WHAT IT DOES

What serac_list does on Serac

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

RISK

Why serac_list is rated Low

This tool retrieves and enumerates stored keys, which is a classic Read operation with no side effects. It performs a simple listing/query operation similar to 'ls' or 'list' commands. The prefix filter is a retrieval parameter, not a modification. No data is created, modified, deleted, or financial operations are involved.

From the tool's definition Tool name 'serac_list' and description 'List keys in a namespace with optional prefix filter' indicate a read-only operation that queries existing data without modification.

RECOMMENDED RULE

The rule that runs serac_list safely

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

serac_list Allowed

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

View as policy code

policy.json

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

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

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