AI agents call list_rosters to retrieve information from ComplyOS without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
List operations are inherently read-only—they retrieve and present data without modification, deletion, or execution. In a compliance auditing system, listing rosters (likely enrollment or organizational structures) is a foundational query function. No approval, confirmation, or write-related naming appears in the tool name.
From the tool's definition Tool name 'list_rosters' follows read-only naming pattern (list/get/fetch). Description is empty, limiting direct evidence.
Attacks that exploit this kind of access
list_rosters. It is categorised as a Read tool in the ComplyOS MCP Server, which means it retrieves data without modifying state.
Register the ComplyOS MCP server in PolicyLayer and add a rule for list_rosters: 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 ComplyOS. Nothing to install.
list_rosters 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 list_rosters 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 list_rosters. 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.
list_rosters is provided by the ComplyOS MCP server (simongonzalezdc/complyos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
