Mcp Client

# 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

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

Usage

Connect to MCP Server

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

List Available Tools

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

Call a Tool

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

List Resources

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

Read a Resource

```powershell .\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

```python 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
