WHAT IT DOES

What create_concept does on MegaMemory

AI agents use create_concept to create or update resources in MegaMemory, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MegaMemory environment.

RISK

Why create_concept is rated Medium

This tool creates new data entries in a persistent knowledge graph, which is a Write operation. It is reversible (concepts can be removed via remove_concept sibling tool).

From the tool's definition Tool description explicitly states 'Add a new concept to the knowledge graph' and instructs to 'record new features, components, patterns, or decisions.' This creates and adds data reversibly to a persistent knowledge structure.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_concept safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MegaMemory, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_concept, this is the rule to start with:

create_concept Rate-limited

create_concept 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.

The button opens the PolicyLayer dashboard: create your workspace, connect MegaMemory, apply this rule, and every create_concept call is checked against it from then on.

FAQ

Questions about create_concept

What does the create_concept tool do? +

Add a new concept to the knowledge graph. Call this after completing a task to record new features, components, patterns, or decisions you built. Include specific details: parameter names, defaults, file locations, and rationale. It is categorised as a Write tool in the MegaMemory MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_concept? +

Register the MegaMemory MCP server in PolicyLayer and add a rule for create_concept: 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 MegaMemory. Nothing to install.

What risk level is create_concept? +

create_concept is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_concept? +

Yes. Add a rate_limit block to the create_concept 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.

How do I block create_concept completely? +

Set action: deny in the PolicyLayer policy for create_concept. 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.

What MCP server provides create_concept? +

create_concept is provided by the MegaMemory MCP server (0xk3vin/megamemory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
