This repository contains the TypeScript SDK implementation of the MCP specification and ships: MCP server libraries (tools/resources/prompts, Streamable HTTP, stdio, auth helpers) MCP client libraries (transports, high-level helpers, OAuth helpers) ... Both packages have a required peer dependency on zod for schema validation. The SDK internally imports from zod/v4, but remains compatible with projects using Zod v3.25+. ... The runnable examples live under examples/ and are kept in sync with the docs.

It demonstrates how to use Node.js and TypeScript to build a remote MCP server and deploy it to Azure Container Apps.

April 3, 2025 - Let’s create a new MCP server that can gather data from the CocktailDB API and gives us drinks recipes. Create a new folder and setup a new TypeScript project following the previous steps.

In this tutorial, we'll focus on building an MCP server using the TypeScript SDK. We’ll use Claude Desktop as our host for testing. Begin by creating a new project and initializing an npm package. Add the necessary dependencies for the MCP server and TypeScript. Ensure your project includes configuration files like package.json and tsconfig.json: ... { "name": "mcp-server", "version": "0.1.0", "description": "A Model Context Protocol server example", "private": true, "type": "module", "bin": { "mcp-server": "./build/index.js" }, "files": [ "build" ], "scripts": { "build": "tsc && node -e \"r

June 27, 2025 - So, to build an MCP server, we've landed on the official GitHub repo page for MCP's TypeScript SDK. Now, for those of you who don't know TypeScript, there's nothing to worry about. Because TypeScript is basically a superset of JavaScript. So even if you're not familiar with TypeScript, it's ...

March 20, 2025 - Also we do need to be able to call Pulumi API, I already created a very basic Client for it in Typescript will share that at the end of the article in a repository. First thing is that we need to install the protocol SDK. ... import { McpServer, ResourceTemplate } from "@modelcontextprotocol/sdk/server/mcp.js"; import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js"; import { z } from "zod"; const pulumiClient = new PulumiClient('token'); // Create an MCP server const server = new McpServer({ name: "Pulumi MCP Server", version: "1.0.0" }); // ...

// Main execution async function main() { if (process.argv.length < 3) { console.log("Usage: ts-node client.ts <path_to_server_script>"); process.exit(1); } const client = new MCPClient(); try { await client.connectToServer(process.argv[2]); await client.chatLoop(); } catch (error) { console.error("Error:", error); await client.cleanup(); process.exit(1); } } // Run main if this is the main module if (import.meta.url === new URL(process.argv[1], "file:").href) { main(); } export default MCPClient; ... # Build the TypeScript code.

Fully working samples (Hosted tools/Streamable HTTP/stdio + Streaming, HITL, onApproval) are examples/mcp in our GitHub repository. Section titled “2. Streamable HTTP MCP servers” · When your Agent talks directly to a Streamable HTTP MCP server—local or remote—instantiate MCPServerStreamableHttp with the server url, name, and any optional settings: ... The constructor also accepts additional MCP TypeScript‑SDK options such as authProvider, requestInit, fetch, reconnectionOptions, and sessionId.

Latest version: 1.10.1-dev, last published: 7 months ago. Start using @moinfra/mcp-client-sdk in your project by running `npm i @moinfra/mcp-client-sdk`. There are no other projects ...

February 18, 2025 - For each method in the SDK, the MCP server will have a generated tool. The tool represents a discrete action that the AI agent can take. For example, the bluesky-ts SDK has a getFeed method that enables agents to fetch a user’s feed from Bluesky.

A more complex example showing database integration: import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js"; import sqlite3 from "sqlite3"; import { promisify } from "util"; import { z } from "zod"; const server = new McpServer({ name: "SQLite Explorer", version: "1.0.0" }); // Helper to create DB connection const getDb = () => { const db = new sqlite3.Database("database.db"); return { all: promisify<string, any[]>(db.all.bind(db)), close: promisify(db.close.bind(db)) }; }; server.resource( "schema", "schema://main", async (uri) => { const db = getDb(); try { const tables = await

Your client will need a key in order to invoke the new hosted SSE endpoint, which will be of the form https://<funcappname>.azurewebsites.net/runtime/webhooks/mcp/sse. The hosted function requires a system key by default which can be obtained ...

March 19, 2025 - The TypeScript SDK (@modelcontextprotocol/sdk) brings this protocol to life, offering a simple yet powerful way to create MCP servers and clients. Whether you’re building a command-line tool or a web service, MCP has you covered with standard transports like stdio and Server-Sent Events (SSE). Let’s jump into a quick example ...

November 29, 2024 - Some context: Speakeasy lets you generate SDKs from OpenAPI 3.x specs and now every user that generates a TypeScript SDK gets a Model Context Protocol (MCP) server bundled with it. This is available to users on both free and paid tiers · I've been the primary maintainer of TypeScript SDK codegen ...

This template implements a basic MCP server that provides tools for: Example operation: A simple demonstration operation ... The server uses the Model Context Protocol SDK to handle communication between AI models and external tools.

1 month ago - This guide will walk you through creating an MCP server in TypeScript, tailored for those who already have services and want to expose them as MCP tools. We’ll use a simple math-tool as an example, showing how you can adapt your own services into an MCP setup.

# Create a new directory for your project mkdir mcp-sqlite-server cd mcp-sqlite-server # Initialize your project npm init -y # Install required dependencies npm install @mcp/sdk@latest sqlite3 better-sqlite3 typescript ts-node @types/node # Initialize TypeScript configuration npx tsc --init

This pair of examples demonstrates tools, resources, prompts, sampling, elicitation, tasks and logging. For a guided walkthrough and variations (stateless servers, JSON-only responses, SSE compatibility, OAuth, etc.), see docs/server.md and docs/client.md. An MCP server is typically created with McpServer and connected to a transport such as Streamable HTTP or stdio. The SDK supports:
