Vercel
Add Vercel to your product for your customers, and give your AI agents governed access to it.
A Vercel integration gives your product visibility and control over how a customer ships: projects, their deployments and build state, build logs, environment variables, and the domains and aliases pointing at them. Two details decide whether it works. Nearly every call needs the team id when a project belongs to a team rather than a personal account, and omitting it quietly looks in the wrong place. Environment variables are scoped by target, so production, preview and development each hold their own value, and a preview value can be narrowed further to a git branch, which makes setting a variable ambiguous unless its target is named. Deployments are immutable, and promoting one is an alias change. fastn handles tokens, team scoping and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let a customer connect their own team so your product reads their projects and deployments without a shared token.
Set an environment variable against the right target, since production, preview and development hold separate values.
Show build state and logs for a deployment inside your product, so a failure is diagnosed where it was noticed.
Manage domains and aliases, treating a promotion as the alias change it really is rather than a fresh build.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reports which deployments failed for one team and what the build log says about each.
An agent updates an environment variable for a named target within scoped permissions, and the change is logged.
An agent checks which deployment a domain currently points at before anybody changes it.
Example prompt
Which deployments on this project failed today, and what environment variables differ between preview and production?
Set up Vercel in 4 steps
- 01Enable the Vercel connector from your fastn dashboard.
- 02Have each customer authorise their own Vercel account, so calls run under their credentials rather than a shared key.
- 03Decide which services, builds and deployments your product needs, map those fields, then enable the actions and triggers you want.
- 04Call it from your product and expose it to your agents through the same governed connection.
Why teams use the Vercel integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Vercel integration without building it. Your customers connect their own Vercel account inside your product and work their services, builds and deployments there, with no per-customer code on your side.
- Handle the part that actually costs time: these systems emit a lot of webhooks, and replay after downtime has to be handled. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Vercel update is not your on-call problem.
- One integration serves your product and your agents. The same governed Vercel connection powers in-product features and gives AI agents scoped, audited access, so you connect engineering activity to the rest of the business without wiring it twice.

PostgreSQLVercel integration FAQ
How do I add a Vercel integration to my product?
Enable the Vercel connector in your fastn dashboard, then let each customer authenticate their own Vercel account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Vercel client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Vercel account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Vercel account and only ever sees their own services, builds and deployments. 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 Vercel 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 reports which deployments failed for one team and what the build log says about each.
Who maintains the Vercel integration?
fastn does. When Vercel 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.
Can I react to Vercel events in real time?
Yes, through event triggers. Events are delivered per tenant and can be replayed after an outage, so a webhook missed during downtime is not silently lost.
Can an agent open or update items in Vercel?
Yes, within scoped permissions, and every action is audited so an agent's changes are attributable.
What can I build with the Vercel integration?
A common starting point: let a customer connect their own team so your product reads their projects and deployments without a shared token. 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 Vercel integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Vercel does not change your per-connector cost. You can start free with 3 connected accounts.
