Installer MCP Server
Automate the installation of npm and PyPi-based MCP servers directly via chat prompts.
Data last scanned today · Reviewed today
Overview
This server streamlines your environment management by enabling AI assistants to install new MCP servers on demand. It acts as a bridge to `npx` and `uv`, allowing you to add node or Python packages to your configuration without manually editing files. To use it, configure the server in your Claude desktop settings. Once active, you can provide prompts to install specific packages, point to local directory paths, or define environment variables required for the new servers to operate.
Our verdict
This tool carries a high risk level with a security score of 28/100. The repository has not been updated in over 600 days, and it is maintained by a single contributor rather than an official vendor, meaning there is no ongoing security oversight or recent patches. Because this server executes installation commands on your local machine, it is best suited for experimental sandbox environments rather than sensitive production workstations.
- Supports installation from npm and PyPi repositories
- Requires only three direct dependencies
- Simplifies adding servers via conversational prompts
- Last commit was 608 days ago
- High risk due to lack of recent security maintenance
- Single contributor presents a high bus-factor risk
Setup
{
"mcpServers": {
"mcp-installer": {
"args": [

}
}
}Paste into ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Some servers require API keys or tokens as environment variables — check the project's README and add an "env" object if needed.
- No read-only mode — running this grants full read/write access.
- No built-in authentication — anyone with access to this config can invoke every tool it exposes.
