WHAT IT DOES

What apply_memory_config does on Strata Memory MCP Server

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

WHY IT NEEDS A POLICY

Why apply_memory_config needs a policy

This tool modifies system state by persisting configuration and initializing storage infrastructure (directories, databases). While not fully destructive (since initialization is reversible), it creates and configures data structures. The 'hot reload' capability means changes apply without restart, potentially affecting live agent behavior.

From the tool's definition The tool description states it will 'persist config, initialize Palace directories, ChromaDB, SQLite' and supports 'hot reload'. These are configuration write operations that create or modify system state (directory initialization, database setup).

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

How do I enforce a policy on apply_memory_config? +

Register the Strata Memory MCP Server MCP server in PolicyLayer and add a rule for apply_memory_config: 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 Strata Memory MCP Server. Nothing to install.

What risk level is apply_memory_config? +

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

Can I rate-limit apply_memory_config? +

Yes. Add a rate_limit block to the apply_memory_config 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.

How do I block apply_memory_config completely? +

Set action: deny in the PolicyLayer policy for apply_memory_config. 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.

What MCP server provides apply_memory_config? +

apply_memory_config is provided by the Strata Memory MCP Server MCP server (sherryli-vc/strata-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
