AI agents call list_skills 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 retrieves information about available skills without creating, modifying, deleting, or executing any operations. It is a pure read operation that enumerates metadata. The low severity reflects minimal blast radius if misused by an AI agent—listing skills poses no direct harm to system state, data integrity, or external resources.
From the tool's definition Tool name 'list_skills' and description 'List all available skills with their descriptions and capabilities' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List all available skills with their descriptions and capabilities. 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_skills: 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_skills 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_skills 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_skills. 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_skills 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.
