reassign_feeds · Inoreader MCP: Risk & Policy

WHAT IT DOES

What reassign_feeds does on Inoreader

AI agents use reassign_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.

WHY IT NEEDS A POLICY

Why reassign_feeds needs a policy

This tool reorganizes/moves feeds between folders, which is a reversible write operation (feeds can be moved back). It modifies the organizational structure of subscriptions but does not delete data or execute code. The bulk nature increases the blast radius slightly, warranting medium severity.

From the tool's definition Move feeds from one folder to another in bulk... Pass from_folder and a map of {new_folder: [stream_id, ...]}

Verdict

reassign_feeds Rate-limited

reassign_feeds stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

How do I enforce a policy on reassign_feeds? +

Register the Inoreader MCP server in PolicyLayer and add a rule for reassign_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.

What risk level is reassign_feeds? +

reassign_feeds is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit reassign_feeds? +

Yes. Add a rate_limit block to the reassign_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.
