mcp-spec
Overview
The mcp-spec is a Model Context Protocol (MCP) server that provides AI assistants with direct, structured access to the MCP specification itself. It allows AI-driven workflows to reference the official protocol definition, concepts, and semantics while reasoning about MCP servers, tools, transports, and behaviors.
This server is especially useful for MCP client and server development, protocol education, validation, and tooling workflows where assistants need authoritative, spec-accurate context.

Key Capabilities
- Authoritative protocol reference — Ground AI reasoning in the official MCP specification.
- Reduced hallucination risk — Ensure explanations and guidance align with the actual protocol definition.
- Developer enablement — Support MCP client and server authors with accurate, contextual answers.
- Concept discovery — Explore MCP terminology, abstractions, and design principles programmatically.
- Specification-aware tooling — Enable AI assistants to validate assumptions about MCP behavior.
How It Works
The mcp-spec runs as an MCP service that exposes the MCP specification as structured reference content. AI clients connect over the MCP protocol and request relevant sections or concepts from the spec as part of broader reasoning workflows.
The server retrieves and returns authoritative spec content in a structured format that AI assistants can reason over, summarize, or cite. By centralizing access to the specification, the server ensures consistent interpretation of MCP concepts across tools, agents, and environments.
This design allows AI-driven workflows to reason about MCP itself — enabling use cases such as protocol education, implementation guidance, validation, and documentation support — all grounded in the canonical source of truth.
