Use an MCP server when Claude Code needs to reach an external tool or data source; use a Claude Code plugin when you want to package and distribute one or more Claude Code components together. They solve different problems, and you can use both: a plugin can include an MCP server.
What is the difference between an MCP server and a plugin?
MCP is an open-source standard for connecting AI applications to tools and data. In Claude Code, an MCP server provides access to external services such as issue trackers, monitoring systems, databases, design systems, or workflow automation. See Anthropic’s Claude Code MCP guide.
A Claude Code plugin is a package that installs and loads components together. The documented components include skills, subagents, hooks, MCP servers, and other extensions. A plugin is therefore a packaging and distribution layer; an MCP server is the integration that exposes external tools. A plugin may bundle that integration. See the Claude Code Plugins overview.
Which one should you choose?
| Your need | Choose | Why |
|---|---|---|
| Connect Claude Code to an external API, database, or service | MCP server | Its role is to expose external tools and data to Claude Code. |
| Install a skill, subagent, hook, or group of extensions together | Plugin | A plugin packages components as one installable unit. |
| Share a consistent collection of Claude Code extensions with a team | Plugin | Plugins can be distributed through marketplaces or folders. Collaborators install them on their own machines. |
| Share only an MCP connection through a repository | Project-scoped MCP configuration | Project scope can share server configuration through .mcp.json; users must approve project servers before use. |
| Bundle extensions with access to a service | A plugin containing an MCP server | The plugin handles packaging while its MCP server supplies the external connection. |
| Set up one private server for one project | Standalone MCP configuration | There is no need to create a plugin solely to wrap a single connection. |
How scope and distribution differ
MCP server configuration
Claude Code supports local, project, and user scopes for MCP servers. Project scope is suited to shared repository configuration and uses .mcp.json; Claude Code asks users to approve a project-scoped server before it is used. Local and user scopes cover private project or cross-project setups. The MCP guide documents connection configuration and scope options: Connect Claude Code to tools via MCP.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Plugin installation
Plugins also support local, project, and user installation scopes. A project can commit plugin settings in .claude/settings.json so repository collaborators can use the setup, but each collaborator installs the plugin on their own machine. Plugins can be installed from a marketplace or folder; marketplaces list plugins and their locations. Refer to the plugin documentation for current installation details.
Transport, runtime, and context considerations
Choose a suitable MCP transport
Anthropic’s current MCP guide recommends remote HTTP servers where available. It marks SSE as deprecated and recommends HTTP where supported; SSE-only services remain documented. Local stdio servers run as local processes and are described as suitable for direct system access or custom scripts. Transport guidance can change, so check the current MCP guide when setting up a connection.

Consider what runs in a session
Enabled plugin components can affect session context and activity. The plugin guide says names and descriptions for invocable skills, agents, and commands are available in context on each turn; plugin MCP servers run alongside enabled sessions, and hooks run at their configured events. Inspect a plugin’s footprint and disable components you do not use, as described in the Plugins overview.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Review security before enabling either option
Evaluate the access granted, not just the packaging format. Anthropic warns that MCP servers fetching external content can expose users to prompt injection. It also says plugins run with the user’s privileges, so their code and hooks deserve review before installation. A marketplace listing does not replace checking the plugin itself.
