WHAT IT DOES

What list_sequences does on Mcpg

AI agents call list_sequences to retrieve information from Mcpg without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_sequences is rated Low

Based on the name 'list_sequences', this tool appears to retrieve or enumerate database sequences, which is a non-destructive query operation. Despite an empty description, the naming convention strongly suggests a Read operation that queries system metadata.

From the tool's definition Tool name 'list_sequences' indicates a listing/query operation that retrieves database sequence metadata without modification. The tool name pattern 'list_*' is a common Read operation in database contexts.

RECOMMENDED RULE

The rule that runs list_sequences safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcpg, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_sequences, this is the rule to start with:

list_sequences Allowed

list_sequences is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_sequences": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcpg, apply this rule, and every list_sequences call is checked against it from then on.
