Secure Vercel access for AI agents
Manage Vercel projects, deployments, domains, and agent runs, search Vercel docs, and read/reply to Toolbar comment threads, using Vercel's official MCP server
Through Vercel, agents can inspect projects and deployments, read build and runtime logs, trigger deploys, check domains, and work with Toolbar comment threads — every call runs through your policies and is logged for audit.
Server URL: https://mcp.vercel.com
Setup
- Navigate to Resources and click Add Resource
- Select Vercel from the catalog
- Provide your Vercel custom OAuth app credentials (see Bring your own app)
- Click Add
Each user connects their own Vercel account via OAuth when they first use a Vercel tool. Vercel's own team and project-level permissions control what each user can reach — the gateway does not widen access beyond what the authenticated user could already do in Vercel. Navigate to Connections to manage linked accounts.
Credential modes
Vercel supports one mode:
- Bring your own app: a custom OAuth app owned by your organization, registered through Vercel's integration console. This MCP server does not support dynamic client registration.
See Credential modes for the full comparison.
Bring your own app
A Vercel administrator registers a custom OAuth app (Account Settings → Integrations → Create Integration, OAuth2 authentication), then returns to SecureAuth with the Client ID and Client Secret.
In the Agent Authority console, go to Resources → Add Resource → Vercel → Bring your own app and copy the redirect URI shown on the page.
In the Vercel integration console, on the app's OAuth configuration:
- Add the redirect URI you copied to the list of allowed redirect URIs; it must use HTTPS
- Ensure the
openid,email,profile, andoffline_accessscopes are enabled - Copy the Client ID and Client Secret
Paste both back into the Vercel configure page in the Agent Authority console, then click Add. Leave Token Endpoint Authentication on Auto-detect — Vercel works with the detected default.
Authorization goes through Vercel's global OAuth gateway (vercel.com / api.vercel.com) — the same endpoints for every Vercel account, with no per-org configuration needed.

Policy examples
Rules are evaluated top to bottom and the first match wins. Deny rules only bite when they sit above whatever would otherwise allow the call — including the seeded Allow all rule every org starts with — and allow rules on their own restrict nothing. New rules are inserted at the top of the list, so create them in reverse order or drag them into place. See Policies.
- Read-only access. Deny
deploy_to_vercel,import-claude-design-from-url,get_access_to_vercel_url,change_toolbar_thread_resolve_status,reply_to_toolbar_thread,edit_toolbar_message, andadd_toolbar_reaction.import-claude-design-from-urlwrites a design into your Vercel account, andget_access_to_vercel_urlmints a link that bypasses authentication on protected deployments — both are easy to miss when scanning for obvious write verbs. - Deployment visibility without deploys. Allow
list_projects,get_project,list_deployments,get_deployment,get_deployment_build_logs,get_runtime_logs, andget_runtime_errors, then deny*below them so nothing else on Vercel falls through to Allow all. - Block Toolbar write actions. Deny
change_toolbar_thread_resolve_status,reply_to_toolbar_thread,edit_toolbar_message, andadd_toolbar_reaction.
