  • Installs and runs third-party packages from npm and PyPI
  • Edits the client config and launches arbitrary MCP servers

This is third-party code. Review the repository files before installing.

What it does

The installer runs as an MCP server: you connect it to a client and then ask the agent to install the server you want. It installs servers from npm and PyPI, accepts launch arguments and environment variables, and writes them into the client config. It can also wire up local servers by a path on disk. Node servers need npx, Python servers need uv.

Who it is for. For people who add MCP servers often and would rather not edit the config by hand.

Good fit when

  • You want to quickly add an MCP server from npm or PyPI
  • You need to install a local MCP server by its path on disk
  • You want the agent to write the server into the config itself

Not a fit when

  • You only need one specific server that is easier to add by hand
  • The machine has neither npx nor uv

Example request

Install the server-filesystem MCP server and pass it the path to my working folder

MCP

Transport
stdio
Authentication
not required

Limitations

The repository has not been updated in a long time and newer clients may use a different config schema, so some flows can fail without adjustments. It needs npx and uv. The installer runs third-party packages, so install only trusted sources.

How to disable. Remove the mcp-installer block from your client's MCP config and restart the client.

FAQ

What is needed besides the installer itself?

npx for Node servers and uv for Python ones.

Where does it install servers from?

From npm and PyPI, and locally by a given path on disk.

README in short

The README explains this is an MCP server that installs other MCP servers. You add it to the client config via the npx command with the @anaisbetts/mcp-installer package, then ask the agent to install a server from npm or PyPI. The examples show how to pass arguments and environment variables and how to add a server by a local path. Node servers require npx, Python servers require uv.
