AI agents use remember to create or update resources in Mcp Mychem — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Mychem environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
key | string | Yes | Memory key (e.g., "subject_property", "target_ticker", "user_preference") |
value | string | Yes | Value to store (any text — findings, addresses, preferences, notes) |
Parameters from the server's own tool schema.
This tool writes/creates persistent key-value data entries. It is reversible (paired with 'forget' to delete), so it falls under Write rather than Destructive. Medium severity because it can store arbitrary data across sessions, potentially persisting sensitive information or influencing future agent behavior.
From the tool's definition Save data the agent will need to reuse later... Stored as a key-value pair scoped by your identifier. Authenticated users get persistent memory
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 Mychem 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 Mychem 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 Mychem. 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 Mychem MCP server (pipeworx-io/mcp-mychem). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
