AI agents call show_query 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 and displays the definition/source code of an existing GSQL query. It performs a read-only operation analogous to viewing a stored procedure definition. There are no side effects, no data modification, no code execution, and no destructive operations. The blast radius if misused is minimal — an agent could only access query definitions already stored in the database.
From the tool's definition Tool name is 'show_query' and description states it 'Show[s] the content of a GSQL query' — a retrieval operation with no modification or execution of queries.
Attacks that exploit this kind of access
MCP tool: Show the content of a GSQL query. 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 show_query: 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.
show_query 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 show_query 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 show_query. 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.
show_query 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.
