AI agents call get_udf to retrieve information from TG_MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves User Defined Function (UDF) files from the TigerGraph database without modifying, executing, or deleting them. It is a straightforward Read operation that queries existing resources. While UDF files could contain executable code, this tool only retrieves their definitions/metadata—it does not execute them (that would be a separate 'run' operation).
From the tool's definition Tool name 'get_udf' and description 'Get UDF files' indicate a retrieval operation with no modification or execution of code. The verb 'Get' explicitly denotes a read-only query action.
Attacks that exploit this kind of access
MCP tool: Get UDF files. It is categorised as a Read tool in the TG_MCP MCP Server, which means it retrieves data without modifying state.
Register the TG_ MCP server in PolicyLayer and add a rule for get_udf: 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 TG_MCP. Nothing to install.
get_udf 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_udf 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_udf. 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_udf is provided by the TG_ MCP server (muzain187/tg_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
