get_last_quote

Instructions

Implementation Reference

• src/massive_mcp/tools/quotes.py:12-18 (handler)

  The actual handler function for the get_last_quote tool. It calls the Massive REST API at /v2/last/nbbo/{ticker} to get the most recent NBBO quote for a stock.

  async def get_last_quote(ticker: str) -> dict[str, Any]:
      """Most recent NBBO (bid/ask) quote for a stock.
  
      Args:
          ticker: Stock symbol (e.g. "AAPL").
      """
      return await client.get(f"/v2/last/nbbo/{ticker}")

• src/massive_mcp/tools/quotes.py:11-18 (registration)

  The tool is registered via the @mcp.tool() decorator inside the register() function in quotes.py.

  @mcp.tool()
  async def get_last_quote(ticker: str) -> dict[str, Any]:
      """Most recent NBBO (bid/ask) quote for a stock.
  
      Args:
          ticker: Stock symbol (e.g. "AAPL").
      """
      return await client.get(f"/v2/last/nbbo/{ticker}")

• src/massive_mcp/server.py:37-48 (registration)

  The quotes module (containing get_last_quote) is registered via module.register(mcp, client) in server.py's build_server() function.

  for module in (
      aggregates,
      quotes,
      snapshots,
      tickers,
      news,
      reference,
      indicators,
      corporate,
      financials,
  ):
      module.register(mcp, client)

• src/massive_mcp/client.py:47-89 (helper)

  MassiveClient.get() is the helper/utility that performs the actual HTTP GET request. get_last_quote calls this with the path /v2/last/nbbo/{ticker}.

  async def get(
      self, path: str, params: dict[str, Any] | None = None, *, trim: bool = True
  ) -> dict[str, Any]:

              )
