Connect Claude to your crypto portfolio with the MCP server
Give Claude read-only access to your whole portfolio on Kraken, Coinbase, OKX, Hyperliquid and IBKR: positions, orders, fills and transfers, through the MCP server.
CentraFIN's MCP server gives Claude, and any assistant that supports the Model Context Protocol, read-only access to your combined portfolio: your Kraken, Coinbase, OKX, Hyperliquid and Interactive Brokers accounts as one source. You ask your question; Claude reads your current figures before it answers.
What Claude can read
| Tool | What it returns |
|---|---|
| Portfolio | Your total value in euros, your unrealised gain, the value of each market |
| Positions | Each asset: quantity, price, value, average entry price, gain |
| Open orders | Your open orders on each account: limits, stops, take profits |
| Filled orders | Your fills: side, quantity, price, fees |
| Transfers | Your deposits and withdrawals, account by account |
| Connectors | Your connected accounts and the state of their last read |
Claude never sees your private wallets: they stay encrypted in your browser.
Connect it to Claude
- In Claude, open Settings › Connectors, then Add custom connector.
- Give it a name (“CentraFIN”, for example) and the address https://app.centrafin.xyz/mcp.
- Sign in to CentraFIN when Claude asks you to, then allow read access.

What you can ask it
- “What share of my portfolio is in perpetuals?”
- “Which open orders are furthest from the current price?”
- “Sum up my fills this week on Kraken and Hyperliquid.”
- “How much have I deposited on Coinbase this year?”
Your security
- Read-only: every tool only reads; none can place an order or move funds.
- Access you allow: OAuth 2.1 with PKCE; an access token lasts one hour, a refresh token 30 days.
- Revocable: in the connected apps section of CentraFIN's settings, one click removes the access.
- Without your private wallets: the server cannot read them, as it does not hold their key.
Which plan includes it
The MCP server is included in the CentraFIN Professional plan. The accounts it reads connect as usual: Kraken, Coinbase, OKX, Hyperliquid and Interactive Brokers.
Frequently asked questions
Can Claude place orders for me?
No. The server offers only reading tools, and your platforms' keys are read-only themselves.
How do I remove the access?
In the connected apps section of CentraFIN's settings, revoke the app: its tokens stop working at once.
Does it work with assistants other than Claude?
Yes, with any client that accepts a remote MCP server (Streamable HTTP) and OAuth: the same address is all it needs.
Who gets my figures?
Only the assistant you allow, at the moment it asks for them. What it then does with them is governed by its own terms, which you can check with its provider.
