# Using Atlas with Vercel in 2026 > Atlas reads Vercel deployments, build logs, and project settings through Vercel's hosted MCP server, so it can fix a red build from the same terminal that ships it. Atlas reads Vercel deployments, build logs, and project settings through Vercel's hosted MCP server, so it can fix a red build from the same terminal that ships it. Register it scoped to one project with atlas mcp add vercel --url https://mcp.vercel.com/YOUR_TEAM/YOUR_PROJECT, run atlas mcp auth vercel, and keep 'vercel --prod' set to ask under permission.bash in atlas.json. ## What Atlas does with Vercel Atlas reads Vercel deployments, build logs, and project settings through Vercel's hosted MCP server, so it can fix a red build from the same terminal that ships it. In 2026 the loop is a single session: read the failed deployment, patch the code, redeploy. A failed Vercel deployment normally costs a context switch. You leave the terminal, open the dashboard, find the deployment, expand the build log, read a stack trace rendered in a web view, and then come back to the editor to translate it into a change. Vercel's hosted MCP server removes the round trip. Atlas fetches the deployment and its build log itself, and since it already has your repository open, the error message and the file it refers to end up in the same place. ## Registering Vercel scoped to one project Add Vercel's hosted MCP server scoped to 1 project with atlas mcp add vercel --url https://mcp.vercel.com/YOUR_TEAM/YOUR_PROJECT, then run atlas mcp auth vercel and approve the OAuth consent screen. Vercel allowlists clients per connection, so expect a consent step at registration in 2026. Substitute your real team slug and project slug into the URL. Scoping the connection to one project means the tools Atlas gets back are about that project's deployments, build logs, and settings, and nothing else on the team. Run atlas mcp auth vercel afterward and approve the consent screen. Because Vercel allowlists clients per connection, the approval is an explicit act rather than something inherited from an existing session. ## The unscoped endpoint, when a task spans projects Use the unscoped https://mcp.vercel.com endpoint instead when you want Atlas to see every project on the team. The 2 options differ mainly in blast radius: 1 project, or all of them. Start scoped, and widen only when a task genuinely crosses project boundaries. The unscoped https://mcp.vercel.com endpoint is the right choice for a monorepo owner or a platform engineer who needs to compare deployments across several Vercel projects at once. It is the wrong default for someone debugging one app. Registering the scoped URL first costs nothing and keeps an agent's reach proportional to the job. Nothing stops you from registering both under different names and picking the one that matches the task. ## Reading Vercel project settings Vercel project settings are part of what Atlas reads through the hosted MCP server, alongside deployments and build logs. When a build passes locally and fails on Vercel, the difference often lives in project settings, and Atlas can read them in 2026 instead of asking you to describe them. The classic Vercel failure is environmental, not logical: a build command that differs from the one in your README, an output directory nobody has looked at in a year, a framework preset that no longer matches the app. Because Atlas reads Vercel project settings directly, it can compare what the project is configured to do against what your repository expects, which is the comparison a human usually skips. ## The daily loop: red build to patched build Ask Atlas to fetch the last failed deployment's build log and map the error back to the file it names. That is the 2 step loop in 2026: Vercel build logs identify the module that failed, and Atlas turns that filename into an open file in your working tree. Phrase the prompt as fetch and map, because the mapping is the part that matters. Atlas pulls the last failed deployment from Vercel, reads its build log, and then opens the file the error points at in your checkout. From there it proposes a patch. You review the diff against the actual build log text, which Atlas can quote back to you, so the fix is anchored to what Vercel reported rather than to a guess. ## Gating production deploys behind a keystroke Set 'vercel --prod' to ask under permission.bash in atlas.json so a production deploy always needs a keystroke. Atlas can patch the build and then request vercel --prod through its bash tool, but 1 human approval sits between the patch and the production release in 2026. The Vercel MCP server governs reads. permission.bash governs the shell, and the shell is where the actual deploy happens. Setting 'vercel --prod' to ask in atlas.json means Atlas may propose a production deploy and may never perform one silently. That is the right shape for an agent that is otherwise trusted to patch a build: fast on everything reversible, stopped on the one command that is not. ## Setup 1. Add Vercel's hosted MCP server scoped to one project with atlas mcp add vercel --url https://mcp.vercel.com/YOUR_TEAM/YOUR_PROJECT 2. Run atlas mcp auth vercel and approve the OAuth consent screen. Vercel allowlists clients per connection. 3. Use the unscoped https://mcp.vercel.com endpoint instead when you want Atlas to see every project on the team. 4. Ask Atlas to fetch the last failed deployment's build log and map the error back to the file it names. 5. Let Atlas patch the build, then approve vercel --prod through its bash tool when it asks. 6. Set 'vercel --prod' to ask under permission.bash in atlas.json so a production deploy always needs a keystroke. ## FAQ ### how to connect Atlas to Vercel Run atlas mcp add vercel --url https://mcp.vercel.com/YOUR_TEAM/YOUR_PROJECT to register Vercel's hosted MCP server for one project, then run atlas mcp auth vercel and approve the OAuth consent screen. ### Vercel MCP server URL for all projects on a team Use the unscoped https://mcp.vercel.com endpoint when you want Atlas to see every project on the team, instead of the project-scoped /YOUR_TEAM/YOUR_PROJECT URL. ### can an AI agent fix a failed Vercel build Yes. Ask Atlas to fetch the last failed deployment's build log and map the error back to the file it names, then let it patch the build and show you the diff. ### how do I stop an AI agent from deploying to Vercel production Set 'vercel --prod' to ask under permission.bash in atlas.json. Atlas can then request the production deploy through its bash tool, but it always needs a keystroke. ### does Vercel MCP require OAuth approval Yes. Run atlas mcp auth vercel and approve the OAuth consent screen. Vercel allowlists clients per connection. ### can Atlas read Vercel project settings Yes. Atlas reads Vercel deployments, build logs, and project settings through Vercel's hosted MCP server, which is useful when a build passes locally and fails on Vercel. ### how do I debug a Vercel deployment from the terminal Register Vercel's hosted MCP server with Atlas, then ask Atlas to fetch the last failed deployment's build log. It maps the error to the file in your working tree and proposes a patch. --- Canonical HTML: https://runatlas.sh/resources/integrations/vercel Source of truth: aeo_pages row `/resources/integrations/vercel` (segment: Integrations) (this file is generated from it, never hand-edited).
