Save Indian stocks to a watchlist from Claude
add_to_watchlist — Save stocks to your DalalOS watchlist. This is an account-scoped DalalOS watchlist write action. It only saves or removes symbols from the caller's own watchlist; it does not place market orders or modify a brokerage portfolio.
What you can ask
Connect DalalOS to Claude or ChatGPT and ask in plain English; the assistant calls add_to_watchlist for you and answers from the figures it returns.
EXAMPLE PROMPTS
- Add RELIANCE, TCS and INFY to my DalalOS watchlist.
- Add HDFCBANK and ICICIBANK to my watchlist.
- Save the five largest NIFTY IT stocks to my watchlist.

Save stocks to your DalalOS watchlistUSE WHEN
Add one or more symbols to your account-scoped watchlist for later research.
PARAMETERS
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
symbols | list[string] | Yes | — | Non-empty list of NSE symbols, ISINs or BSE codes, capped at 200 items per call. Stored as typed — not resolved against the securities master until get_watchlist reads them back. |
RESPONSE DATA
- Updated watchlist result and added symbols.
NOTES
- Account-scoped write action; it does not store quantity, cost basis or orders.
- Re-adding a symbol already on the watchlist is a no-op, not an error.
- reason_code "unauthorized" if unauthenticated, "not_configured" if the deployment has no watchlist backend wired up.
- Has a REST equivalent: POST /v1/account/watchlist, same credential (API key or OAuth) as this tool.
