Cline MCP

What the Cline MCP Marketplace is

The Cline MCP Marketplace is an in-product catalogue that lets you browse and install protocol servers for the Cline coding agent with one click, covering file systems, databases, cloud platforms, browsers and design tools. It is a distribution channel rather than a server itself.

What it does

You open the marketplace inside the extension, search or filter by category, and install a server so the agent gains new capabilities. Listings show a description, author, install count and tags. The loop is browse, install, use.

Categories span databases, cloud platforms, browser automation, version control, knowledge and memory, search, and communication, and authors can submit their own servers for inclusion. Servers can only be installed through the extension, so the marketplace is a preview surface rather than a standalone site.

Who it is for

It is aimed at developers using the extension who want to add tool access without hand-editing configuration files, and at teams standardising which servers their engineers may install. Removing the configuration step is the whole value proposition.

What to keep in mind

Browsing and installing are free, so confirm whether any listed server charges separately for its own service, because the marketplace and the service behind a server are different commercial arrangements.

The central caution applies to this whole category. Many servers here request filesystem, shell, database or cloud access, and install counts and tags say nothing about code quality or intent. Popularity measures adoption, and adoption is not review.

One-click install also means one-click permission grants. Read what you are approving rather than clicking through the prompts, because the moment of installation is the moment the access is decided and it is rarely revisited afterwards.

Review the upstream source before installing, prefer read-only or scoped credentials, and be especially careful with servers that can execute code or read local files, since those combine the broadest reach with the least visibility. Treat third-party servers as untrusted until you have looked at them. It is worth deciding as a team what the marketplace policy is, because one-click installation makes a governance question look like a convenience feature. A short list of approved servers, a rule that new ones start read-only, and a named person who reviews additions will limit exposure more than any amount of caution applied individually. The installation moment is also when permissions are granted, and permissions are rarely revisited on a server everyone has been using for months. If your editor already runs with broad local access, assume an installed server inherits it. Reviewing the upstream source before installation remains the cheapest control available, and it is the one most often skipped because the install button is right there.
