Productivity integration · Beta
Evaluate the Justworks MCP server for your MSP stack.
The Stackyapper Justworks connection is available for evaluation. Beta apps may change and should begin with a small set of read-only tools.
What is the Stackyapper Justworks MCP integration?
The Stackyapper Justworks integration lets compatible AI clients use approved Justworks tools without receiving the provider credential.
What can the Justworks integration do?
PEO and HR platform for company profile, employee roster, payrolls, paystubs, deductions, and time off. An admin registers the Justworks-issued OAuth application, then authorizes one company grant for this workspace.
Available tools depend on the provider account, workspace settings, and the signed-in user’s permissions.
Who is the Justworks MCP integration for?
It is for MSP and customer teams that need approved Justworks context available to an AI assistant while keeping provider authorization inside the selected Stackyapper workspace.

How is Justworks access controlled?
- An administrator connects Justworks in the intended Stackyapper workspace.
- The administrator grants available tools to specific workspaces, groups, or people.
- Stackyapper resolves the connection within the current credential and tenant scope.
- Stackyapper checks permissions and safety controls again before every request.
- Actions that require confirmation do not execute until the exact request is confirmed.
Does Justworks send its API credential to Claude or ChatGPT?
No. Stackyapper keeps the encrypted provider credential secure and does not send it to the AI client.
How do I evaluate the Justworks beta?
- Create or select a non-production Stackyapper workspace.
- Find Justworks in the app catalog and request beta access if it is not enabled.
- Use the provider authorization described above with the narrowest practical permissions.
- Grant only the read-only tool needed for the evaluation.
- Request no more than five records, confirm the result in Audit, and expand access only when the test succeeds.
Support boundaries
- Stackyapper does not claim that every endpoint in the Justworks API is exposed.
- Provider plan, account configuration, API scopes, and upstream availability can limit results.
- Administrators are responsible for correct provider permissions and user grants.
- Support status and available tools can change as provider capabilities evolve.
