GameCode MCP2 MCP Server

What is GameCode MCP2?

GameCode MCP2 is a clean implementation of the Model Context Protocol (MCP) for dynamic tool integration. It exposes tools defined in a YAML configuration file directly via MCP, supporting both built-in handlers and external commands, and communicates over stdio using pure JSON-RPC 2.0 without external dependencies.

How to use GameCode MCP2?

Compile the server with cargo build --release --bin gamecode-mcp2, create a tools.yaml file (see examples/tools.yaml), then run the server binary. It communicates via stdio and can be configured as an MCP server in Claude Desktop or integrated via the mcp-client crate.

Key features of GameCode MCP2

• Tools defined in tools.yaml are exposed directly via MCP, not through meta-tools
• Pure JSON-RPC 2.0 over stdio without external dependencies
• Dynamic tool loading – configure tools via YAML without recompiling
• Support for both internal handlers and external commands

Use cases of GameCode MCP2

• Exposing custom command-line tools as MCP tools for AI assistants
• Building a lightweight MCP server with minimal dependencies
• Integrating MCP into a CLI application (gamecode-cli) via the provided client crate
• Rapidly prototyping and testing MCP tool configurations with YAML
