List recipe tags.
AI agents call list_tags 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 retrieves and displays existing recipe tags without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval operation that has no blast radius if misused by an AI agent—the worst outcome would be retrieving tag information that is already accessible in the system.
From the tool's definition Tool name 'list_tags' and description 'List recipe tags' indicate a query/retrieval operation with no modification or execution of side effects.

List recipe tags. 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 list_tags: 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.
list_tags 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 list_tags 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 list_tags. 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.
list_tags 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.
