What invite_user does on Portkey Admin
AI agents use invite_user to create or update resources in Portkey Admin, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Portkey Admin environment.
Why invite_user is rated Medium
This tool creates user invitations and provisions access credentials (API keys), which are reversible write operations. While it affects security and access control (hence 'high' severity for potential misuse), it does not execute arbitrary code, delete data, or move money.
From the tool's definition Tool description states it will 'Invite a new org user and optionally provision workspace access and an API key in one call.' The words 'invite', 'provision', and 'create' (implicit for API key) indicate data creation and modification operations.
Attacks that exploit this kind of access
The rule that runs invite_user safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Portkey Admin, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For invite_user, this is the rule to start with:
invite_user 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 Portkey Admin, apply this rule, and every invite_user call is checked against it from then on.
Questions about invite_user
Invite a new org user and optionally provision workspace access and an API key in one call. Workspace assignments apply only after acceptance; use add_workspace_member or update_workspace_member later for follow-up changes. It is categorised as a Write tool in the Portkey Admin MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Portkey Admin MCP server in PolicyLayer and add a rule for invite_user: 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 Portkey Admin. Nothing to install.
invite_user 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 invite_user 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 invite_user. 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.
invite_user is provided by the Portkey Admin MCP server (codeswhat/portkey-admin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
