How it works

Plug in, ask questions

OAuth sign-in works with any supporting client — no key needed. Claude (Desktop, Code, and claude.ai), ChatGPT, and Perplexity all work today; Cursor, Windsurf, and others will work the same way as they add OAuth-based MCP support. Not working with your client? Tell us — or fall back to a free API key below. Full setup guide →

# Claude (Desktop, Code, or claude.ai) — no key needed, OAuth handles it
Settings → Connectors → search for Stocklake, or use
URL: https://api.stocklake.dev/mcp
→ connect → sign in with magic link → done

# Python (fastmcp) — or any non-OAuth client, using a free API key
from fastmcp import Client
from fastmcp.client.transports import StreamableHttpTransport

transport = StreamableHttpTransport(
    url="https://api.stocklake.dev/mcp",
    headers={"Authorization": "Bearer sl_your_key_here"},
)

async with Client(transport) as mcp:
    result = await mcp.call_tool("get_stock", {"symbol": "NVDA"})  # pro key → adds .rating + .signals
