Understanding the Model Context Protocol (MCP)

References: Model Context Protocol Specification, TypeScript SDK, Official Documentation

The Model Context Protocol (MCP) is an open standard that revolutionizes how AI assistants connect to external data sources and tools. Created by Anthropic and now maintained as an open-source ecosystem, MCP solves the fundamental challenge of providing LLMs with live, contextual information while maintaining security and standardization.

The Problem MCP Solves

Before MCP: The AI integration landscape was fragmented and inefficient:

Core MCP Components

The Model Context Protocol defines four primary components that work together to provide seamless LLM-to-data integration. Think of MCP like a USB-C port for AI applications - providing a standardized interface for connecting AI models to different data sources and tools.

Resources (Data Providers)

"Think of these sort of like GET endpoints; they are used to load information into the LLM's context"

Resources expose data to LLMs without performing significant computation or side effects. They provide a standardized way to access information from various sources.

Key Characteristics:

  • Read-only access: Similar to REST GET endpoints
  • Static or dynamic: Can serve fixed content or generate content based on parameters
  • URI-based addressing: Each resource has a unique URI for identification
  • Content types: Support text, JSON, binary data with MIME type specification

Implementation Examples:

// Static resource - fixed content
server.registerResource(
  "config",
  "config://app",
  {
    title: "Application Config",
    description: "Application configuration data",
    mimeType: "text/plain"
  },
  async (uri) => ({
    contents: [{
      uri: uri.href,
      text: "App configuration here"
    }]
  })
);

// Dynamic resource with parameters
server.registerResource(
  "user-profile",
  new ResourceTemplate("users://{userId}/profile", { list: undefined }),
  {
    title: "User Profile",
    description: "User profile information"
  },
  async (uri, { userId }) => ({
    contents: [{
      uri: uri.href,
      text: `Profile data for user ${userId}`
    }]
  })
);

Tools (Action Providers)

"Sort of like POST endpoints; they are used to execute code or otherwise produce a side effect"

Tools enable LLMs to perform actions and computations through your server. Unlike resources, tools are expected to have side effects and perform meaningful work.

Key Characteristics:

  • Action-oriented: Perform computations, API calls, file operations
  • Input validation: Strongly-typed parameters with Zod schemas
  • Asynchronous execution: Support for long-running operations
  • Rich responses: Can return text, structured data, or resource links

Implementation Examples:

// Simple calculation tool
server.registerTool(
  "calculate-bmi",
  {
    title: "BMI Calculator",
    description: "Calculate Body Mass Index",
    inputSchema: {
      weightKg: z.number(),
      heightM: z.number()
    }
  },
  async ({ weightKg, heightM }) => ({
    content: [{
      type: "text",
      text: String(weightKg / (heightM * heightM))
    }]
  })
);

// Tool with external API integration
server.registerTool(
  "fetch-weather",
  {
    title: "Weather Fetcher",
    description: "Get weather data for a city",
    inputSchema: { city: z.string() }
  },
  async ({ city }) => {
    const response = await fetch(`https://api.weather.com/${city}`);
    const data = await response.text();
    return {
      content: [{ type: "text", text: data }]
    };
  }
);

// Tool returning ResourceLinks (references without content)
server.registerTool(
  "list-files",
  {
    title: "List Files",
    description: "List project files",
    inputSchema: { pattern: z.string() }
  },
  async ({ pattern }) => ({
    content: [
      { type: "text", text: `Found files matching "${pattern}":` },
      {
        type: "resource_link",
        uri: "file:///project/README.md",
        name: "README.md",
        mimeType: "text/markdown",
        description: 'A README file'
      }
    ]
  })
);

Prompts (Template Providers)

"Reusable templates for LLM interactions"

Prompts are pre-defined templates that help structure interactions between LLMs and your server. They provide consistent, reusable patterns for common tasks.

Key Characteristics:

  • Template-based: Parameterized templates for consistent interactions
  • Context-aware completion: Intelligent parameter suggestions based on context
  • Structured messages: Define role-based conversation flows
  • Reusability: Share common interaction patterns across different contexts

Implementation Examples:

// Simple code review prompt
server.registerPrompt(
  "review-code",
  {
    title: "Code Review",
    description: "Review code for best practices and potential issues",
    argsSchema: { code: z.string() }
  },
  ({ code }) => ({
    messages: [{
      role: "user",
      content: {
        type: "text",
        text: `Please review this code:\n\n${code}`
      }
    }]
  })
);

// Context-aware prompt with intelligent completion
server.registerPrompt(
  "team-greeting",
  {
    title: "Team Greeting",
    description: "Generate a greeting for team members",
    argsSchema: {
      department: completable(z.string(), (value) => {
        return ["engineering", "sales", "marketing", "support"]
          .filter(d => d.startsWith(value));
      }),
      name: completable(z.string(), (value, context) => {
        const dept = context?.arguments?.["department"];
        if (dept === "engineering") {
          return ["Alice", "Bob", "Charlie"].filter(n => n.startsWith(value));
        }
        return ["Default"].filter(n => n.startsWith(value));
      })
    }
  },
  ({ department, name }) => ({
    messages: [{
      role: "user",
      content: {
        type: "text",
        text: `Generate a greeting for ${name} from the ${department} department`
      }
    }]
  })
);

Sampling (LLM Communication)

"Enable server-to-LLM requests for AI-powered features"

Sampling allows MCP servers to request completions from LLMs, enabling servers to leverage AI capabilities within their tools and workflows.

Key Characteristics:

  • Server-initiated: Servers can request LLM completions during tool execution
  • Bidirectional communication: Enables complex workflows with AI reasoning
  • Token control: Configurable limits and parameters for completion requests
  • Integration-ready: Seamlessly integrates with existing tool implementations

Implementation Examples:

// Tool that uses LLM sampling for text summarization
server.registerTool(
  "summarize",
  {
    description: "Summarize any text using an LLM",
    inputSchema: {
      text: z.string().describe("Text to summarize"),
    },
  },
  async ({ text }) => {
    // Call the LLM through MCP sampling
    const response = await server.server.createMessage({
      messages: [
        {
          role: "user",
          content: {
            type: "text",
            text: `Please summarize the following text concisely:\n\n${text}`,
          },
        },
      ],
      maxTokens: 500,
    });

    return {
      content: [
        {
          type: "text",
          text: response.content.type === "text" 
            ? response.content.text 
            : "Unable to generate summary",
        },
      ],
    };
  }
);

Additional Important Insights

Context7 Transport Support

Context7 supports multiple transport methods including HTTP, SSE, and stdio, making it flexible for different deployment scenarios. The remote service uses HTTP transport for global accessibility with configurable port settings (default: 3000).

GitHub Official MCP Toolset Structure

The GitHub MCP server uses a sophisticated toolset architecture where tools are organized into 14 logical groups that can be selectively enabled/disabled. This allows fine-grained control over which GitHub capabilities are exposed to AI assistants. Recent additions include discussion tools and enhanced Dependabot alert management.

AWS MCP Suite Transport Changes

Important Notice: As of May 26, 2025, Server-Sent Events (SSE) support was removed from all AWS MCP servers. They have transitioned to Streamable HTTP transport, which provides improved capabilities and aligns with MCP specification standards.
