YOUR AGENT, IN YOUR ASSISTANT

Your Merryman,
in Claude.

Ask about its trades, your portfolio and the market in plain words. Your assistant only gets what you allow, and it can never move your money.

Add to Claude

Add to Claude (opens in a new tab)
  1. Claude opens with Merrymen already filled in. Click Continue, then Connect.
  2. Merrymen opens. Sign in if asked, then click Allow.
  3. Back in Claude, ask “Why hasn’t my agent traded?”

Add it once and it works on claude.ai and in the Claude desktop and mobile apps. Claude Code signed in to the same account gets it too.

On a Team or Enterprise plan? Your organisation’s owner adds it once: add Merrymen for your organisation (opens in a new tab). Everyone else then finds Merrymen in Claude under Customize → Connectors and clicks Connect. Claude’s free plan allows one custom connector.

Other assistants

  • Claude Code

    In Claude Code, run these one at a time:

    /plugin marketplace add https://github.com/millw14/merrymen.git
    /plugin install merrymen@merrymen

    Then type /mcp, choose Merrymen and Authenticate. You get /merrymen:status, /merrymen:why, /merrymen:portfolio and more, or just ask.

    Added Merrymen to Claude already? Claude Code signed in to the same account has it too. Without the plugin, from a terminal:

    claude mcp add --transport http --scope user merrymen https://mcp.merrymen.dev/mcp
claude mcp login merrymen

    Or just tell Claude Code:

    Set up the Merrymen MCP server. Instructions: https://merrymen.dev/llms.txt

Good to know

  • Claude asks before each action. To stop it asking for read-only look-ups, open Claude → Customize → Connectors → Merrymen and set Read-only tools to Always allow.
  • It only sees the agent and permissions you allow when you connect. Disconnect it any time on Connected apps.
  • It can suggest trades or setting changes only if you allow that, and nothing happens until you approve them in Merrymen.
  • It can never move your funds, see your keys, turn on live trading or loosen your limits.
  • Paper (practice) results are always kept apart from real money.

For AI assistants

  • Claude Code: run claude mcp list first; an entry at https://mcp.merrymen.dev/mcp means it is already set up. Otherwise run claude mcp add --transport http --scope user merrymen https://mcp.merrymen.dev/mcp, then ask the user to type /mcp, choose Merrymen and Authenticate (do not run claude mcp login yourself). No API key or token is needed; never ask for one.
  • claude.ai, Claude Desktop or Claude mobile: you cannot add it from a chat. Give the user the Add to Claude link (opens in a new tab).
