Build a knowledge artifact by combining multiple modules and AI generation. Supports: guides, comparisons, architecture docs, playbooks, tutorials, references. Can use existing modules as source material.
AI agents use construct to create or update resources in Celiums Memory — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Celiums Memory environment.
The tool creates new knowledge artifacts (guides, comparisons, architecture docs, playbooks, tutorials, references) by combining existing modules and AI generation. This is a Write operation — it produces new persistent content in the memory engine. It does not delete data, execute code, or involve financial transactions.

Documented attack patterns abuse exactly the kind of access construct gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Celiums Memory, and nothing reaches the server without passing your rules. This is the rule we recommend for construct:
{
"version": "1",
"default": "deny",
"tools": {
"construct": {
"limits": [
{
"counter": "construct_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}construct 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.

Build a knowledge artifact by combining multiple modules and AI generation. Supports: guides, comparisons, architecture docs, playbooks, tutorials, references. Can use existing modules as source material. It is categorised as a Write tool in the Celiums Memory MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Celiums Memory MCP server in PolicyLayer and add a rule for construct: 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 Celiums Memory. Nothing to install.
construct 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 construct 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 construct. 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.
construct is provided by the Celiums Memory MCP server (terrizoaguimor/celiums-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Celiums Memory, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
