MCP server - Market or Die

The Market or Die MCP server lets an AI assistant act on your workspace — list channels, draft, schedule, and publish posts, and read the leaderboard. There are two ways to connect:

Remote (recommended)

A hosted server at a single URL. Sign in with your Market or Die account — no API key to manage. Best for Claude, ChatGPT, and Cursor.

Local (npm)

Runs on your machine via npx and authenticates with an API key. Use it for offline clients or when you’d rather not use OAuth.

Remote server (OAuth)

Point your client at:

https://api.marketordie.io/mcp

The first time you connect, your browser opens a Market or Die sign-in and consent screen. Approve it once and the client stays connected — tokens refresh automatically. Authorization uses OAuth 2.1 with dynamic client registration, so there’s nothing to paste.

Open connectors

In Claude, go to Settings → Connectors → Add custom connector.

Add the URL

Name it Market or Die and set the URL to https://api.marketordie.io/mcp. Save.

Click Connect. A Market or Die window opens — sign in and Authorize. You’ll bounce back to Claude, connected.

Open connectors

In ChatGPT, go to Settings → Connectors → Create (Developer mode / custom MCP must be enabled on your plan).

Add the URL

Set the MCP server URL to https://api.marketordie.io/mcp and choose OAuth for authentication.

Connect, then sign in to Market or Die and Authorize.

Add this to ~/.cursor/mcp.json (or Settings → MCP → Add server), then click Login next to the server when Cursor prompts:

{
  "mcpServers": {
    "marketordie": {
      "url": "https://api.marketordie.io/mcp"
    }
  }
}

Any client that supports remote MCP over Streamable HTTP with OAuth works. Use the server URL https://api.marketordie.io/mcp; the client handles registration and login automatically.

{
  "mcpServers": {
    "marketordie": {
      "url": "https://api.marketordie.io/mcp"
    }
  }
}

Local server (npm)

Prefer a key over the browser flow? The local server wraps the same REST API. First create an API key under Profile → Developers, then add:

{
  "mcpServers": {
    "marketordie": {
      "command": "npx",
      "args": ["-y", "marketordie-mcp"],
      "env": { "MARKETORDIE_API_KEY": "mod_live_…" }
    }
  }
}

Variable	Required	Default
`MARKETORDIE_API_KEY`	yes	—
`MARKETORDIE_BASE_URL`	no	`https://api.marketordie.io/v1`

Tools

Both servers expose the same tools:

Tool	What it does
`whoami`	Current workspace and member.
`list_channels`	Connected accounts (use their ids in `create_post`).
`create_post`	Publish now, schedule, or save a draft to one or more channels.
`list_posts`	List posts; filter by status, paginate.
`get_post`	Fetch one post.
`delete_post`	Delete a draft or scheduled post.
`get_leaderboard`	Team standings by points.

Try it

Once connected, ask your assistant things like:

“What channels can I post to in Market or Die?”
“Draft a LinkedIn post announcing our new pricing.”
“Schedule this thread to X and LinkedIn for tomorrow 9am.”
“Show my scheduled posts.”

Troubleshooting

The sign-in window doesn't open

Authorized but no tools show up

Restart the client after connecting. If it persists, remove and re-add the server so it re-runs discovery against https://api.marketordie.io/mcp.

It posts to the wrong workspace

The connection acts as the member you signed in as. Sign out of that Market or Die account in the consent window and reconnect with the right one.
