AI agents call read_dict_item to retrieve information from UOFastMCP 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 operation on a dictionary item in a U2 UniData/UniVerse database. It queries and retrieves metadata/schema information about a specific dictionary entry without creating, modifying, or deleting any data. The blast radius of misuse is minimal — an attacker could learn about the database structure but cannot alter state or execute arbitrary operations.
From the tool's definition Tool name is 'read_dict_item' and description states 'Read a specific DICT item from a file' — purely retrieves data without modification.
Attacks that exploit this kind of access
Read a specific DICT item from a file. It is categorised as a Read tool in the UOFastMCP MCP Server, which means it retrieves data without modifying state.
Register the UOFast MCP server in PolicyLayer and add a rule for read_dict_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 UOFastMCP. Nothing to install.
read_dict_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 read_dict_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 read_dict_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.
read_dict_item is provided by the UOFast MCP server (rokipark/uofastmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
