Install

Recommended: Install The seashail Binary

Seashail is a local binary. Your agent runs it as an MCP stdio server (via seashail mcp).

You need:

• git
• cargo (Rust toolchain)

macOS / Linux

curl -fsSL https://seashail.com/install | sh

If seashail is not found after install, add the default install dir to your shell PATH:

export PATH="$HOME/.local/bin:$PATH"

Windows (PowerShell)

If you have WSL, you can run the macOS/Linux installer inside WSL.

Otherwise, install with PowerShell (source build):

irm https://seashail.com/install.ps1 | iex

If seashail is not found after install, add the default install dir to your PATH for the current session:

$env:Path = "$HOME\.local\bin;$env:Path"

No-Install Options

If you don't want to install the seashail binary, you can reference these wrappers in your agent's MCP config instead. They install and run Seashail automatically.

npx (Node.js)

Use this as your MCP server command:

• Command: npx
• Args: -y @seashail/mcp --

Testnet:

• Args: -y @seashail/mcp -- --network testnet

uvx (Python)

Use this as your MCP server command:

• Command: uvx
• Args: seashail-mcp

Testnet:

• Args: seashail-mcp -- --network testnet

These wrappers call seashail mcp under the hood. If seashail is already installed, they will use it; otherwise they run the hosted installer (source build).

OpenClaw Users

If you use OpenClaw, install Seashail as a native plugin:

seashail openclaw install

Or via the OpenClaw CLI directly:

openclaw plugins install @seashail/seashail
openclaw plugins enable seashail
openclaw gateway restart

See the OpenClaw setup guide for full details.

Verify Installation

After installing, verify the binary is working correctly:

seashail doctor

This checks for common issues (missing dependencies, permissions, path configuration). For detailed diagnostics, see the CLI reference.

Build From Source (Dev)

If you are hacking on the repo:

bun install
bun run check

cargo build -p seashail

The binary will be at:

./target/debug/seashail

To use the dev binary with your agent, point your agent config to:

• Command: ./target/debug/seashail
• Args: mcp

You can also print the resolved config and data paths:

./target/debug/seashail paths

Next Steps

• Connect Your Agent — Set up Claude Desktop, Cursor, VS Code, OpenClaw, and more
• Quickstart — Create your first wallet and start trading
• Configuration — Customize paths, network mode, and RPC endpoints

Notes

• Seashail is non-custodial: if you lose your passphrase and/or recovery share(s), funds can be permanently unrecoverable.
• Transactions are irreversible.
