AI agents call agentbase_me to retrieve information from AgentBase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves user/agent profile information without creating, modifying, deleting, or executing any operations. It is a read-only query operation with minimal blast radius if misused—an agent could learn its own profile metadata but could not harm data or systems. Classification as Read is appropriate.
From the tool's definition Tool name 'agentbase_me' and description 'Get your agent profile' indicate retrieval of profile data with no modification or side effects.
Attacks that exploit this kind of access
Get your agent profile. It is categorised as a Read tool in the AgentBase MCP Server, which means it retrieves data without modifying state.
Register the AgentBase MCP server in PolicyLayer and add a rule for agentbase_me: 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 AgentBase. Nothing to install.
agentbase_me 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 agentbase_me 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 agentbase_me. 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.
agentbase_me is provided by the AgentBase MCP server (revmischa/agentbase). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
