📝 [MODIFY EXISTING] Update an existing memory bank file for a specific project. Use this to modify files that already exist. Automatically creates version history. Verifies file exists before updating and provides context about changes.
AI agents use memory_bank_update to create or update resources in Memory Bank Mcp Mongodb — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Memory Bank Mcp Mongodb environment.
This tool creates or modifies data reversibly. While it updates files in a MongoDB-backed system, the operation is not destructive (data is not deleted or irreversibly lost) and includes version history tracking, allowing changes to be reverted.
From the tool's definition Tool description states '[MODIFY EXISTING] Update an existing memory bank file' and 'Automatically creates version history.' The verb 'Update' and 'modify files that already exist' indicate reversible data modification.

📝 [MODIFY EXISTING] Update an existing memory bank file for a specific project. Use this to modify files that already exist. Automatically creates version history. Verifies file exists before updating and provides context about changes. It is categorised as a Write tool in the Memory Bank Mcp Mongodb MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Memory Bank Mcp Mongodb MCP server in PolicyLayer and add a rule for memory_bank_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 Memory Bank Mcp Mongodb. Nothing to install.
memory_bank_update is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the memory_bank_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_bank_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_bank_update is provided by the Memory Bank Mcp Mongodb MCP server (sato-isolated/memory-bank-mcp-mongo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
