Read a value from Claude
AI agents call memory_read 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 previously stored memory values without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that queries persisted memory state, fitting the 'Read' category definition of data retrieval with no side effects.
From the tool's definition Tool name 'memory_read' and description 'Read a value from Claude' explicitly indicates retrieval of stored data with no modification or side effects.
Attacks that exploit this kind of access
Read a value from Claude. 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_read: 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_read 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_read 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_read. 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_read 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.
memory_read is one line of Claude Memory's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
