remember · Chronos MCP: Risk & Policy

WHAT IT DOES

What remember does on Chronos MCP

AI agents use remember to create or update resources in Chronos MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Chronos MCP environment.

WHY IT NEEDS A POLICY

Why remember needs a policy

The tool name 'remember' strongly implies storing or writing data to the persistent memory/knowledge graph system. The description is empty, so confidence is reduced. Based on the server's purpose and sibling tools (get_memory, forget, add_event, etc.), 'remember' likely creates or updates memory entries — a Write operation.

From the tool's definition Tool name 'remember' on a server described as providing 'persistent local memory and structured knowledge graph to track project states, tasks, and historical decisions'

Verdict

remember Rate-limited

remember stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Questions about remember

What does the remember tool do? +

remember. It is categorised as a Write tool in the Chronos MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on remember? +

Register the Chronos MCP server in PolicyLayer and add a rule for remember: 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 Chronos MCP. Nothing to install.

What risk level is remember? +

remember is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit remember? +
