Build an MCP server for live stock data

Tired of pasting numbers, a builder made an MCP server for ~8,200 NSE and BSE stocks so Claude stops inventing P/Es.

Prompt for your agent

Goal: Give my agent real market data instead of copy-paste.
Setup: agents used in source: Claude; tools/MCPs stated: MCP.
Steps:
1. Build an MCP server over the exchange data you need (here all NSE + BSE stocks).
2. Connect it to Claude so it pulls numbers instead of recalling them.
Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
