance and no financial or data destruction implications. From the tool's own definition: "Tool name 'update_category' and description 'Update a category's details' indicate modification of existing data. The word 'update' is a classic Write operation that modifies data reversibly." ## 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. Every call changes real data in your Mealie MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
