Ship and inspect Vercel deployments — projects, aliases, env vars, domains and logs.
Vercel ships in the w6w first-party pack. It declares 28 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.vercelVercel deploys and hosts sites and functions, and this app ships and inspects deployments without leaving the workflow. Trigger a deployment from a Git source, watch its build logs, cancel it while it’s still building, or promote and roll back which deployment serves production traffic. Build logs and runtime logs are read separately, since one is what the build printed and the other is what the deployed functions log while serving requests.
Beyond deployments, it manages the surrounding project config: environment variables (encrypted by default, redacted unless decryption is explicitly requested), domains and the aliases that point them at a specific deployment, and project settings like framework and build command. Team scope is set once on the connection rather than repeated per action, with a per-call override for a token that spans several teams.
Good for triggering a deploy from an external event, rolling back production the moment an error rate spikes, or keeping environment variables and domains in sync as part of an infrastructure workflow — the deployment operations a developer would otherwise run from the Vercel dashboard or CLI.
Three routes to the same 28 actions. The Workflow tab is generated from Vercel's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
deployment-alias-list List the aliases currently pointing at one deployment.
deployment-event-list Read the build events (logs) a deployment produced.
deployment-list List deployments, optionally filtered by project, state, target, branch or SHA.
deployment-promote Make an existing deployment the project's production deployment.
deployment-rollback Roll a project's production back to an earlier deployment.
env-update Change an existing environment variable's value, targets, or type.
project-domain-add Attach a domain to a project, optionally as a branch domain or a redirect.
runtime-log-list Read the runtime (function) logs for one deployment of a project.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying Vercel's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for Vercel, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to Vercel. The Workflow tab is where this app's
real ids are.

One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.vercel#alias-assign",
"input": {
"deploymentId": "<deploymentId>",
"alias": "<alias>"
}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's Vercel connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
Vercel's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. Vercel itself is MIT, and the runtime that executes it is source-available (FSL).
Vercel declares its own checks, so its health is a property of the app rather than something the host guesses at.
