list_tables
AI agents call list_tables to retrieve information from Mcp Ohmy Sql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about tables in a database schema without modifying, executing, or deleting data. It is a standard schema discovery operation with minimal blast radius. Low confidence (0.85 instead of higher) due to empty description, but tool name and sibling context provide strong evidence.
From the tool's definition Tool name 'list_tables' indicates retrieval of table metadata; sibling tools include 'get_all_database_details', 'get_schema_details', and 'list_databases' which are all Read operations.
Attacks that exploit this kind of access
list_tables. It is categorised as a Read tool in the Mcp Ohmy Sql MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ohmy Sql MCP server in PolicyLayer and add a rule for 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 Mcp Ohmy Sql. Nothing to install.
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 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 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.
list_tables is provided by the Mcp Ohmy Sql MCP server (machu-gwu/mcp_ohmy_sql-project). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
