AI agents call list_subagents to retrieve information from AGI-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs information retrieval only. It queries available subagents and returns their metadata (descriptions and specializations). There are no side effects, data modifications, code execution, destructive operations, or financial implications. The blast radius of misuse is minimal—an agent could only discover what subagents exist, with no ability to invoke them or cause harm via this tool alone.
From the tool's definition Tool name 'list_subagents' and description 'List all available subagents with their descriptions and specializations' indicate a read-only operation that retrieves and queries information about subagents without modifying any state or triggering external…
Attacks that exploit this kind of access
List all available subagents with their descriptions and specializations. It is categorised as a Read tool in the AGI-MCP MCP Server, which means it retrieves data without modifying state.
Register the AGI- MCP server in PolicyLayer and add a rule for list_subagents: 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 AGI-MCP. Nothing to install.
list_subagents 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_subagents 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_subagents. 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_subagents is provided by the AGI- MCP server (muah1987/agi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
