Load the full content of a knowledge module by its exact name/slug. Returns the complete module text (typically 2,000-20,000 words) with code examples, best practices, and references.

AI agents call absorb to retrieve information from Celiums Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only data retrieval from a knowledge base. It fetches and returns existing module content without any side effects, state changes, or irreversible operations. The severity is low because retrieval of knowledge modules poses minimal risk even if misused by an AI agent—there are no destructive, financial, or execution-based consequences.
From the tool's definition Tool description states 'Load the full content of a knowledge module' and 'returns the complete module text'. The verb 'Load' and 'returns' indicate retrieval without modification. No creation, deletion, code execution, or financial operations are mentioned.
Documented attack patterns abuse exactly the kind of access absorb 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 absorb:
{
"version": "1",
"default": "deny",
"tools": {
"absorb": {}
}
}absorb is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Load the full content of a knowledge module by its exact name/slug. Returns the complete module text (typically 2,000-20,000 words) with code examples, best practices, and references. Use after forage to read a specific module in full. Behavior: looks up the module by slug, returns full markdown content. If not found, suggests using forage to search. Example: absorb(. It is categorised as a Read tool in the Celiums Memory MCP Server, which means it retrieves data without modifying state.
Register the Celiums Memory MCP server in PolicyLayer and add a rule for absorb: 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.
absorb is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the absorb 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 absorb. 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.
absorb 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.
