Best MCP Skills for Claude Code
Skills for the Model Context Protocol — the layer that gives an agent callable tools instead of more prose to read. The list below mixes three kinds, and the difference is the whole point: skills for building MCP servers (mcp-developer, mcp-builder), a skill that operates a shipped MCP integration (atlassian-mcp for Jira and Confluence), and a skill that drives an MCP server to do ordinary work (browser-testing-with-devtools against Chrome DevTools). Every entry is scored on the same six-dimension rubric, security dimension included.
Integrates with Atlassian products to manage project tracking and documentation via MCP protocol.…
Strong integration skill with probe-before-write workflow, MUST/MUST-NOT guards, and exemplary token-handling patterns; description lacks When-Not, official-server install command likely inaccurate.
Use when building, debugging, or extending MCP servers or clients that connect AI systems with ex…
Strong MCP implementation skill with explicit test-feedback loop via inspector, dual-language runnable templates, and five scoped references; description still lacks When-Not boundary.
Tests in real browsers via Chrome DevTools MCP. Use when building or debugging anything that runs…
Excellent browser-testing skill with three structured debugging workflows, a test-plan template, and an unusually strong security section covering profile isolation, untrusted-content rules, and JS execution constraints.
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact…
Solid four-phase MCP server development guide with per-language references and a working evaluation harness; description is thin on trigger variants and When-Not, and style is emoji-heavy.
Guides users through setting up an ElevenLabs API key for ElevenLabs MCP tools. Use when the user…
Excellent interactive setup guide: checks existing key first, validates against the official endpoint with a bounded retry, and writes cleanly to .env; trigger description covers failure-driven scenarios well.

FAQ
What is an MCP skill for Claude Code?
Two different things, and the distinction decides which one you want. A skill can help you build an MCP server — scaffolding, tool schemas, transport, error handling — or it can use an MCP integration that already exists to get work done. mcp-developer and mcp-builder are the first kind; atlassian-mcp is the second.
Should I build an MCP server or a skill?
If the capability is something the agent calls — an API, a database, a service it should act on — an MCP server is the right shape: it exposes typed, callable tools rather than instructions the model has to interpret. If the capability is knowledge or judgment — how to review a contract, how to structure a deck — a SKILL.md package is the right shape and a server would be over-engineering. mcp-builder walks that decision before it writes any code.
Do MCP servers change the security picture?
They widen it. A server you install is a capability surface: it can read and act on whatever its scope allows, and the permission prompt is the only thing between a tool call and your data. The skills here are scored on the same security dimension as everything else — capability manifest compared against what the description promises — and that is the check that catches an integration reaching for more than it advertises.
Why is a browser-testing skill on an MCP page?
Because it is a working example rather than a demo: browser-testing-with-devtools drives a real browser through the Chrome DevTools MCP server inside a normal testing workflow. If you want to see what an MCP integration feels like when it is load-bearing, start there.
