Check if a newer version of the Memory MCP server is available.
AI agents call memory_check_update to retrieve information from Claude Memory MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only check against version information (likely a remote registry or local metadata). It retrieves data about available versions but does not install, execute, modify, or delete anything. The operation has no side effects and is purely informational, making it a Read category risk with low severity.
From the tool's definition Tool name 'memory_check_update' and description 'Check if a newer version of the Memory MCP server is available' indicate a query/retrieval operation that checks version information without modifying any data or triggering external operations.

Check if a newer version of the Memory MCP server is available. It is categorised as a Read tool in the Claude Memory MCP MCP Server, which means it retrieves data without modifying state.
Register the Claude Memory MCP server in PolicyLayer and add a rule for memory_check_update: 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 MCP. Nothing to install.
memory_check_update 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_check_update 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_check_update. 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_check_update is provided by the Claude Memory MCP server (navid-kianfar/claude-memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
