Alpaca MCP connector

The Alpaca connector brings live and historical stock and crypto market data, news, and top movers into Claude, ChatGPT, Cursor, and the Elaichi Agent, so anyone on your team can ask about prices in plain language.

  • How it connects. Connects with an API key. The credential goes into a vault nobody reads back.

  • One address. https://api.elaichi.ai/mcp, the same for every user.

  • Their own access. An agent never gets more than the person it acts for.

How to connect

FAQ

Frequently asked questions

How do I connect Alpaca to Claude?

Connect Alpaca in Elaichi first by pasting your Alpaca API key when prompted. There is no OAuth application to register and no client ID or secret to generate. Then in Claude go to Customize, then Connectors, then Add, and paste the endpoint https://api.elaichi.ai/mcp. Sign in to Elaichi as yourself and Alpaca market data is available in Claude.

Does Alpaca work with ChatGPT and Cursor as well as Claude?

Yes. Once Alpaca is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, any other MCP client, and the Elaichi Agent. You connect Alpaca once and every client picks it up.

What can an AI agent actually do with my Alpaca data?

With Alpaca connected, an agent can look up the latest quote, trade, and snapshot for a stock or crypto pair, pull historical bars over any date range, show the spread between bid and ask, list today's top movers, and read recent market news. Because Alpaca has a large set of actions, short concrete asks such as "latest quote for AAPL" work better than long sentences. The agent finds the right action and returns the numbers in the conversation.

Does connecting Alpaca give the AI access to everything in my account?

No. The agent can only reach what the Alpaca API key you connected can reach, and this connector covers market data such as bars, quotes, trades, snapshots, news, and movers. Elaichi can narrow that further with restrictions, but it can never widen it beyond what the connected Alpaca key allows.

Can my team share one Alpaca connection?

Yes. One person connects Alpaca with their API key and shares the connection with a team in Elaichi. Nobody else ever sees or handles the key, and each teammate still signs in to Elaichi as themselves, so the audit log names the person who asked for each Alpaca quote or bar.

Can I stop an agent from deleting or changing things in Alpaca?

The Alpaca connector in Elaichi reads market data, so its actions look up bars, quotes, trades, snapshots, news, and movers rather than placing orders or editing anything. Restrictions still apply per action, so you can switch off any Alpaca action you do not want used. A blocked action is never advertised to Claude, ChatGPT, or Cursor, so no prompt can reach it.

What happens to an Alpaca connection when someone leaves?

Offboarding a person in Elaichi ends their access to Alpaca at once, in every client they used. If the Alpaca connection was shared with a team, it keeps working for everyone else. Disconnecting Alpaca once in Elaichi removes it from Claude, ChatGPT, Cursor, and every other client at the same time.
