@vercel/sdk

The @vercel/sdk is a type-safe Typescript SDK that gives you full control over the entire Vercel platform through the Vercel REST API.

Table of Contents

SDK Installation

The SDK can be installed with either npm, pnpm, bun or yarn package managers.

NPM

npm add @vercel/sdk

PNPM

pnpm add @vercel/sdk

Bun

bun add @vercel/sdk

Yarn

yarn add @vercel/sdk zod

# Note that Yarn does not install peer dependencies automatically. You will need
# to install zod as shown above.

Note

This package is published as an ES Module (ESM) only. For applications using CommonJS, use await import("@vercel/sdk") to import and use this package.

Model Context Protocol (MCP) Server

This SDK is also an installable MCP server where the various SDK methods are exposed as tools that can be invoked by AI applications.

Node.js v20 or greater is required to run the MCP server from npm.

Claude installation steps

Add the following server definition to your claude_desktop_config.json file:

{
  "mcpServers": {
    "Vercel": {
      "command": "npx",
      "args": [
        "-y", "--package", "@vercel/sdk",
        "--",
        "mcp", "start",
        "--bearer-token", "..."
      ]
    }
  }
}
Cursor installation steps

Create a .cursor/mcp.json file in your project root with the following content:

{
  "mcpServers": {
    "Vercel": {
      "command": "npx",
      "args": [
        "-y", "--package", "@vercel/sdk",
        "--",
        "mcp", "start",
        "--bearer-token", "..."
      ]
    }
  }
}

You can also run MCP servers as a standalone binary with no additional dependencies. You must pull these binaries from available Github releases:

curl -L -o mcp-server \
    https://github.com/{org}/{repo}/releases/download/{tag}/mcp-server-bun-darwin-arm64 && \
chmod +x mcp-server

If the repo is a private repo you must add your Github PAT to download a release -H "Authorization: Bearer {GITHUB_PAT}".

{
  "mcpServers": {
    "Todos": {
      "command": "./DOWNLOAD/PATH/mcp-server",
      "args": [
        "start"
      ]
    }
  }
}

For a full list of server arguments, run:

npx -y --package @vercel/sdk -- mcp start --help

Requirements

For supported JavaScript runtimes, please consult RUNTIMES.md.

Access Tokens

You need to pass a valid access token to be able to use any resource or operation. Refer to Creating an Access Token to learn how to create one. Make sure that you create a token with the correct Vercel scope. If you face permission (403) errors when you are already sending a token, it can be one of the following problems:

  • The token you are using has expired. Check the expiry date of the token in the Vercel dashboard.
  • The token does not have access to the correct scope, either not the right team or it does not have account level access.
  • The resource or operation you are trying to use is not available for that team. For example, AccessGroups is an Enterprise only feature and you are using a token for a team on the pro plan.

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name Type Scheme
bearerToken http HTTP Bearer

To authenticate with the API the bearerToken parameter must be set when initializing the SDK client instance. For example:

import { Vercel } from "@vercel/sdk";

const vercel = new Vercel({
  bearerToken: "<YOUR_BEARER_TOKEN_HERE>",
});

async function run() {
  const result = await vercel.postDomains({
    name: "example.com",
    method: "transfer-in",
    token: "fdhfr820ad#@FAdlj$$",
  });

  console.log(result);
}

run();

SDK Example Usage

List deployments

List deployments under the authenticated user or team.

import { Vercel } from "@vercel/sdk";

const vercel = new Vercel({
  bearerToken: "<YOUR_BEARER_TOKEN_HERE>",
});

async function run() {
  const result = await vercel.deployments.getDeployments({
    app: "docs",
    from: 1612948664566,

Standalone functions

All the methods listed above are available as standalone functions. These functions are ideal for use in applications running in the browser, serverless runtimes or other environments where application bundle size is a primary concern. When using a bundler to build your application, all unused functionality will be either excluded from the final bundle or tree-shaken away.

To read more about standalone functions, check FUNCTIONS.md.

Available standalone functions

File uploads

Certain SDK methods accept files as part of a multi-part request. It is possible and typically recommended to upload files as a stream rather than reading the entire contents into memory. This avoids excessive memory consumption and potentially crashing with out-of-memory errors when working with very large files. The following example demonstrates how to attach a file stream to a request.

Tip

Depending on your JavaScript runtime, there are convenient utilities that return a handle to a file without reading the entire contents into memory:

  • Node.js v20+: Since v20, Node.js comes with a native openAsBlob function in node:fs.
  • Bun: The native Bun.file function produces a file handle that can be used for streaming file uploads.
  • Browsers: All supported browsers return an instance to a File when reading the value from an <input type="file"> element.
  • Node.js v18: A file stream can be created using the fileFrom helper from fetch-blob/from.js.
import { Vercel } from "@vercel/sdk";
import { openAsBlob } from "node:fs";

const vercel = new Vercel({
  bearerToken: "<YOUR_BEARER_TOKEN_HERE>",
});

async function run() {
  const result = await vercel.artifacts.uploadArtifact({
    contentLength: 3848.22,
    xArtifactDuration: 400,
    xArtifactClientCi: "VERCEL",
    xArtifactClientInteractive: 0,
    xArtifactTag: "Tc0BmHvJYMIYJ62/zx87YqO0Flxk+5Ovip25NY825CQ=",
    hash: "12HKQaOmR5t5Uy6vdcQsNIiZgHGB",
    teamId: "team_1a2b3c4d5e6f7g8h9i0j1k2l",
    slug: "my-team-url-slug",
    requestBody: await openAsBlob("example.file"),
  });

  console.log(result);
}

run();

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a retryConfig object to the call:

import { Vercel } from "@vercel/sdk";

const vercel = new Vercel();

async function run() {
  const result = await vercel.postDomains({
    name: "example.com",
    method: "transfer-in",
    token: "fdhfr820ad#@FAdlj$$",
  }, {
    retries: {
      strategy: "backoff",
      backoff: {
        initialInterval: 1,
        maxInterval: 50,
        exponent: 1.1,
        maxElapsedTime: 100,
      },
      retryConnectionErrors: false,
    },
  });

  console.log(result);
}

run();

If you'd like to override the default retry strategy for all operations that support retries, you can provide a retryConfig at SDK initialization:

import { Vercel } from "@vercel/sdk";

const vercel = new Vercel({
  retryConfig: {
    strategy: "backoff",
    backoff: {
      initialInterval: 1,
      maxInterval: 50,
      exponent: 1.1,
      maxElapsedTime: 100,
    },
    retryConnectionErrors: false,
  },
});

async function run() {
  const result = await vercel.postDomains({
    name: "example.com",
    method: "transfer-in",
    token: "fdhfr820ad#@FAdlj$$",
  });

  console.log(result);
}

run();

Error Handling

VercelError is the base class for all HTTP error responses. It has the following properties:

Property Type Description
error.message string Error message
error.statusCode number HTTP response status code eg 404
error.headers Headers HTTP response headers
error.body string HTTP body. Can be empty string if no body is returned.
error.rawResponse Response Raw HTTP response
error.data$ Optional. Some errors may contain structured data. See Error Classes.

Example

import { Vercel } from "@vercel/sdk";
import { VercelBadRequestError } from "@vercel/sdk/models/vercelbadrequesterror.js";
import { VercelError } from "@vercel/sdk/models/vercelerror.js.js";

const vercel = new Vercel();

async function run() {
  try {
    const result = await vercel.postDomains({
      name: "example.com",
      method: "transfer-in",
      token: "fdhfr820ad#@FAdlj$$",
    });

    console.log(result);
  } catch (error) {
    // The base class for HTTP error responses
    if (error instanceof VercelError) {
      console.log(error.message);
      console.log(error.statusCode);
      console.log(error.body);
      console.log(error.headers);

      // Depending on the method different errors may be thrown
      if (error instanceof VercelBadRequestError) {
        console.log(error.data$.error); // models.ErrorT
      }
    }
  }
}

run();

Error Classes

Primary errors:

Less common errors (8)

Network errors:

Inherit from VercelError:

  • VercelNotFoundError: Status code 404. Applicable to 100 of 174 methods.*
  • VercelRateLimitError: . Status code 429. Applicable to 1 of 174 methods.*
  • ResponseValidationError: Type mismatch between the data returned from the server and the structure expected by the SDK. See error.rawValue for the raw value and error.pretty() for a nicely formatted multi-line string.

* Check the method documentation to see if the error is applicable.

Server Selection

Override Server URL Per-Client

The default server can be overridden globally by passing a URL to the serverURL: string optional parameter when initializing the SDK client instance. For example:

import { Vercel } from "@vercel/sdk";

const vercel = new Vercel({
  serverURL: "https://api.vercel.com",
});

async function run() {
  const result = await vercel.postDomains({
    name: "example.com",
    method: "transfer-in",
    token: "fdhfr820ad#@FAdlj$$",
  });

  console.log(result);
}

run();

Custom HTTP Client

The TypeScript SDK makes API calls using an HTTPClient that wraps the native Fetch API. This client is a thin wrapper around fetch and provides the ability to attach hooks around the request lifecycle that can be used to modify the request or handle errors and response.

The HTTPClient constructor takes an optional fetcher argument that can be used to integrate a third-party HTTP client or when writing tests to mock out the HTTP client and feed in fixtures.

The following example shows how to use the "beforeRequest" hook to to add a custom header and a timeout to requests and how to use the "requestError" hook to log errors:

import { Vercel } from "@vercel/sdk";
import { HTTPClient } from "@vercel/sdk/lib/http";

const httpClient = new HTTPClient({
  // fetcher takes a function that has the same signature as native `fetch`.
  fetcher: (request) => {
    return fetch(request);
  }
});

httpClient.addHook("beforeRequest", (request) => {
  const nextRequest = new Request(request, {
    signal: request.signal || AbortSignal.timeout(5000)
  });

  nextRequest.headers.set("x-custom-header", "custom value");

  return nextRequest;
});

httpClient.addHook("requestError", (error, request) => {
  console.group("Request Error");
  console.log("Reason:", `${error}`);
  console.log("Endpoint:", `${request.method} ${request.url}`);
  console.groupEnd();
});

const sdk = new Vercel({ httpClient });

Debugging

You can setup your SDK to emit debug logs for SDK requests and responses.

You can pass a logger that matches console's interface as an SDK option.

Warning

Beware that debug logging will reveal secrets, like API tokens in headers, in log messages printed to a console or files. It's recommended to use this feature only during local development and not in production.

import { Vercel } from "@vercel/sdk";

const sdk = new Vercel({ debugLogger: console });

Development

Maturity

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

Contributions

While we value open-source contributions to this SDK, this library is generated programmatically. Any manual changes added to internal files will be overwritten on the next generation. We look forward to hearing your feedback. Feel free to open a PR or an issue with a proof of concept and we'll do our best to include it in a future release.
