List all tables in the current database
AI agents call timescale_list_tables to retrieve information from TigerData-mcp-server 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 that retrieves information about database tables. There are no side effects, no data modification, no code execution, and no destructive actions. The blast radius of misuse is minimal—an attacker could enumerate the schema but cannot access data, modify tables, or cause damage.
From the tool's definition Tool name is 'timescale_list_tables' and description states 'List all tables in the current database'. This is a query/list operation that retrieves metadata about database schema without modifying or executing code.
Attacks that exploit this kind of access
List all tables in the current database. It is categorised as a Read tool in the TigerData-mcp-server MCP Server, which means it retrieves data without modifying state.
Register the TigerData-mcp-server MCP server in PolicyLayer and add a rule for timescale_list_tables: 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 TigerData-mcp-server. Nothing to install.
timescale_list_tables 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 timescale_list_tables 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 timescale_list_tables. 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.
timescale_list_tables is provided by the TigerData-mcp-server MCP server (thesurfingcoder/tigerdata-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
