MCP Protocol Framework

Core Features

JSON-RPC 2.0 Communication: Request/response communication based on JSON-RPC 2.0 standard
Resource Abstraction: Standard interfaces for resources such as files, APIs, etc.
Tool Registration: Register and call tools with structured parameters
Extensible Architecture: Easy to extend with new resource types and tools
Multi-Transport Support: Supports HTTP and standard input/output (stdio) communication methods

How to Build

Example of building with CMake:

cmake -B build
cmake --build build --config Release

Build with tests:

git submodule update --init --recursive # Get GoogleTest

cmake -B build -DMCP_BUILD_TESTS=ON
cmake --build build --config Release

Build with SSL support:

git submodule update --init --recursive # Get GoogleTest

cmake -B build -DMCP_SSL=ON
cmake --build build --config Release

Components

The MCP C++ library includes the following main components:

Core Components

Client Interface (`mcp_client.h`)

Defines the abstract interface for MCP clients, which all concrete client implementations inherit from.

SSE Client (`mcp_sse_client.h`, `mcp_sse_client.cpp`)

Client implementation that communicates with MCP servers using HTTP and Server-Sent Events (SSE).

Stdio Client (`mcp_stdio_client.h`, `mcp_stdio_client.cpp`)

Client implementation that communicates with MCP servers using standard input/output, capable of launching subprocesses and communicating with them.

Message Processing (`mcp_message.h`, `mcp_message.cpp`)

Handles serialization and deserialization of JSON-RPC messages.

Tool Management (`mcp_tool.h`, `mcp_tool.cpp`)

Manages and invokes MCP tools.

Resource Management (`mcp_resource.h`, `mcp_resource.cpp`)

Manages MCP resources.

Server (`mcp_server.h`, `mcp_server.cpp`)

Implements MCP server functionality.

Examples

HTTP Server Example (`examples/server_example.cpp`)

Example MCP server implementation with custom tools:

Time tool: Get the current time
Calculator tool: Perform mathematical operations
Echo tool: Echo input with optional transformations (to uppercase, reverse)
Greeting tool: Returns Hello, + input name + !, defaults to Hello, World!

HTTP Client Example (`examples/client_example.cpp`)

Example MCP client connecting to a server:

Get server information
List available tools
Call tools with parameters
Access resources

Stdio Client Example (`examples/stdio_client_example.cpp`)

Demonstrates how to use the stdio client to communicate with a local server:

Launch a local server process
Access filesystem resources
Call server tools

Agent Example (`examples/agent_example.cpp`)

Option	Description
`--base-url`	LLM base URL (e.g. `https://openrouter.ai`)
`--endpoint`	LLM endpoint (default to `/v1/chat/completions/`)
`--api-key`	LLM API key
`--model`	Model name (e.g. `gpt-3.5-turbo`)
`--system-prompt`	System prompt
`--max-tokens`	Maximum number of tokens to generate (default to 2048)
`--temperature`	Temperature (default to 0.0)
`--max-steps`	Maximum steps calling tools without user input (default to 3)

Example usage:

./build/examples/agent_example --base-url <base_url> --endpoint <end
