WHAT IT DOES

What list_ferry_diagrams does on Sanka MCP Server

AI agents call list_ferry_diagrams to retrieve information from Sanka MCP Server 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_ferry_diagrams is rated Low

Even though list_ferry_diagrams only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_ferry_diagrams safely

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

list_ferry_diagrams Allowed

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

  "tools": {
    "list_ferry_diagrams": {}
  }
}

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

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