WHAT IT DOES

What invite_workspace_user does on Sanka MCP Server

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

RISK

Why invite_workspace_user is rated Medium

This tool creates a new workspace user invitation and potentially allocates a billable resource (seat). While it has financial implications (consuming a billable seat), the primary action is creating/modifying user access, which is characteristic of Write.

From the tool's definition The tool description explicitly states it 'Invite one user to an explicitly verified Sanka workspace' and 'sends an invitation email and may consume a billable seat'.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs invite_workspace_user safely

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

invite_workspace_user Rate-limited

invite_workspace_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.

FAQ

Questions about invite_workspace_user

What does the invite_workspace_user tool do? +

Invite one user to an explicitly verified Sanka workspace. Call current_workspace immediately before this tool and pass its internal workspace_id as expected_workspace_id. The tool and API both block on a mismatch. This sends an invitation email and may consume a billable seat, so explicit confirmation is required. It is categorised as a Write tool in the Sanka MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on invite_workspace_user? +

Register the Sanka MCP Server MCP server in PolicyLayer and add a rule for invite_workspace_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 Sanka MCP Server. Nothing to install.

What risk level is invite_workspace_user? +

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

Can I rate-limit invite_workspace_user? +

Yes. Add a rate_limit block to the invite_workspace_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.

How do I block invite_workspace_user completely? +

Set action: deny in the PolicyLayer policy for invite_workspace_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.

What MCP server provides invite_workspace_user? +
