# ai agent for vercel: read the build log, deploy again

a failed deployment is a log file and a guess. connecting vercel to a room removes the guess, because the agent that reads the build log also has the repository checked out on the room's own server and can reproduce the build there.

## reading the deployment

`vercel_list_projects` and `vercel_get_project` describe a project with its framework and latest deployment. `vercel_list_deployments` filters by project, state, or target, `vercel_get_deployment` reads one by id or hostname with its state and urls, and `vercel_get_deployment_build_logs` reads the build log events, optionally errors only. that last one is the tool that matters: it goes to the failing line rather than summarising the run.

## acting on it

`vercel_deploy` creates a preview or production deployment from inline files. it sits behind the create deployments scope, which is off by default, because a production deployment replaces live traffic the moment the build passes. with the scope on it still asks for your approval before each call. `vercel_list_teams` confirms which account the room is pointed at, and `vercel_get_granted_scopes` lets an agent check what it holds before it offers to ship anything.

## reacting rather than polling

`vercel_subscribe` attaches an agent to a project or the connected team. deployment created, succeeded, errored and canceled events wake it in the chat where it subscribed, along with project and domain events, so the investigation starts while the build output is still fresh.

## example tasks

- **the last deploy failed. work out why and fix it.**

  the agent reads the errors from the build log, reproduces the build on the room server, writes the fix, and opens a pull request with the change.

  tools: `vercel_list_deployments` -> `vercel_get_deployment_build_logs` -> `bash` -> `github_create_pull_request`

- **which of our projects has not deployed in the last month?**

  it lists the projects, reads each one's latest deployment, and reports the stale ones with dates rather than a vague impression.

  tools: `vercel_list_projects` -> `vercel_get_project` -> `vercel_list_deployments`

- **watch production and tell me the moment a deployment errors.**

  the project subscription wakes the agent in this chat on the deployment event, and it pulls the error lines from the build log before reporting.

  tools: `vercel_subscribe` -> `vercel_get_deployment` -> `vercel_get_deployment_build_logs`

## what it will not do

an agent cannot change environment variables, manage domains, edit project settings, or roll back a deployment. it reaches one vercel account, the one the room connected, and with the deploy scope off it can read everything and change nothing.

## faq

### can an ai agent read my vercel build logs?

yes. vercel_get_deployment_build_logs reads a deployment's build log events, optionally errors only, so an agent can go straight to the line that failed instead of asking you to paste it. that is a read tool, so it runs without asking.

### can an agent deploy to production?

vercel_deploy sits behind the create deployments scope, which is off by default because a production deployment replaces live traffic once the build passes. turn it on and the call still stops for your approval before it runs.

### which vercel account does the room reach?

exactly one. vercel_list_teams reads the single team or account the room is connected to, and vercel_list_projects lists that account's projects. connecting vercel in one room gives no other room access to it.

### how does an agent know a deployment failed?

vercel_subscribe attaches it to a project or the connected team. deployment created, succeeded, errored and canceled events, plus project and domain events, wake the agent in the chat where it subscribed, so a failed build can be investigated immediately.

### what can it do with read access alone?

list projects and deployments, read one deployment by id or hostname with its state and urls, read a project with its framework and latest deployment, and read build logs. that covers the whole diagnosis path without any ability to change what is live.
