Exploring the Model Context Protocol (MCP) through practical guides, clients, and servers I've built while learning about this new protocol.

Overview

What is Model Context Protocol Resources

The Model Context Protocol (MCP) is a standardized communication protocol that allows Large Language Models (LLMs) to interact with external systems and services, providing a consistent interface for accessing tools and resources.

Use cases

Use cases for MCP include building intelligent assistants that can query databases, integrating LLMs with web APIs for real-time data retrieval, and developing applications that require structured access to external resources.

How to use

Users can implement the MCP by utilizing the available SDKs in TypeScript, Python, and Kotlin. The guides and utilities provided in the repository can help in setting up clients and servers to facilitate communication between LLMs and external systems.

Key features

Key features of MCP include a consistent interface for LLMs, enhanced capabilities for interaction with databases and APIs, built-in security and control mechanisms, and extensibility for future developments.

Where to use

MCP can be used in various fields such as AI development, data analysis, and application integration where LLMs need to communicate with other systems or services.

This repository is a collection of guides, utilities, and server implementations for the Model Context Protocol (MCP) created while learning MCP. It reflects my ongoing exploration and development with this exciting new standard for creating powerful Agent capabilities. Questions and feedback are welcome! 🚀

Disclaimer: The resources in this repository (guides, utilities, server implementations, and the MCP TypeScript Template) were developed independently by cyanheads while exploring the Model Context Protocol. This project is not officially affiliated with the Model Context Protocol organization. Links to official MCP resources are provided below. I appreciate the work of the official MCP team on the specification, SDKs, and documentation!

🔍 Introduction to MCP

The Model Context Protocol (MCP) is an open standard designed to standardize how AI applications (clients/hosts) connect to and interact with external data sources and tools (servers).
Think of it like USB-C for AI: a universal way to plug capabilities into LLM applications.

Key Benefits:

  • Consistent Interface: Standardized methods for LLMs to access tools and resources.
  • Enhanced Capabilities: Empowers LLMs to interact with databases, APIs, local systems, and more.
  • Security & Control: Provides structured access patterns with built-in validation and clear boundaries.
  • Extensibility: Easily add new capabilities via servers without modifying core LLM applications.
  • Modularity: Develop and maintain specialized functionalities in isolated, reusable server components.

🚀 MCP TypeScript Template Repo

Project Description
mcp-ts-template Provides a beginner-friendly, production-ready template for building MCP servers and clients. Includes essential utilities, examples, and type safety for a solid starting point.

📚 MCP Guides

Guide Description
MCP Client Development Guide Learn how to build applications that consume MCP server capabilities. Covers core architecture, lifecycle, tools/resources, security, examples, and advanced topics. (Note: Needs update for latest spec changes)
MCP Server Development Guide Comprehensive guide to building MCP servers. Covers core architecture, protocol fundamentals, server lifecycle, transports (Stdio, Streamable HTTP), building with the TypeScript SDK, defining Tools/Resources/Prompts, advanced features (sampling, roots, streaming, progress, subscriptions, completions), security best practices (updated for Auth Spec 2025-03-26), troubleshooting, and example implementations. (Updated May 2025)
Cyanhead’s MCP ‘llms.txt’ A custom llms.txt for faster TypeScript MCP server development using the high-level SDK (McpServer). Tailored for LLM consumption, it covers key concepts, high-level examples, security, and dynamic capabilities, updated for Spec 2025-03-26 & TS SDK v1.11.0.

🔧 MCP Utilities

Project Description
mcp-reporter Generates comprehensive capability reports for MCP servers, helping developers understand available functionality across their MCP ecosystem for documentation and integration.

🔌 MCP Servers

This repository hosts several example MCP server implementations, showcasing different capabilities:

Project Description
atlas-mcp-server ATLAS (Adaptive Task & Logic Automation System), a Neo4j-powered task management system designed for LLM Agents. It uses a three-tier architecture (Projects, Tasks, Knowledge) to manage complex workflows and includes Deep Research scaffolding.
clinicaltrialsgov-mcp-server Enables AI agents to search, retrieve, and analyze clinical study data from ClinicalTrials.gov programmatically via MCP.
filesystem-mcp-server Offers platform-agnostic file system capabilities for AI agents via MCP, enabling file and directory management. Features advanced search/replace and directory traversal.
git-mcp-server Provides an enterprise-ready MCP interface for Git operations, allowing LLMs to initialize, clone, branch, commit, and manage repositories via STDIO & Streamable HTTP.
github-mcp-server Integrates with the GitHub API via MCP, providing a structured interface for LLM agents to manage repositories, issues, pull requests, code, files, and releases.
mentor-mcp-server Offers AI-powered mentorship via MCP using the Deepseek API, providing LLM agents with a ‘second opinion’. Can be used for code review, design critique, writing feedback, and brainstorming.
ntfy-mcp-server Integrates with the ntfy.sh push notification service via MCP, enabling LLMs to send highly customizable notifications to external devices.
obsidian-mcp-server Enables LLMs to securely interact with Obsidian vaults via MCP, offering token-aware tools for managing notes. Facilitates seamless knowledge base management with Properties management.
perplexity-mcp-server Unlocks Perplexity’s search-augmented AI capabilities for your LLMs via MCP. Provides access to real-time web information with robust error handling and secure validation.
pubmed-mcp-server Connects AI agents to NCBI’s PubMed and E-utilities via MCP, enabling search, retrieval, and analysis of biomedical literature.
toolkit-mcp-server Provides essential system utilities and tools for LLM agents via MCP. Features include IP geolocation, network diagnostics, system monitoring, cryptographic operations, and QR code generation.
workflows-mcp-server Empowers AI agents with a powerful, declarative workflow engine to discover, understand, and execute complex, multi-step workflows defined in simple YAML files. Easy as asking your LLM “Create a new workflow to do xyz using the tools you currently have access to”
