Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.

saschb2bSkillsaschb2b/skills/skills/engineering/mcp-server/SKILL.md
Build, extend, and maintain a Model Context Protocol (MCP) server across its whole lifecycle against the current spec and official SDKs. Covers the architecture, choosing a transport (stdio vs Streamable HTTP), writing tool definitions agents actually use, adding tools without breaking existing agents, versioning and deprecation, the security threat model (tool poisoning, token passthrough, prompt injection, OAuth), testing with the MCP Inspector, and publishing to the registry. Use when building an MCP server, exposing a CLI, API, or app to AI agents (Claude Code, Cursor, Cline, Windsurf), adding or reviewing MCP tools, fixing an agent that calls the wrong tool or loads too many, securing or authorizing an MCP server, migrating transports, or shipping and versioning one. Also for any new agent-tool integration where the target has a scripting API, CLI, or HTTP surface.

Specification for building Model Context Protocol servers using Python
AnthropicSkillanthropics/claude-plugins-official/plugins/mcp-server-dev/skills/build-mcp-server/SKILL.md
This skill should be used when the user asks to "build an MCP server", "create an MCP", "make an MCP integration", "wrap an API for Claude", "expose tools to Claude", "make an MCP app", or discusses building something with the Model Context Protocol. It is the entry point for MCP server development — it interrogates the user about their use case, determines the right deployment model (remote HTTP, MCPB, local stdio), picks a tool-design pattern, and hands off to specialized skills.
affaan-mSkillaffaan-m/ECC/.agents/skills/mcp-server-patterns/SKILL.md
Build MCP servers with Node/TypeScript SDK — tools, resources, prompts, Zod validation, stdio vs Streamable HTTP. Use Context7 or official MCP docs for latest API. Use when building or debugging an MCP server — tools, resources, prompts, validation, or transport choice.
affaan-mSkillaffaan-m/ECC/.cursor/skills/mcp-server-patterns/SKILL.md
Build MCP servers with Node/TypeScript SDK — tools, resources, prompts, Zod validation, stdio vs Streamable HTTP. Use Context7 or official MCP docs for latest API.
aws-samplesSkillaws-samples/sample-apex-skills/skills/eks-mcp-server/SKILL.md
Install, configure, and troubleshoot the EKS MCP Server connection in your AI assistant (Claude Code, Cursor, Kiro). Use ONLY for MCP server setup problems — config file location (.mcp.json), IAM permissions for eks-mcp actions, uvx installation, choosing AWS-hosted vs self-hosted mode, or debugging why MCP tools fail to appear after config. Also activate if user mentions "eks mcp", "mcp server", "mcp.json", or "mcp tools not showing". Do NOT use for actual cluster operations once MCP is working — those go to eks-recon (discovery), eks-operation-review (audits), or eks-upgrade-check (upgrades). For setting up the Arm migration MCP server used for arm64 readiness scanning, use graviton-migration, not this skill.
OneWave-AISkillOneWave-AI/claude-skills/mcp-server-builder/SKILL.md
Use to build, wire up, or debug an MCP (Model Context Protocol) server that gives Claude access to an internal API, database, or SaaS tool. Trigger when the user wants Claude to connect to their own system, asks for an MCP server, needs custom tools for Claude Code or the Claude app, or an existing server's tools are not showing up.
apollographqlSkillapollographql/skills/skills/apollo-mcp-server/SKILL.md
Guide for using Apollo MCP Server to connect AI agents with GraphQL APIs. Use this skill when: (1) setting up or configuring Apollo MCP Server, (2) defining MCP tools from GraphQL operations, (3) using introspection tools (introspect, search, validate, execute), (4) troubleshooting MCP server connectivity or tool execution issues.
MicrosoftSkillmicrosoft/mcp-interactiveUI-samples/mcp-apps/zava-insurance/node/src/mcpserver/SKILL.md
Migrates an MCP server with interactive widgets from the OpenAI Apps SDK (window.openai, text/html+skybridge) to the MCP Apps standard (@modelcontextprotocol/ext-apps), covering server-side and client-side changes.
standardbeagleSkillstandardbeagle/lci-cpp/.agents/skills/lci-mcp-server/SKILL.md
Use when: working on `lci mcp` stdio transport, JSON-RPC framing/version negotiation, tools/list schema emit, add_tool/unknown-param guard, MCP error conventions, the HTTP /mcp bridge, info/index_stats/debug_info tools, tool-surface.json drift, or comparing lci's MCP layer to other code MCP servers.
GitHubSkillgithub/awesome-copilot/skills/go-mcp-server-generator/SKILL.md
Generate a complete Go MCP server project with proper structure, dependencies, and implementation using the official github.com/modelcontextprotocol/go-sdk.
forefySkillforefy/.context/skills/llms/mcp-server-pentest/SKILL.md
Pentest an MCP server for authentication bypass, confused-deputy SSRF, and tool-argument injection - black-box from its URL, deeper with repo or host access. Use to assess an MCP server's exposure.
backnotpropSkillbacknotprop/build-mcp-server/skills/build-mcp-server/SKILL.md
Design, scaffold, audit, and upgrade Model Context Protocol servers. Use when the user asks to build or migrate an MCP server, adopt MCP 2026-07-28, add dual-era support, create an MCP integration, expose an API or data source through MCP tools/resources/prompts, add OAuth or API-key auth to an MCP endpoint, run an authorization server for it, support browser-hosted MCP clients, or choose an MCP transport/auth/deployment shape.
HK-hubSkillHK-hub/AgentSkills/build-mcp-server/SKILL.md
This skill should be used when the user asks to "build an MCP server", "create an MCP", "make an MCP integration", "wrap an API for Claude", "expose tools to Claude", "make an MCP app", or discusses building something with the Model Context Protocol. It is the entry point for MCP server development — it interrogates the user about their use case, determines the right deployment model (remote HTTP, MCPB, local stdio), picks a tool-design pattern, and hands off to specialized skills.
DoiiarXSkillDoiiarX/claude-skills/server-md/SKILL.md
管理个人 SERVER.md 运维知识库。Use this skill whenever the user mentions ~/SERVER.md, SERVER.md, 服务器清单, server inventory, tailnet nodes, self-managed servers, WSL/Windows/Ubuntu host notes, or asks Claude to create, locate, update, summarize, or use a personal server runbook. It helps Claude find the canonical SERVER.md across WSL, Windows, native Ubuntu, and remote hosts; preserve progressive disclosure by splitting details into reference files; summarize local machine and managed servers without leaking secrets; and turn server notes into safe operational checklists.
Hassaan146SkillHassaan146/claude-skills/mcp-server-builder/SKILL.md
Design and ship production-ready MCP (Model Context Protocol) servers from OpenAPI contracts instead of hand-written tool wrappers. Python and TypeScript support, schema validation, safe evolution. Use when exposing an existing API as an MCP server, building tool integrations for Claude or Codex or Cursor, or scaffolding an MCP project from scratch.
asgard-ai-platformSkillasgard-ai-platform/skills/tech-mcp-server-dev/SKILL.md
Build MCP (Model Context Protocol) servers including tool definition, schema design, authentication, error handling, and Claude Code integration. Use this skill when the user needs to create an MCP server, expose APIs or databases to AI agents, design tool schemas, or integrate with Claude Code — even if they say 'build an MCP server', 'connect Claude to our database', 'expose our API to AI', or 'create a tool for Claude Code'.
tae0ySkilltae0y/python-project-template/.claude/skills.nouse/python-mcp-server/SKILL.md
Instructions for building Model Context Protocol (MCP) servers using the Python SDK. Provides patterns, best practices, and code examples for FastMCP, tools, resources, prompts, and transports.
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
