Fetch and parse an RSS feed from URL
AI agents call fetch_rss to retrieve information from ContextForge MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and parses data from an RSS feed—a read-only operation with no ability to modify, delete, or execute code. The action is querying/fetching external content. Severity is low because RSS feeds are typically public, and the blast radius of misuse is limited to retrieving potentially sensitive feed content.
From the tool's definition Tool name 'fetch_rss' and description 'Fetch and parse an RSS feed from URL' indicate retrieval of publicly available RSS feed data with no side effects or modifications.
Attacks that exploit this kind of access
Fetch and parse an RSS feed from URL. It is categorised as a Read tool in the ContextForge MCP Gateway MCP Server, which means it retrieves data without modifying state.
Register the ContextForge MCP Gateway MCP server in PolicyLayer and add a rule for fetch_rss: 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 ContextForge MCP Gateway. Nothing to install.
fetch_rss 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 fetch_rss 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 fetch_rss. 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.
fetch_rss is provided by the ContextForge MCP Gateway MCP server (jrmatherly/mcp-context-forge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
