SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Tool Lab Plugin enables teams to design, audit, and dispatch MCP tools using a standardized action/subaction pattern, reducing boilerplate and ensuring consistency across plugins.

Core Features & Use Cases

  • Canonical error shape enforcement for tool failures.
  • Action/subaction dispatch tables across Python, Rust, and TypeScript patterns.
  • Help tool and documentation scaffolding to expose capabilities at runtime.
  • Guidance for creating new tools, reviewing existing ones, and updating tool definitions.
  • Cross-language templates and references to maintain uniform implementations.

Quick Start

Create a new MCP tool by defining its action/subaction contract and dispatch handlers.

FAQPage Schema
How do I create MCP tools using an action/subaction dispatch pattern?

To create MCP tools using an action/subaction dispatch pattern, define the action/subaction contract and dispatch handlers to automate tool creation and validation. The dispatch tables provide standardized routing across Python, Rust, and TypeScript implementations.

What is a canonical error shape for MCP tool failures?

A canonical error shape for MCP tool failures is a standardized error response format enforced during tool design and auditing. It ensures consistent error handling across all MCP tools, reducing boilerplate and maintaining uniform implementations.

Can I generate scaffolding artifacts for MCP tools in Python, Rust, and TypeScript?

Yes, you can generate cross-language scaffolding artifacts for MCP tools in Python, Rust, and TypeScript. The templates provide uniform implementation references, including help tool and documentation scaffolding to expose capabilities at runtime.

How do I audit existing MCP tools for conformance?

To audit existing MCP tools for conformance, review them against the standardized action/subaction dispatch pattern and canonical error shape. This process ensures existing implementations adhere to centralized references and cross-language consistency guidelines.

What is the best way to standardize MCP tool design across multiple programming languages?

The best way to standardize MCP tool design across multiple programming languages is to use cross-language templates and centralized references. Applying an action/subaction dispatch pattern enforces uniform implementations and reduces boilerplate across Python, Rust, and TypeScript.
