create_identity · Infisical MCP: Risk & Policy

WHAT IT DOES

What create_identity does on Infisical MCP

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

WHY IT NEEDS A POLICY

Why create_identity needs a policy

This tool creates a new machine identity within the organization, which modifies system state by adding an authenticable entity. This is a Write operation because it creates new data reversibly (the identity can be deleted or modified later).

From the tool's definition Tool name 'create_identity' and description 'Create an organization machine identity' indicate a creation operation that adds a new identity object to the system.

create_identity Rate-limited

create_identity 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.

FAQ

Questions about create_identity

What does the create_identity tool do? +

Create an organization machine identity. It is categorised as a Write tool in the Infisical MCP 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_identity? +

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

What risk level is create_identity? +

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

Can I rate-limit create_identity? +

Yes. Add a rate_limit block to the create_identity 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_identity completely? +

Set action: deny in the PolicyLayer policy for create_identity. 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_identity? +

create_identity is provided by the Infisical MCP server (plgonzalezrx8/infisicalmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
