AI agents use remember to create or update resources in Mcp Merriam Webster — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Merriam Webster environment.
| Parameter | Type | Required | Description |

Parameters from the server's own tool schema.
This tool writes/creates persistent key-value data in a memory store. It has side effects (storing data that persists across sessions) but is reversible since a paired 'forget' tool exists to delete entries. This makes it a Write operation. Misuse could involve storing sensitive or malicious data persistently, giving it a medium severity.
From the tool's definition Save data the agent will need to reuse later — across this conversation or across sessions. Stored as a key-value pair scoped by your identifier.
Attacks that exploit this kind of access
Save data the agent will need to reuse later — across this conversation or across sessions. Use when you discover something worth carrying forward (a resolved ticker, a target address, a user preference, a research subject) so you don't have to look it up again. Stored as a key-value pair scoped by your identifier. Authenticated users get persistent memory; anonymous sessions retain memory for 24 hours. Pair with recall to retrieve later, forget to delete. It is categorised as a Write tool in the Mcp Merriam Webster MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
remember accepts 2 parameters: key, value. Required: key, value. The full parameter table on this page comes from the server's own tool schema.
Register the Mcp Merriam Webster 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 Mcp Merriam Webster. Nothing to install.
remember 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 remember 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 remember. 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.
remember is provided by the Mcp Merriam Webster MCP server (https://gateway.pipeworx.io/merriam-webster/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
