Harbor ships with a curated catalog of native MCP servers — pre-configured with the right commands, arguments, and authentication. Dock them with a single command or click.

CLI Usage

Examples:

Desktop Usage

Open the Scout page and browse the Native Fleet grid. Click Dock, Charter (OAuth), or Add Key (API key) depending on the server.

Catalog

Remote Servers (HTTP)

These connect to vendor-hosted MCP endpoints over HTTP. No local process is spawned.

Local Servers (stdio)

These run as local processes on your machine.

Authentication

OAuth servers

When you dock an OAuth server for the first time, Harbor opens your browser to authorize. Tokens are stored securely in the vault and refreshed automatically.
Use --skip-auth to dock now and authorize later:

API Key servers

Servers that need a manual token require you to store the key in the vault first:

No-auth servers

These work out of the box:

Extra Arguments

Some servers accept extra arguments appended after the defaults. Use -- to separate them:
