First-party implementation stance
createskills treats skills as transparent files and MCP as a retrieval channel for saved sources, not as interchangeable labels.

Claude Skills vs MCP
Claude Skills vs MCP: when to use each
Skills package reusable instructions and references. MCP connects agents to tools, data, and source libraries at runtime.
Direct answer
Use Claude Skills for repeatable workflows and file-based instructions; use MCP when an agent needs to query tools, data, or saved sources during work. Many serious agent setups need both.

Comparison
| Criteria | Claude Skills | MCP |
|---|---|---|
| Best job | Reusable workflow instructions, examples, and reference folders. | Runtime access to tools, data, APIs, and hosted source libraries. |
| Context shape | Plain files such as SKILL.md, references/, scripts/, and assets/. | Server-exposed tools and resources the agent can call when needed. |
| Setup burden | Mostly file authoring and placement in the target agent environment. | Requires server configuration, auth, transport, and tool permissions. |
| Risk | Poor triggers or unsafe bundled scripts can steer work incorrectly. | Overbroad tools or credentials can expose data and actions. |
| Where createskills fits | Generates source-backed SKILL.md packages and references. | Exposes saved captures through hosted source-library retrieval. |
Skills and MCP solve different parts of agent context. Skills tell the agent how to work; MCP lets the agent retrieve or act on the right context while working.
The practical distinction
A Skill is a packaged capability. MCP is a connection layer. If the job is "review landing pages in our house style," a skill can hold the workflow. If the job is "find the latest saved customer calls and use them," MCP is the retrieval path.
Use both when context changes
Static instructions belong in SKILL.md. Changing source material belongs in a library or tool the agent can query. createskills supports both: source-backed skill folders and a hosted MCP source library.
Security model
Skills are easiest to inspect when they are plain Markdown and references. MCP needs tighter permission thinking because it can expose live tools or account data. Keep both scoped to the work they should influence.
Evidence
Proof and limitations
Workflow
Decision workflow
- 1Write the reusable instructions as a skill when the workflow repeats.
- 2Put long or changing source material in references or a source library.
- 3Use MCP when the agent needs to search or fetch sources during the task.
- 4Ask the agent to name the skill and sources it used.
Decision rule
Use a Skill when the agent needs a repeatable operating procedure.
Use MCP when the agent needs runtime access to saved sources or tools.
Use both when the procedure is stable but the source library changes.FAQ
Questions people ask
Is MCP a replacement for Claude Skills?
No. MCP connects tools and data. Skills package task instructions and references. They are complementary.
Which should I implement first?
Start with the bottleneck. If instructions are inconsistent, build a skill. If source retrieval is painful, connect MCP.
Can createskills generate both?
createskills can prepare source-backed skill packages and expose saved captures through its hosted MCP server.
