Fetch a single entry by numeric id.
AI agents call get_entry to retrieve information from Feedbagel 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 data (a single RSS feed entry) without creating, modifying, deleting, or executing operations. The verb 'Fetch' and the read-only nature of querying by ID confirm it is a Read operation. Low severity because retrieval of RSS entries poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'get_entry' and description 'Fetch a single entry by numeric id' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Fetch a single entry by numeric id. It is categorised as a Read tool in the Feedbagel MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Feedbagel MCP Server MCP server in PolicyLayer and add a rule for get_entry: 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 Feedbagel MCP Server. Nothing to install.
get_entry 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_entry 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_entry. 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_entry is provided by the Feedbagel MCP Server MCP server (prototypr/feedbagel-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
