Get a live stock quote in an AI agent
How do I give an AI agent a current stock price instead of stale training data?
Connect one read-only MCP tool and let the agent retrieve a current quote, compare tickers, or pull price history without maintaining a market-data integration.
The steps
- stock_quote
Retrieve the current quote, change, volume, market state, and key valuation fields for one ticker. - stock_quote_batch
Optional: retrieve up to ten tickers in one call for a watchlist or portfolio view. - stock_compare
Optional: compare price and fundamentals side by side before the agent summarizes them.
Result: A current, source-backed market snapshot your agent can reason over instead of guessing from its training cutoff.
Safe example
stock_quote
{
"symbol": "AAPL"
}Returns the latest available AAPL price, change, volume, day range, market state, market cap, P/E, and 52-week range. Values are fetched live when the authenticated call runs.
This is a fixed documentation example. It makes no API call. The separate anonymous evaluation remains atomically capped at 25 lifetime calls per network; ongoing use requires a metered key.

Save as .vscode/mcp.json. VS Code prompts for the key instead of committing it.

}OpenAI Responses API
Pass LiveDataLink as a remote MCP tool with an authorization header.
const response = await openai.responses.create({
model: "gpt-5.6",
input: "Use LiveDataLink to answer the request.",
tools: [{
type: "mcp",
server_label: "livedatalink",
server_url: "https://livedatalink.ai/mcp",
headers: { Authorization: "Bearer YOUR_API_KEY" },
require_approval: "never"
}]
});Claude and Claude Desktop
Claude's current remote-connector flow accepts authless or OAuth servers and does not accept LiveDataLink's API-key header directly. Do not paste the older claude_desktop_config.json remote-URL example. OAuth support is the remaining prerequisite for a native Claude connector.
