Assign feeds to folders in bulk. Pass a map of {folder_name: [stream_id, ...]}. Typical workflow: call get_uncategorized_feeds first, decide categories, then call this tool. Each feed assignment costs 1 Zone 2 request.
AI agents use categorize_feeds to create or update resources in Inoreader — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Inoreader environment.
The tool modifies feed-to-folder assignments, which is a reversible write operation (feeds can be recategorized). This is not a destructive delete operation, nor does it execute arbitrary code or handle financial transactions. It organizes data by moving resources between categories.
From the tool's definition 'Assign feeds to folders in bulk' and 'call this tool' to modify feed categorizations; the description explicitly indicates this performs reversible modifications to feed organization state.

Assign feeds to folders in bulk. Pass a map of {folder_name: [stream_id, ...]}. Typical workflow: call get_uncategorized_feeds first, decide categories, then call this tool. Each feed assignment costs 1 Zone 2 request. It is categorised as a Write tool in the Inoreader MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Inoreader MCP server in PolicyLayer and add a rule for categorize_feeds: 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 Inoreader. Nothing to install.
categorize_feeds is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the categorize_feeds 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 categorize_feeds. 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.
categorize_feeds is provided by the Inoreader MCP server (justmytwospence/inoreader-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
