Add SN Data to Claude Code
Make a free Shikshan Nivesh account and copy your key from your account page, under Data. It starts with sn_live_. Put it in an environment variable, so the add command carries $SN_KEY in place of the key itself, then add SN Data with one line.
Claude Code replies "Added HTTP MCP server sn-data" and shows the key as [REDACTED]. By default the server is added to the local scope: private to you, and only in the folder you ran the command from. Add --scope user to have SN Data in every folder you open Claude Code in.
export SN_KEY=sn_live_your_key claude mcp add --transport http sn-data \ https://shikshannivesh.com/mcp \ --header "Authorization: Bearer $SN_KEY" # or, for every folder claude mcp add --scope user \ --transport http sn-data \ https://shikshannivesh.com/mcp \ --header "Authorization: Bearer $SN_KEY"

Check that it connected
claude mcp list checks each server and says whether it connected. claude mcp get sn-data shows the scope, the address and the status. Inside a Claude Code session, /mcp shows the same list.
If the key is wrong or was deleted, the check reads "Failed to connect" with HTTP 401, and SN Data's message says the sign-in has expired or was made with a deleted key. Copy the key again from your account page, remove the server with claude mcp remove sn-data and add it again.
Ask about a company
Start claude in any folder and ask in plain words. The first time Claude Code wants one of SN Data's tools, it asks before using it; say yes and it reads the record. Naming SN Data in the question tells Claude Code where to look.
For a one-off answer printed straight to the terminal, claude -p runs a single question and exits, which is how the answer above was made. A run like that cannot stop to ask, so allow SN Data's tools up front with --allowedTools.
claude -p "Compare Apple's revenue over its \ last three fiscal years with NVIDIA's, using \ SN Data, and cite the 10-Ks. Keep it short." \ --allowedTools "mcp__sn-data__*"
Questions to try
Claude Code works in a folder of files, so an answer can become a file you keep: a table saved as CSV, notes on a company in Markdown, the same comparison rerun next quarter. A few questions to start with:
For a longer walk through one research setup built on Claude Code, with its notes kept in Obsidian, see the post below.
Using SN Data, pull Microsoft's revenue and operating income for the last 8 quarters and save them to msft-quarters.csv. From SN Data, list NVIDIA's insider sales in the last 12 months and mark which were under a 10b5-1 trading plan, with each Form 4 link. Which funds held the most Costco shares in the latest 13F filings, according to SN Data? Show the top 10 and what each added or trimmed.

What the free key covers
A free key answers 250 calls a day, at most 60 a minute, on the last 5 fiscal years of every covered company. A question like the Apple and NVIDIA one uses a few calls. When a question reaches for a year outside the plan, SN Data says which years the plan covers and gives no figure for the others.
The Individual plan, $19 a month, opens every year back to fiscal 2007 at up to 300 calls a minute. The same key works in the API, Excel, Google Sheets and other AI assistants, all from one daily limit.
So with one command Claude Code can read any US company's filings, and its answers come back with the 10-K, 10-Q or Form 4 behind each figure.
