Analyze sequence usage patterns and potential exhaustion risks.
AI agents call PostgreSQL_get_sequence_usage_stats to retrieve information from Postgres without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes sequence usage statistics to identify potential issues (exhaustion risks). It performs queries to gather diagnostic information about PostgreSQL sequences but does not create, modify, delete, or execute arbitrary code.
From the tool's definition Tool name and description indicate analysis and monitoring: 'Analyze sequence usage patterns and potential exhaustion risks.' The verb 'Analyze' and the focus on gathering metrics about sequence behavior are diagnostic read operations without modification.
Documented attack patterns abuse exactly the kind of access PostgreSQL_get_sequence_usage_stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Postgres, and nothing reaches the server without passing your rules. This is the rule we recommend for PostgreSQL_get_sequence_usage_stats:
{
"version": "1",
"default": "deny",
"tools": {
"PostgreSQL_get_sequence_usage_stats": {}
}
}PostgreSQL_get_sequence_usage_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Analyze sequence usage patterns and potential exhaustion risks. It is categorised as a Read tool in the Postgres MCP Server, which means it retrieves data without modifying state.
Register the Postgres MCP server in PolicyLayer and add a rule for PostgreSQL_get_sequence_usage_stats: 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 Postgres. Nothing to install.
PostgreSQL_get_sequence_usage_stats 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 PostgreSQL_get_sequence_usage_stats 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 PostgreSQL_get_sequence_usage_stats. 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.
PostgreSQL_get_sequence_usage_stats is provided by the Postgres MCP server (mukul975/postgres-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Postgres, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
