Cloud AI cost notice

Bring your own API keys, bring your own spending controls.

SwarmMarshal is free during public preview, but cloud LLM providers bill the API keys you add. You are solely responsible for any OpenAI, Anthropic, Google, xAI, DeepSeek, Hugging Face, or other provider charges. Agent loops, retries, long conversations, inbox backfills, large attachments, or misconfigured routes can cause runaway token usage. Set hard spending caps and alerts with each provider before enabling cloud models, and monitor SwarmMarshal's LLM call history while agents run.

Windows · PowerShell

One-line install

iwr -useb https://swarmmarshal.com/install.ps1 | iex

Pulls the release manifest, installs, creates a swarmmarshal launcher, opens the app. Cloud LLM API usage is billed by your provider, so set provider-side caps before adding keys.

macOS · Terminal

One-line install

curl -fsSL --proto '=https' --tlsv1.2 https://swarmmarshal.com/install.sh | bash

The installer downloads the signed macOS package from the manifest, places SwarmMarshal.app in Applications, and opens it. Apple Messages sync uses Full Disk Access for that stable app path. You remain responsible for cloud LLM charges from keys you configure.

PasteBuddy · Windows

One-line install

iwr -useb https://swarmmarshal.com/pastebuddy-install.ps1 | iex

Pulls the PasteBuddy release manifest, verifies the installer checksum, and runs the Windows setup package.

PasteBuddy · macOS

One-line install

curl -fsSL --proto '=https' --tlsv1.2 https://swarmmarshal.com/pastebuddy-install.sh | bash

Downloads the PasteBuddy DMG from the manifest, verifies the checksum, installs PasteBuddy.app in Applications, and opens it.

Connect mail

Gmail and Outlook need a one-time OAuth setup.

SwarmMarshal is local-first — Google and Microsoft want you to register your own app for direct mailbox access. Both walkthroughs are roughly ten minutes.

Wire it to your agent

Plug SwarmMarshal into Claude Code or Codex as an MCP server.

Once your accounts are connected, point your MCP-aware client at the bundled SwarmMarshal.McpServer. Your agent gets ~40 typed tools — context packs, thread and person history, search, compose, and act — across every inbox at once.

Claude Code

Add to mcp.json

{
  "mcpServers": {
    "swarmmarshal": {
      "command": "SwarmMarshal.McpServer"
    }
  }
}

The installer puts SwarmMarshal.McpServer on your PATH. Set SwarmMarshal_DATA_DIR in env if you use a non-default profile.

Codex CLI

Add to Codex config

{
  "mcp": {
    "servers": {
      "swarmmarshal": { "command": "SwarmMarshal.McpServer" }
    }
  }
}

Codex launches the binary on stdio and discovers the tool catalog on handshake. No keys, no HTTP, no remote service.
