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 requestsUsage
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 templatesExamples
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
