AI agents call list_encryption_profiles to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays existing encryption profile configuration data. It performs a read-only query operation without creating, modifying, deleting, or executing any code. The information returned concerns local security configurations rather than sensitive data itself. The blast radius of misuse is limited to information disclosure about available encryption methods.
From the tool's definition Tool name 'list_encryption_profiles' and description 'List local encryption profiles' indicate a query/retrieval operation with no modification or execution of external systems.
Attacks that exploit this kind of access
List local encryption profiles for secure fields and exports. It is categorised as a Read tool in the Todos MCP Server, which means it retrieves data without modifying state.
Register the Todos MCP server in PolicyLayer and add a rule for list_encryption_profiles: 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 Todos. Nothing to install.
list_encryption_profiles 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_encryption_profiles 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_encryption_profiles. 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_encryption_profiles is provided by the Todos MCP server (@hasna/todos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
