How to Set Up and Use Gopher

Gopher MCP (gopher-mcp) is a C++ SDK and reference implementation for the Model Context Protocol, providing enterprise-grade MCP server capabilities with support for multiple transport protocols including stdio, HTTP+SSE, HTTPS+SSE, WebSocket, and TCP. It is designed for teams building high-performance or embedded MCP servers in C++ environments, offering cross-language bindings via a C API so that Python, TypeScript, Go, Rust, Java, C#, and Ruby clients can all interface with it.

Prerequisites

  • A C++14-compatible compiler (GCC, Clang, or MSVC)
  • CMake 3.10 or higher for building
  • libevent 2.1+ for async event handling
  • OpenSSL 1.1+ if using HTTPS or WSS transports (optional for plain HTTP/stdio)
  • An MCP-compatible client for testing the built server
1

Clone the repository

Clone the gopher-mcp repository from GitHub.

git clone https://github.com/GopherSecurity/gopher-mcp.git
cd gopher-mcp
2

Build the project

Use the provided Makefile to compile the SDK and example servers. The default target produces a release build.

make
3

Run the tests

Verify the build is working correctly by running the test suite.

make test
4

Install the SDK

Install the compiled library and headers system-wide (may prompt for sudo).

make install
5

Register a custom tool in your server

In your C++ application, include the MCP SDK headers, create a Tool object with a name and description, register a callback handler, and start listening. The server will be reachable on the configured port or via stdio.

// Example: register a tool and start the server
#include <mcp/server.h>
mcp::Tool myTool;
myTool.name = "my_tool";
myTool.description = "Does something useful";
server->registerTool(myTool, [](const std::string& name,
    const mcp::optional<mcp::Metadata>& args,
    mcp::server::SessionContext& ctx) {
  // handler logic
});
server->listen("http://0.0.0.0:3000");
6

Configure your MCP client

For stdio mode, point your MCP client at the compiled binary. For HTTP mode, use the server's URL.

{
  "mcpServers": {
    "gopher": {
      "command": "/path/to/gopher-mcp-server",
      "args": []
    }
  }
}

Gopher Examples

Client configuration

MCP client configuration for a gopher-mcp server compiled and running locally in stdio mode.

{
  "mcpServers": {
    "gopher": {
      "command": "/usr/local/bin/gopher-mcp-server",
      "args": []
    }
  }
}

Prompts to try

Example prompts for a C++ MCP server built with the Gopher SDK, assuming standard example tools are registered.

- "Add 42 and 58 using the calculator tool"
- "Query the database for all users created this month"
- "Get system information including CPU and memory usage"
- "List all registered tools on this MCP server"

Troubleshooting Gopher

Build fails with 'libevent not found'

Install libevent development headers. On Ubuntu/Debian: 'sudo apt-get install libevent-dev'. On macOS with Homebrew: 'brew install libevent'. Then re-run 'make'.

Linker errors about undefined OpenSSL symbols

Install OpenSSL development libraries: 'sudo apt-get install libssl-dev' on Ubuntu or 'brew install openssl' on macOS. If you don't need HTTPS, check if there is a build flag to disable TLS support in the CMakeLists.txt.

MCP client cannot connect to the server on port 3000

Verify the server is running ('make run' or launch your compiled binary) and that no firewall is blocking port 3000. For local development, use stdio transport instead of HTTP to avoid networking issues.
