MCP server for Tapefund — the public Robinhood Agentic swing-trading book, trading journal, holdings, and all-in rules. For Cursor, Claude Desktop, and other MCP clients.

Install from npm: npx -y tapefund-mcp (current 0.1.0).

MCP Registry name: io.github.Jcjimenezglez/tapefund-mcp.

This is not a brokerage. Tools are read-only. They do not place orders and they do not expose Robinhood credentials.

Install

Add to .cursor/mcp.json (Cursor) or Claude Desktop config:

{
  "mcpServers": {
    "tapefund": {
      "command": "npx",
      "args": ["-y", "tapefund-mcp"],
      "env": {
        "TAPEFUND_API_URL": "https://tapefund.com"
      }
    }
  }
}

No API key is required for the public ledger. Optional TAPEFUND_API_KEY is accepted (X-API-Key / Authorization: Bearer) for when billing ships.

Environment variables

Variable	Required	Default	Description
`TAPEFUND_API_URL`	No	`https://tapefund.com`	Tapefund origin (REST JSON under `/api/v1/`)
`TAPEFUND_API_KEY`	No	—	Optional prepaid key (not enforced on public JSON yet)

Tools

Tool	REST	Description
`get_book_snapshot`	`GET /api/v1/snapshot.json`	NAV, return vs $100, cash/open
`get_closed_trades`	`GET /api/v1/closed-trades.json`	Closed ledger rows
`get_holdings`	`GET /api/v1/holdings.json`	Open names
`get_latest_thinking`	`GET /api/v1/thinking.json`	Latest CIO markdown
`get_all_in_rules`	`GET /api/v1/rules.json`	All-in hard rules
`get_journal_day`	`GET /api/v1/journal/{date}.json`	Sessions for a date
`get_credit_usage`	`GET /api/v1/credit-usage.json`	Access / credit status

Same pattern as rosetta-mcp: stdio MCP client over HTTPS REST. Tapefund’s site is a static export, so REST is public JSON (no /api/mcp Streamable HTTP on tapefund.com yet).
