Tools

• timeseries(symbol, interval, exchange?, miccode?, country?, type?, outputsize?, prepost?, dp?, order?, timezone?, date?, startdate?, enddate?, previous_close?, format?, delimiter?) — OHLC time series
• quote(symbol, interval?, exchange?, country?, format?, dp?, prepost?, timezone?, eod?) — quote snapshot
• price(symbol, format?, prepost?) — latest price
• eod(symbol, exchange?, mic_code?, country?, type?, prepost?, dp?, format?) — end-of-day quote
• exchange_rate(symbol, format?, dp?, timezone?) — forex rate (e.g. EUR/USD)
• currency_conversion(symbol, amount, format?, dp?) — FX conversion
• stocks(symbol?, exchange?, mic_code?, country?, type?, format?) — stock symbols
• forexpairs(symbol?, currencybase?, currency_quote?, format?) — forex pairs
• cryptocurrencies(symbol?, exchange?, currencybase?, currencyquote?, format?) — crypto symbols
• etfs(symbol?, exchange?, miccode?, country?, page?, outputsize?) — ETF symbols, paged (default 200 rows; count is the total). A stock ticker returns emptyreason: wronginstrumentclass with a pointer to stocks.
• indices(symbol?, country?, exchange?, miccode?, page?, outputsize?) — index symbols, paged. ~1,300 non-US indices only: US indices (SPX, DJI, IXIC) are not in Twelve Data's reference list, and quoting them requires a Grow-or-higher key via apiKey; a US filter returns that refusal rather than an empty list.
• earnings(symbol, exchange?, country?, miccode?, type?, period?, outputsize?, format?, dp?, startdate?, end_date?) — earnings calendar

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "twelvedata": {
      "url": "https://gateway.pipeworx.io/twelvedata/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/twelvedata/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — askpipeworx, discovertools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1679+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.
