AI agents call memento_autonomy_status to retrieve information from Memento without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only status query. It retrieves information about an agent's autonomy level and operational metrics without modifying, executing, or destructively altering any data or system state. The [DEPRECATED] marker suggests it is legacy and unlikely to pose elevated risk.
From the tool's definition Tool name is 'memento_autonomy_status' and description indicates it 'Get[s] detailed status of the autonomous agent: current level, cycle count' — a query operation that retrieves state information with no side effects.

[DEPRECATED] Get detailed status of the autonomous agent: current level, cycle count,. It is categorised as a Read tool in the Memento MCP Server, which means it retrieves data without modifying state.
Register the Memento MCP server in PolicyLayer and add a rule for memento_autonomy_status: 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 Memento. Nothing to install.
memento_autonomy_status 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 memento_autonomy_status 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 memento_autonomy_status. 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.
memento_autonomy_status is provided by the Memento MCP server (joyciakira/memento). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
