Get the knowledge chain for a memory, showing how it evolved.
AI agents call get_memory_chain to retrieve information from memro MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a retrieval operation to display the evolution history of a memory entry. It neither creates, modifies, deletes, executes commands, nor involves financial transactions. The action is informational and has no side effects on the data store beyond querying existing information. Classified as Read with low severity due to the minimal blast radius of retrieving memory history data.
From the tool's definition Tool description states it retrieves "the knowledge chain for a memory, showing how it evolved" - a read-only query operation that retrieves historical information without modification or side effects.

Get the knowledge chain for a memory, showing how it evolved. It is categorised as a Read tool in the memro MCP Server MCP Server, which means it retrieves data without modifying state.
Register the memro MCP Server MCP server in PolicyLayer and add a rule for get_memory_chain: 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 memro MCP Server. Nothing to install.
get_memory_chain 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 get_memory_chain 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 get_memory_chain. 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.
get_memory_chain is provided by the memro MCP Server MCP server (memrohq/memro-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
