List all keys currently stored in this project
AI agents call memory_list to retrieve information from Claude Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about stored memory keys without creating, modifying, or deleting data. It has no side effects beyond information disclosure, making it a Read category tool with low severity. The narrow scope (listing keys only, not reading their values) and non-destructive nature justify low severity.
From the tool's definition Tool name 'memory_list' and description 'List all keys currently stored in this project' indicate a query operation that retrieves and enumerates stored data without modification.
Attacks that exploit this kind of access
List all keys currently stored in this project. It is categorised as a Read tool in the Claude Memory MCP Server, which means it retrieves data without modifying state.
Register the Claude Memory MCP server in PolicyLayer and add a rule for memory_list: 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 Claude Memory. Nothing to install.
memory_list 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 memory_list 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 memory_list. 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.
memory_list is provided by the Claude Memory MCP server (santicalderon/claude-memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
