Get RSSHub feed content. If route is provided, fetch specific feed. If no route is provided, fetch all subscribed feeds. Use RSSHUB_INSTANCE environment variable to configure custom instance.
AI agents call get_feed to retrieve information from RSSHub 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 content based on provided routes or returns subscribed feeds. It performs read-only operations with no side effects—it does not create, modify, delete, execute code, or move money. The worst-case misuse scenario (retrieving sensitive information from accessible feeds) has limited blast radius since the tool merely queries existing feeds without altering system state.
From the tool's definition Tool name 'get_feed' and description 'fetch specific feed' and 'fetch all subscribed feeds' indicates data retrieval with no modification or destructive capability.
Documented attack patterns abuse exactly the kind of access get_feed gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and RSSHub MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_feed:
{
"version": "1",
"default": "deny",
"tools": {
"get_feed": {}
}
}get_feed is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get RSSHub feed content. If route is provided, fetch specific feed. If no route is provided, fetch all subscribed feeds. Use RSSHUB_INSTANCE environment variable to configure custom instance. It is categorised as a Read tool in the RSSHub MCP Server MCP Server, which means it retrieves data without modifying state.
Register the RSSHub MCP Server MCP server in PolicyLayer and add a rule for get_feed: 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 RSSHub MCP Server. Nothing to install.
get_feed 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_feed 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_feed. 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_feed is provided by the RSSHub MCP Server MCP server (panxiande/rsshub-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from RSSHub 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.
