A CLI tool to install and manage MCP servers.
npm install install-mcpInstalling MCPs is a huge pain, so I made a CLI tool to make it easier.
The CLI now supports multiple installation methods with automatic detection:
``bash`
npx install-mcp mcp-package-name --client claude
`bash`
npx install-mcp @org/mcp-server --client claude
`bash`
npx install-mcp 'npx some-mcp-server --custom-args' --client claude
`bash`
npx install-mcp https://mcp.example.com/server --client claude
The tool automatically:
- Converts simple package names to npx package-namemcp.example.com
- Preserves full commands as-is
- Infers server names from package names or URLs (e.g., → mcp-example-com)
- Handles OAuth authentication for remote servers
When installing a server hosted on https://api.supermemory.ai/*, you can pass a project name via --project. This is a convenience alias for adding the header x-sm-project: .
Rules:
- Only applies to URL installs targeting https://api.supermemory.ai/*.--project
- Values must not contain spaces.
- If you omit for these URLs, you'll be prompted. Pressing Enter uses default.--header
- The value is injected as a header alongside any flags.
Examples:
`bashExplicit project
npx install-mcp https://api.supermemory.ai/servers/my-server \
--client cursor \
--project myproj
Warp users: the generated config will include
--header "x-sm-project: in the args array when installing Supermemory URLs.$3
You can pass headers for authentication or other purposes using the
--header flag:`bash
Single header
npx install-mcp https://api.example.com/mcp --client claude --header "Authorization: Bearer token123"Multiple headers
npx install-mcp https://api.example.com/mcp --client claude \
--header "Authorization: Bearer token123" \
--header "X-API-Key: secret-key"
`$3
When installing remote servers (URLs), the CLI will ask if the server uses OAuth authentication:
`bash
npx install-mcp https://api.example.com/mcp --client claude
Output: Does this server use OAuth authentication? (Y/n)
`You can bypass this prompt using the
--oauth flag:`bash
Automatically run OAuth authentication
npx install-mcp https://api.example.com/mcp --client claude --oauth yesSkip OAuth authentication entirely
npx install-mcp https://api.example.com/mcp --client claude --oauth no
`If you answer yes, the authentication flow:
- Runs automatically before installation
- Handles OAuth flows seamlessly in the background
- Authentication state is shared globally - once you authenticate with a server, that authentication is automatically available to all MCP clients
- No need to re-authenticate when using the same server in different clients
`bash
Output: Running authentication for https://api.example.com/mcp
`If authentication fails, you'll see:
`
Authentication failed. Use the client to authenticate.
`If the server doesn't use OAuth (you answer no), the installation proceeds directly without authentication.
This ensures secure access to remote servers while maintaining flexibility for servers that don't require OAuth.
