Use with AI agents

Marrow is MCP-native. The fastest way to add it is the one-command setup:

npx -y marrow-setup --email you@example.com

What it does

• Issues a free API key to your email (no card, idempotent)
• Detects your agents and writes the MCP server config — JSON / TOML / CLI auto-detected per client
• Backs up existing config (.marrow.bak) — nothing breaks, re-runs don’t duplicate
• Adds the Marrow skill (scout→read, change tracking, monitoring)
• Runs via npx — nothing installed globally

Manual setup

Claude Code

claude mcp add marrow \
  -e MARROW_API_KEY=mrw_xxx \
  -- npx -y @marrowdev/mcp

Cursor / Claude Desktop / VS Code

{
  "mcpServers": {
    "marrow": {
      "command": "npx",
      "args": ["-y", "@marrowdev/mcp"],
      "env": { "MARROW_API_KEY": "mrw_xxx" }
    }
  }
}

Codex

~/.codex/config.toml

[mcp_servers.marrow]
command = "npx"
args = ["-y", "@marrowdev/mcp"]
env = { MARROW_API_KEY = "mrw_xxx" }

Tools

marrow_scout · marrow_read (+ changeTracking: true) · marrow_search · marrow_crawl · marrow_screenshot · marrow_monitor_create / marrow_monitor_list / marrow_monitor_run

The Marrow skill

The setup also installs a skill that teaches your agent Marrow’s three moves:

1. scout → read — get content efficiently
2. “what changed?” → marrow_read(url, changeTracking: true)
3. “watch this” / “do my rounds” → the monitor tools

So you can just talk to your agent (“do today’s rounds — only tell me what changed”) instead of remembering tool names.
