AI agents call list_agent_adapters 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 queries and returns information about locally configured adapters. It performs a read-only operation with no side effects, matching the Read category definition of 'retrieves or queries data'. The blast radius is minimal since it only exposes existing configuration information.
From the tool's definition Tool name is 'list_agent_adapters' and description states 'List locally configured agent run adapters'. The verb 'list' indicates retrieval of existing configuration data without modification or execution.
Attacks that exploit this kind of access
List locally configured agent run adapters (stdio, tmux, script). 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_agent_adapters: 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_agent_adapters 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_agent_adapters 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_agent_adapters. 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_agent_adapters 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.
