create_entities
Create multiple new entities in the knowledge graph
Part of the Memory MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents use create_entities to create or modify resources in Memory. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
WHY ENFORCE A POLICY ON CREATE_ENTITIES
Without a policy, an AI agent could call create_entities repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Memory.
RECOMMENDED POLICY
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

FREQUENTLY ASKED QUESTIONS
What does the create_entities tool do?
Create multiple new entities in the knowledge graph. It is categorised as a Write tool in the Memory 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_entities?
Add a rule in your Intercept YAML policy under the tools section for create_entities. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Memory MCP server.
What risk level is create_entities?
create_entities is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Can I rate-limit create_entities?
Yes. Add a rate_limit block to the create_entities rule in your Intercept 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_entities completely?
Set action: deny in the Intercept policy for create_entities. 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_entities?
create_entities is provided by the Memory MCP server (modelcontextprotocol/server-memory). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
