Extend Claude Code's capabilities with MCP servers. Connect to external tools, data sources, and services with the latest 2025 features including remote servers and OAuth.
MCP transforms Claude from a passive assistant into an active tool that can manipulate files, run commands, access real-time data, and perform complex multi-step operations across different platforms.
Connect to remote MCP servers without running them locally. Access cloud-based services and enterprise tools directly.
Secure authentication to remote MCP servers with OAuth. No API keys to manage or credentials to store manually.
Enhanced connectivity with HTTP + Server-Sent Events (SSE) for improved performance and reliability.
Get started with essential MCP servers in minutes. Choose your setup method based on your experience level.
Install essential MCP servers with a single command. Perfect for getting started quickly.

Remote MCP support allows Claude Code to connect to cloud-based MCP servers without running them locally. This enables access to enterprise services, cloud APIs, and shared development tools.
Example configuration for connecting to remote MCP servers with OAuth authentication.
{
"mcpServers": {
"enterprise-github": {
"type": "remote",
"url": "https://mcp.example.com/github",
"oauth": {
"provider": "github",
"scopes": ["repo", "issues", "pull_requests"]
}
},
"company-tools": {
"type": "remote",
"url": "https://internal-mcp.company.com/tools",
"oauth": {
"provider": "company-sso",
"scopes": ["tools:read", "tools:write"]
}
}
}
}OAuth Flow: Claude Code will automatically handle the OAuth authentication flow, opening your browser for secure login when needed.

Secure authentication with OAuth for remote MCP servers without managing API keys manually.
Claude Code now supports native OAuth authentication for remote MCP servers, eliminating the need to manually manage API keys.

"mcpServers": {
"github": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-github"],
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "oauth:github"
}
}
}
}Simple steps to configure OAuth authentication for your MCP servers.
Build and deploy your own MCP servers to extend Claude Code with custom functionality.
Create custom MCP servers using the official SDK and templates.
import { Server } from '@modelcontextprotocol/sdk/server/index.js';
import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js';
const server = new Server(
{
name: 'my-custom-server',
version: '0.1.0',
},
{
capabilities: {
tools: {},
},
}
);
// Add your custom tools here
server.setRequestHandler(ListToolsRequestSchema, async () => {
return {
tools: [
{
name: 'my_tool',
description: 'My custom tool',
inputSchema: {
type: 'object',
properties: {},
},
},
],
};
});
const transport = new StdioServerTransport();
await server.connect(transport);Various ways to deploy and distribute your custom MCP servers.
