AI agents call check_feeds to retrieve information from Noapi Google Search without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to check or retrieve feed data (news, RSS, social media feeds, etc.). Feed checking is a read operation with no data modification, deletion, or execution of arbitrary code. The lack of destructive, financial, or execution capabilities places this squarely in the Read category with low severity—misuse would only expose information, not cause harm.
From the tool's definition Tool name 'check_feeds' combined with sibling tool 'get_feed_items' indicates feed retrieval functionality. Server description mentions 'live feeds' as a read-only capability. No description provided for this specific tool, lowering confidence slightly.
Documented attack patterns abuse exactly the kind of access check_feeds gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Noapi Google Search, and nothing reaches the server without passing your rules. This is the rule we recommend for check_feeds:
{
"version": "1",
"default": "deny",
"tools": {
"check_feeds": {}
}
}check_feeds is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

check_feeds. It is categorised as a Read tool in the Noapi Google Search MCP Server, which means it retrieves data without modifying state.
Register the Noapi Google Search MCP server in PolicyLayer and add a rule for check_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 Noapi Google Search. Nothing to install.
check_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 check_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 check_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.
check_feeds is provided by the Noapi Google Search MCP server (vincentkaufmann/noapi-google-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
