Fetch a category by UUID.
AI agents call get_category to retrieve information from Mcp Mealie without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves category data by identifier. The verb 'fetch' and the absence of any mention of modification, deletion, or execution confirms this is a read-only operation. No data is created, modified, or destroyed, and no external operations are triggered. The blast radius of misuse is minimal.
From the tool's definition Tool name 'get_category' and description 'Fetch a category by UUID' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Fetch a category by UUID. It is categorised as a Read tool in the Mcp Mealie MCP Server, which means it retrieves data without modifying state.
Register the Mcp Mealie MCP server in PolicyLayer and add a rule for get_category: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Mealie. Nothing to install.
get_category is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_category rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_category. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_category is provided by the Mcp Mealie MCP server (obrien-matthew/mcp-mealie). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
