SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides in-depth knowledge of the Model Context Protocol (MCP) to ensure spec compliance, debug client compatibility issues, and implement protocol behaviors correctly.

Core Features & Use Cases

  • Protocol Understanding: Deep dive into MCP specifics including wire formats (JSON-RPC 2.0), transports (STDIO, SSE, HTTP), version negotiation, tool schemas, resource URIs, and prompt handling.
  • Client Compatibility: Debug and resolve issues related to how AI clients interact with the MCP server.
  • Spec Implementation: Ensure new features or modifications adhere strictly to the MCP specification.
  • Use Case: When developing a new AI tool that needs to integrate with the MCP server, use this Skill to understand the required initialize parameters for version negotiation and the expected structure of tool input/output schemas.

Quick Start

Use the mcp-expertise skill to understand how to handle version negotiation in the MCP protocol.

Frequently Asked Questions about mcp-expertise

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How does Model Context Protocol handle version negotiation between clients and servers?▼

Model Context Protocol version negotiation requires specific initialize parameters exchanged between clients and servers. This Skill explains the expected initialize structure, ensuring proper version agreement and preventing compatibility issues during client-server connections.

How do I implement JSON-RPC 2.0 wire format for MCP servers?▼

Implementing JSON-RPC 2.0 wire format for MCP servers involves structuring requests and responses according to protocol specifications. This Skill provides deep expertise on wire formats, including batching and cancellation, ensuring correct message handling.

What transports does MCP support for AI tool integration?▼

MCP supports STDIO, SSE, and HTTP transports for AI tool integration. This Skill details how to configure these transports, including CORS configurations, ensuring reliable communication channels between MCP-compliant servers and AI clients.

Why is my MCP client compatibility failing during tool and resource handling?▼

MCP client compatibility failures during tool and resource handling often stem from incorrect tool input/output schemas or resource URI structures. This Skill helps debug these issues by providing correct protocol specifications for tool schemas and resource URIs.

Can I use MCP protocol for prompt mechanisms in AI tools?▼

Yes, the MCP protocol includes specific prompt mechanisms for AI tools. This Skill covers prompt handling alongside tool and resource management, ensuring developers implement prompt behaviors strictly according to the MCP specification.

What are the limitations when configuring CORS for SSE transports in MCP?▼

Configuring CORS for SSE transports in MCP requires strict adherence to protocol specifications to avoid connection failures. This Skill outlines the necessary CORS configurations and constraints, helping developers anticipate edge cases and ensure stable SSE transport communication.
