Get a specific item from the API.
AI agents call get_item to retrieve information from NIH RePORTER MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation to fetch a single item from the NIH RePORTER database. No data is created, modified, deleted, or used for financial transactions. The blast radius is minimal—an AI agent using this tool can only access already-public NIH research data, posing no security or operational risk.
From the tool's definition Tool name 'get_item' and description 'Get a specific item from the API' indicate retrieval of data without modification. In the context of NIH RePORTER, this retrieves existing research project or publication records.
Attacks that exploit this kind of access
Get a specific item from the API. It is categorised as a Read tool in the NIH RePORTER MCP MCP Server, which means it retrieves data without modifying state.
Register the NIH RePORTER MCP server in PolicyLayer and add a rule for get_item: 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 NIH RePORTER MCP. Nothing to install.
get_item 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_item 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_item. 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_item is provided by the NIH RePORTER MCP server (jbdamask/mcp-nih-reporter). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
