Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

SDK Installation

[!TIP] To finish publishing your SDK to npm and others you must run your first generation action.

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

NPM

npm add <UNSET>

PNPM

pnpm add <UNSET>

Bun

bun add <UNSET>

Yarn

yarn add <UNSET> zod

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

[!NOTE] This package is published with CommonJS and ES Modules (ESM) support.

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.

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

{
  "mcpServers": {
    "RaribleProtocolMcp": {
      "command": "npx",
      "args": [
        "-y", "--package", "sei-mcp",
        "--",
        "mcp", "start",
        "--api-key-auth", "..."
      ]
    }
  }
}

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

{
  "mcpServers": {
    "RaribleProtocolMcp": {
      "command": "npx",
      "args": [
        "-y", "--package", "sei-mcp",
        "--",
        "mcp", "start",
        "--api-key-auth", "..."
      ]
    }
  }
}

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 sei-mcp -- mcp start --help

Requirements

For supported JavaScript runtimes, please consult RUNTIMES.md.

SDK Example Usage

Example

import { RaribleProtocolMcp } from "sei-mcp";

const raribleProtocolMcp = new RaribleProtocolMcp({
  apiKeyAuth: process.env["RARIBLEPROTOCOLMCP_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await raribleProtocolMcp.nftItems.getItemById({
    itemId:
      "ETHEREUM:0xb66a603f4cfe17e3d27b87a8bfcad319856518b8:32292934596187112148346015918544186536963932779440027682601542850818403729410",
  });

  // Handle the result
  console.log(result);
}

run();

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

| Name | Type | Scheme | Environment Variable | | ------------ | ------ | ------- | --------------------------------- | | apiKeyAuth | apiKey | API key | RARIBLEPROTOCOLMCP_API_KEY_AUTH |

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

import { RaribleProtocolMcp } from "sei-mcp";

const raribleProtocolMcp = new RaribleProtocolMcp({
  apiKeyAuth: process.env["RARIBLEPROTOCOLMCP_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await raribleProtocolMcp.nftItems.getItemById({
    itemId:
      "ETHEREUM:0xb66a603f4cfe17e3d27b87a8bfcad319856518b8:32292934596187112148346015918544186536963932779440027682601542850818403729410",
  });

  // Handle the result
  console.log(result);
}

run();

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.

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 { RaribleProtocolMcp } from "sei-mcp";

const raribleProtocolMcp = new RaribleProtocolMcp({
  apiKeyAuth: process.env["RARIBLEPROTOCOLMCP_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await raribleProtocolMcp.nftItems.getItemById({
    itemId:
      "ETHEREUM:0xb66a603f4cfe17e3d27b87a8bfcad319856518b8:32292934596187112148346015918544186536963932779440027682601542850818403729410",
  }, {
    retries: {
      strategy: "backoff",
      backoff: {
        initialInterval: 1,
        maxInterval: 50,
        exponent: 1.1,
        maxElapsedTime: 100,
      },
      retryConnectionErrors: false,
    },
  });

  // Handle the result
  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 { RaribleProtocolMcp } from "sei-mcp";

const raribleProtocolMcp = new RaribleProtocolMcp({
  retryConfig: {
    strategy: "backoff",
    backoff: {
      initialInterval: 1,
      maxInterval: 50,
      exponent: 1.1,
      maxElapsedTime: 100,
    },
    retryConnectionErrors: false,
  },
  apiKeyAuth: process.env["RARIBLEPROTOCOLMCP_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await raribleProtocolMcp.nftItems.getItemById({
    itemId:
      "ETHEREUM:0xb66a603f4cfe17e3d27b87a8bfcad319856518b8:32292934596187112148346015918544186536963932779440027682601542850818403729410",
  });

  // Handle the result
  console.log(result);
}

run();

Error Handling

Some methods specify known errors which can be thrown. All the known errors are enumerated in the models/errors/errors.ts module. The known errors for a method are documented under the Errors tables in SDK docs. For example, the getItemById method may throw the following errors:

| Error Type | Status Code | Content Type | | ---------------------------------- | ----------- | ---------------- | | errors.UnionApiErrorBadRequest | 400 | application/json | | errors.UnionApiErrorEntityNotFound | 404 | application/json | | errors.UnionApiErrorServerError | 500 | application/json | | errors.APIError | 4XX, 5XX | */* |

If the method throws an error and it is not captured by the known errors, it will default to throwing a APIError.

import { RaribleProtocolMcp } from "sei-mcp";
import {
  SDKValidationError,
  UnionApiErrorBadRequest,
  UnionApiErrorEntityNotFound,
  UnionApiErrorServerError,
} from "sei-mcp/models/errors";

const raribleProtocolMcp = new RaribleProtocolMcp({
  apiKeyAuth: process.env["RARIBLEPROTOCOLMCP_API_KEY_AUTH"] ?? "",
});

async function run() {
  let result;
  try {
    result = await raribleProtocolMcp.nftItems.getItemById({
      itemId:
        "ETHEREUM:0xb66a603f4cfe17e3d27b87a8bfcad319856518b8:32292934596187112148346015918544186536963932779440027682601542850818403729410",
    });

    // Handle the result
    console.log(result);
  } catch (err) {
    switch (true) {
      // The server response does not match the expected SDK schema
      case (err instanceof SDKValidationError): {
        // Pretty-print will provide a human-readable multi-line error message
        console.error(err.pretty());
        // Raw value may also be inspected
        console.error(err.rawValue);
        return;
      }
      case (err instanceof UnionApiErrorBadRequest): {
        // Handle err.data$: UnionApiErrorBadRequestData
        console.error(err);
        return;
      }
      case (err instanceof UnionApiErrorEntityNotFound): {
        // Handle err.data$: UnionApiErrorEntityNotFoundData
        console.error(err);
        return;
      }
      case (err instanceof UnionApiErrorServerError): {
        // Handle err.data$: UnionApiErrorServerErrorData
        console.error(err);
        return;
      }
      default: {
        // Other errors such as network errors, see HTTPClientErrors for more details
        throw err;
      }
    }
  }
}

run();

Validation errors can also occur when either method arguments or data returned from the server do not match the expected format. The SDKValidationError that is thrown as a result will capture the raw value that failed validation in an attribute called rawValue. Additionally, a pretty() method is available on this error that can be used to log a nicely formatted multi-line string since validation errors can list many issues and the plain error string may be difficult read when debugging.

In some rare cases, the SDK can fail to get a response from the server or even make the request due to unexpected circumstances such as network conditions. These types of errors are captured in the models/errors/httpclienterrors.ts module:

| HTTP Client Error | Description | | ---------------------------------------------------- | ---------------------------------------------------- | | RequestAbortedError | HTTP request was aborted by the client | | RequestTimeoutError | HTTP request timed out due to an AbortSignal signal | | ConnectionError | HTTP client was unable to make a request to a server | | InvalidRequestError | Any input used to create a request is invalid | | UnexpectedClientError | Unrecognised or unexpected error |

Server Selection

Server Variables

The default server https://{environment}.rarible.org contains variables and is set to https://api.rarible.org by default. To override default values, the following parameters are available when initializing the SDK client instance:

| Variable | Parameter | Supported Values | Default | Description | | ------------- | --------------------------------------- | ------------------------------- | ------- | ----------- | | environment | environment: models.ServerEnvironment | - "api"- "testnet-api" | "api" | |

Example

import { RaribleProtocolMcp } from "sei-mcp";

const raribleProtocolMcp = new RaribleProtocolMcp({
  environment: "testnet-api",
  apiKeyAuth: process.env["RARIBLEPROTOCOLMCP_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await raribleProtocolMcp.nftItems.getItemById({
    itemId:
      "ETHEREUM:0xb66a603f4cfe17e3d27b87a8bfcad319856518b8:32292934596187112148346015918544186536963932779440027682601542850818403729410",
  });

  // Handle the result
  console.log(result);
}

run();

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 { RaribleProtocolMcp } from "sei-mcp";

const raribleProtocolMcp = new RaribleProtocolMcp({
  serverURL: "https://api.rarible.org",
  apiKeyAuth: process.env["RARIBLEPROTOCOLMCP_API_KEY_AUTH"] ?? "",
});

async function run() {
  const result = await raribleProtocolMcp.nftItems.getItemById({
    itemId:
      "ETHEREUM:0xb66a603f4cfe17e3d27b87a8bfcad319856518b8:32292934596187112148346015918544186536963932779440027682601542850818403729410",
  });

  // Handle the result
  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 { RaribleProtocolMcp } from "sei-mcp";
import { HTTPClient } from "sei-mcp/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 RaribleProtocolMcp({ 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 { RaribleProtocolMcp } from "sei-mcp";

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

You can also enable a default debug logger by setting an environment variable RARIBLEPROTOCOLMCP_DEBUG to true.

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.
