Return a curated dictionary of well-known RSS/Atom feed URLs by category.
AI agents call popular_feeds to retrieve information from Integrations MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply returns a pre-curated dictionary of RSS/Atom feed URLs organized by category. It performs data retrieval only, has no side effects, does not modify any state, and poses minimal security risk even if misused by an AI agent. The worst-case scenario would be the agent fetching feed content from the returned URLs, which is a read-only operation.
From the tool's definition Tool name 'popular_feeds' and description 'Return a curated dictionary of well-known RSS/Atom feed URLs by category' indicate retrieval of static feed data with no modification or side effects.
Attacks that exploit this kind of access
Return a curated dictionary of well-known RSS/Atom feed URLs by category. It is categorised as a Read tool in the Integrations MCP MCP Server, which means it retrieves data without modifying state.
Register the Integrations MCP server in PolicyLayer and add a rule for popular_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 Integrations MCP. Nothing to install.
popular_feeds 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 popular_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 popular_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.
popular_feeds is provided by the Integrations MCP server (shriram-vasudevan/integrations-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
