mcp-spec

name	mcp-spec
description	Router skill for the Model Context Protocol (MCP) open spec, covering the protocol itself (JSON-RPC framing, capabilities, lifecycle), the client and server roles, the transport layers (stdio / streamable HTTP / SSE), and the core primitives (tools, resources, prompts, sampling, roots, completion). Use when the user asks about: writing an MCP server (in any language), writing an MCP client, the JSON-RPC protocol framing, the initialize handshake, capability negotiation, the stdio transport, the streamable HTTP transport, the SSE transport, defining a tool / resource / prompt, sampling, roots, or completion. Includes the TypeScript SDK (`@modelcontextprotocol/sdk`) and Python SDK (`mcp`). Skip: Anthropic's hosted MCP connector (use anthropic-platform-features), the user-facing Claude Connectors directory (use claude-connectors), Claude Code's `.mcp.json` config (use claude-code → SKILL-mcp).

This skill is auto-updated daily. A pipeline reads the upstream docs and rewrites the per-surface files below. Section structure is stable; content drifts to track upstream.

Dispatch table

Surface file	Read when the user asks about…
SKILL-protocol.md	JSON-RPC framing, the initialize handshake, capability negotiation, lifecycle, error codes, versioning
SKILL-clients.md	implementing an MCP client, calling tools, reading resources, the client-side of sampling
SKILL-servers.md	implementing an MCP server in TypeScript or Python, server-side capability advertisement, server lifecycle
SKILL-transport.md	stdio transport, streamable HTTP transport, SSE transport (legacy), choosing a transport
SKILL-tools-resources-prompts.md	defining tools (input schema, output schema), defining resources (URI templates, MIME types), defining prompts, sampling, roots, completion
