@seashail/mcp

Run the Seashail MCP server in one line via npx. This is a thin wrapper that ensures seashail is installed and runs seashail mcp for you.

See the main README for full project documentation, or the Install docs for all installation methods.

Usage

npx -y @seashail/mcp

Pass through args to seashail mcp:

npx -y @seashail/mcp -- --network testnet

Use in Agent MCP Config

If you don't want to install the seashail binary globally, reference this package in your agent's MCP config instead:

{
  "mcpServers": {
    "seashail": {
      "command": "npx",
      "args": ["-y", "@seashail/mcp", "--"]
    }
  }
}

Testnet:

{
  "mcpServers": {
    "seashail-testnet": {
      "command": "npx",
      "args": ["-y", "@seashail/mcp", "--", "--network", "testnet"]
    }
  }
}

How It Works

• If seashail is already installed, the wrapper runs it directly
• If seashail is not installed, the wrapper executes the hosted installer:
  • macOS/Linux: curl -fsSL https://seashail.com/install | sh
  • Windows (PowerShell): irm https://seashail.com/install.ps1 | iex
• After installation, it runs seashail mcp with any provided args

Alternatives

• Direct install (recommended): curl -fsSL https://seashail.com/install | sh — see Install docs
• Python wrapper: uvx seashail-mcp — see python/
• One-click agent templates: seashail agent install <target> — see Agent Integration
