对比MCP官方python SDK和Typescript SDK

官方支持的所有语言 https://modelcontextprotocol.io/docs/sdk
官方 python SDK https://github.com/modelcontextprotocol/python-sdk
官方 Typescript SDK https://github.com/modelcontextprotocol/typescript-sdk

官方SDK支持的前两位分别是python和Typescript. 这儿对比一下两者编程的复杂度.

导入库:

py

from mcp.server.fastmcp import FastMCP

ts

import { McpServer, ResourceTemplate } from '@modelcontextprotocol/sdk/server/mcp.js';
import { StreamableHTTPServerTransport } from '@modelcontextprotocol/sdk/server/streamableHttp.js';
import express from 'express';
import * as z from 'zod/v4';

新建server

py

# Create an MCP server
mcp = FastMCP("Demo", json_response=True)

ts

// Create an MCP server
const server = new McpServer({
    name: 'demo-server',
    version: '1.0.0'
});

加入工具

py

# Add an addition tool
@mcp.tool()
def add(a: int, b: int) -> int:
    """Add two numbers"""
    return a + b

ts

// Add an addition tool
server.registerTool(
    'add',
    {
        title: 'Addition Tool',
        description: 'Add two numbers',
        inputSchema: { a: z.number(), b: z.number() },
        outputSchema: { result: z.number() }
    },
    async ({ a, b }) => {
        const output = { result: a + b };
        return {
            content: [{ type: 'text', text: JSON.stringify(output) }],
            structuredContent: output
        };
    }
);

加入资源

py

# Add a dynamic greeting resource
@mcp.resource("greeting://{name}")
def get_greeting(name: str) -> str:
    """Get a personalized greeting"""
    return f"Hello, {name}!"

ts

// Add a dynamic greeting resource
server.registerResource(
    'greeting',
    new ResourceTemplate('greeting://{name}', { list: undefined }),
    {
        title: 'Greeting Resource', // Display name for UI
        description: 'Dynamic greeting generator'
    },
    async (uri, { name }) => ({
        contents: [
            {
                uri: uri.href,
                text: `Hello, ${name}!`
            }
        ]
    })
);

启动服务

py

# Run with streamable HTTP transport
if __name__ == "__main__":
    mcp.run(transport="streamable-http")

ts

// Set up Express and HTTP transport
const app = express();
app.use(express.json());

app.post('/mcp', async (req, res) => {
    // Create a new transport for each request to prevent request ID collisions
    const transport = new StreamableHTTPServerTransport({
        sessionIdGenerator: undefined,
        enableJsonResponse: true
    });

    res.on('close', () => {
        transport.close();
    });

    await server.connect(transport);
    await transport.handleRequest(req, res, req.body);
});

const port = parseInt(process.env.PORT || '3000');
app.listen(port, () => {
    console.log(`Demo MCP Server running on http://localhost:${port}/mcp`);
}).on('error', error => {
    console.error('Server error:', error);
    process.exit(1);
});

结论

很显然python代码更短, python库封装的更多.
