SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill simplifies the process of integrating new tools into the Model Context Protocol (MCP) server, ensuring consistency and reducing manual setup.

Core Features & Use Cases

  • Streamlined Tool Integration: Guides users through defining, implementing, and testing new MCP tools.
  • Ensures Consistency: Follows a structured workflow for tool definition and handler implementation.
  • Use Case: A developer needs to add a new tool to query memory addresses from the Regenerator 2000 disassembler. This Skill will walk them through defining the tool's parameters, writing the Rust handler, and adding a verification test.

Quick Start

Use the add-mcp-tool skill to add a new tool named 'r2000_get_register' that takes a register name as input and returns its value.

FAQPage Schema
How do I add a new tool to an MCP server?

To add a new tool to an MCP server, you must define its JSON schema specifications, implement the handler logic in Rust, and write verification tests in Python. This ensures proper argument handling and protocol compliance.

How does tool integration work with the Model Context Protocol?

Tool integration with the Model Context Protocol works by adhering to a structured workflow that defines tool specifications using a JSON schema. This guarantees that argument handling and handler implementation follow MCP standards.

What is the best way to implement MCP tool handlers in Rust?

The best way to implement MCP tool handlers in Rust is by following a structured workflow that ensures consistency across tool definitions. This approach standardizes argument handling and integrates seamlessly with the MCP server.

Do I need Python to verify new MCP server tools?

Yes, you need Python to add verification tests for new MCP server tools. Writing tests in Python is a required step in the tool integration workflow to validate the Rust handler logic and ensure correct functionality.

Can I use this workflow to add a tool that queries a disassembler?

Yes, you can use this workflow to add a tool that queries a disassembler. The process guides you through defining parameters, writing the Rust handler, and adding verification tests for specific use cases like querying memory addresses.

Why does MCP tool integration require a JSON schema for definitions?

MCP tool integration requires a JSON schema for definitions to ensure proper argument handling and protocol compliance. Adhering to this schema guarantees that the new tool integrates consistently into the MCP server architecture.
