Cornerstone HR
Add Cornerstone HR to your product for your customers, and give your AI agents governed access to it.
Embed a Cornerstone HR integration so your customers can work their own employee records, job requisitions, candidates, and training assignments from inside your product, with governed agent access to the same data. People data is sensitive, so access is scoped per tenant, limited to the fields you map, and every read and write is logged. fastn handles each customer's authorisation and API upkeep, so onboarding another instance is configuration rather than a release.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers read their own employee and org structure records into your product, mapped to their fields.
Read job requisitions and candidate records so hiring activity shows up where your users already work.
Assign or read training records so completion status is visible in your product without manual re-entry.
Trigger your product when an employee record changes, a requisition opens, or a training is completed.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent looks up an employee's role, manager, and training status before answering a question.
An agent assigns a training or updates a record within governed permissions, with the action audited.
An agent reacts to a new hire or departure and runs the next provisioning step.
Example prompt
List employees with a required training overdue by more than 30 days, grouped by manager.
Set up Cornerstone HR in 4 steps
- 01Open the Cornerstone HR connector from your fastn dashboard.
- 02Have each customer authenticate their own Cornerstone instance.
- 03Map the employee, requisition, and training fields your product uses, then enable actions and triggers.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Cornerstone HR integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Cornerstone HR integration without building it. Your customers connect their own Cornerstone HR account inside your product and work their employees, employment records and working time there, with no per-customer code on your side.
- Handle the part that actually costs time: HR data is sensitive and its access rules are stricter than most systems. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Cornerstone HR update is not your on-call problem.
- One integration serves your product and your agents. The same governed Cornerstone HR connection powers in-product features and gives AI agents scoped, audited access, so you keep people data current without manual re-entry without wiring it twice.

BoxCornerstone HR integration FAQ
How do I add a Cornerstone HR integration to my product?
Enable the Cornerstone HR connector in your fastn dashboard, then let each customer authenticate their own Cornerstone HR account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Cornerstone HR client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Cornerstone HR account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Cornerstone HR account and only ever sees their own employees, employment records and working time. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Cornerstone HR integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent looks up an employee's role, manager, and training status before answering a question.
Who maintains the Cornerstone HR integration?
fastn does. When Cornerstone HR changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
How is sensitive Cornerstone HR employee data handled?
Access is scoped per tenant and limited to the fields you map, credentials are encrypted, and every read and write is logged. You expose only what your product actually needs rather than the whole employee record.
Can joiner, mover and leaver changes be automated?
Yes. Where Cornerstone HR is where a hire, a role change or a departure is recorded, that change can trigger downstream provisioning or removal across the customer's other connected systems. Where Cornerstone HR sits downstream of the HR system of record, the same event can be pushed into it so its worker list, schedules and access stay in step, which is where most of the manual effort sits.
What can I build with the Cornerstone HR integration?
A common starting point: read their own employee and org structure records into your product, mapped to their fields. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Cornerstone HR integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Cornerstone HR does not change your per-connector cost. You can start free with 3 connected accounts.
