Mcp Client

实现 Model Context Protocol 客户端，通过 HTTP 连接 MCP 服务器，列出并调用其暴露的工具、读取资源、获取提示模板；依赖 Python 3.8+ 与 requests，需要服务器地址及可选 API Key。使用说明中引用的 PowerShell 入口脚本未包含在文件列表中。

MCP Client Skill

Implementation of the Model Context Protocol (MCP) client for connecting to tools and data sources.

What it does

  • Connect to MCP Servers - Access tools and resources from MCP-enabled services
  • Tool Invocation - Call tools exposed by MCP servers
  • Resource Access - Read files, databases, APIs
  • Prompt Templates - Use structured prompts from MCP servers

Installation

# Install Python dependencies (requests is the only required dependency)
pip install requests

Usage

Connect to MCP Server

.\mcp.ps1 -Action connect -ServerUrl "https://mcp-server.com" -ApiKey "your-key"

List Available Tools

.\mcp.ps1 -Action tools -ServerUrl "https://mcp-server.com"

Call a Tool

.\mcp.ps1 -Action call -ServerUrl "https://mcp-server.com" -ToolName "search" -Arguments '{"query": "AI agents"}'

List Resources

.\mcp.ps1 -Action resources -ServerUrl "https://mcp-server.com"

Read a Resource

.\mcp.ps1 -Action read -ServerUrl "https://mcp-server.com" -ResourceUri "file:///data/config.json"

MCP Concepts

  • MCP Server: Service that exposes tools, resources, and prompts
  • Tools: Functions the LLM/agent can call
  • Resources: Data sources (files, APIs, DBs)
  • Prompts: Pre-defined prompt templates

API Reference

POST /mcp/connect     - Connect to server
GET  /mcp/tools       - List available tools
POST /mcp/call       - Invoke a tool
GET  /mcp/resources  - List resources
GET  /mcp/read       - Read resource
GET  /mcp/prompts    - List prompt templates

Examples

Python Usage

from mcp_client import MCPClient

client = MCPClient("https://mcp-server.com", api_key="key")

# List tools
tools = client.list_tools()
print(tools)

# Call tool
result = client.call_tool("search", {"query": "quantum"})
print(result)

# Read resource
data = client.read_resource("file:///config.json")
print(data)

⚠️ Security Warnings

file:// URI Risk

The MCP protocol allows file:///path URIs to read files from the server. Only connect to trusted MCP servers. A malicious server could exfiltrate sensitive files.

Best Practices

  • Only use MCP servers you control or trust
  • Don't connect to random public MCP servers
  • Review what tools/resources are available before using

Requirements

  • Review what tools/resources are available before using

  • Python 3.8+

  • requests library
