Fetch RSS items from the Fever API since a given item ID.
AI agents call get_items to retrieve information from RSS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves RSS feed items without creating, modifying, deleting, or executing any operations. It is a simple data retrieval function (fetch) that has no side effects or ability to alter state. The blast radius of misuse is minimal—an agent could fetch excessive data but cannot damage or alter feeds. This clearly falls under the Read category.
From the tool's definition Tool description states "Fetch RSS items" which is a retrieval operation with no modification capability. The server description emphasizes "retrieval of feeds, groups, and items" as distinct from write actions like "read/save actions".
Documented attack patterns abuse exactly the kind of access get_items gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and RSS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_items:
{
"version": "1",
"default": "deny",
"tools": {
"get_items": {}
}
}get_items is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fetch RSS items from the Fever API since a given item ID. It is categorised as a Read tool in the RSS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the RSS MCP Server MCP server in PolicyLayer and add a rule for get_items: 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 RSS MCP Server. Nothing to install.
get_items 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_items 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_items. 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_items is provided by the RSS MCP Server MCP server (weekend-project-space/rss-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from RSS MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
