Ejecuta consultas predefinidas comunes para explorar la base de datos
AI agents call execute_common_queries to retrieve information from MCP PostgreSQL Read-Only Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool executes predefined common queries for database exploration on a read-only server that only permits SELECT statements. Since the queries are predefined and the server enforces read-only access, there is no risk of data modification. The blast radius is low as it can only retrieve data.
From the tool's definition 'consultas predefinidas comunes para explorar la base de datos' (predefined common queries to explore the database); server is described as 'read-only access' with 'SELECT queries only' and 'preventing any data modification operations'
Attacks that exploit this kind of access
Ejecuta consultas predefinidas comunes para explorar la base de datos. It is categorised as a Read tool in the MCP PostgreSQL Read-Only Server MCP Server, which means it retrieves data without modifying state.
Register the MCP PostgreSQL Read-Only Server MCP server in PolicyLayer and add a rule for execute_common_queries: 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 PostgreSQL Read-Only Server. Nothing to install.
execute_common_queries 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 execute_common_queries 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 execute_common_queries. 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.
execute_common_queries is provided by the MCP PostgreSQL Read-Only Server MCP server (japentaca/mcp-postgres-readonly). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
