What analyze_sequence_usage does on Postgres
AI agents call analyze_sequence_usage to retrieve information from Postgres without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why analyze_sequence_usage is rated Low
This tool reads database metadata about sequences and performs predictive analysis on sequence exhaustion. It is a diagnostic/monitoring tool that queries existing data without modifying state, executing commands, or deleting anything. The sibling tools (analyze_buffer_utilization, analyze_query_plans, etc.) confirm this server contains analysis and monitoring functions primarily classified as Read operations.
From the tool's definition Tool name 'analyze_sequence_usage' and description 'Analyze sequence usage and predict when sequences might be exhausted' indicate data retrieval and analysis operations with no modification, deletion, or execution of arbitrary code.
Attacks that exploit this kind of access
The rule that runs analyze_sequence_usage safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Postgres, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For analyze_sequence_usage, this is the rule to start with:
analyze_sequence_usage is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Postgres, apply this rule, and every analyze_sequence_usage call is checked against it from then on.
Questions about analyze_sequence_usage
Analyze sequence usage and predict when sequences might be exhausted. 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 analyze_sequence_usage: 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.
analyze_sequence_usage 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 analyze_sequence_usage 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 analyze_sequence_usage. 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.
analyze_sequence_usage 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.
