MCP & AI assistants

You can connect your Synci account to AI assistants through the Model Context Protocol (MCP), the open standard that AI clients use to discover and call tools. Synci runs a secure, read-only MCP server, so an assistant can read your financial data when you ask, but it can never move money, change a setting, or delete anything.

What it is

This isn't a transfer link or a destination. Your data does not get pushed anywhere. It's an integration that hands your AI tool a read-only window into your accounts, opened only when you ask and only for what you've allowed.

• Read-only by design. There are no write tools. The server cannot modify, move, or delete anything.

• You choose the accounts. During setup you pick exactly which financial accounts the assistant may read (or grant all, including ones you add later).

• Sensitive details are hidden. Full account numbers, IBANs, card numbers, phone numbers, and account-holder names are never sent to the assistant.

• Sign in once, no keys to copy. Connecting uses a standard Synci sign-in. There are no API keys or tokens to generate and paste.

Requirements

• An active Synci subscription. AI assistants work on every plan, including during a free trial. Without a subscription, the AI Assistants page shows an upgrade prompt.

• An MCP-compatible AI client, such as Claude, ChatGPT, or Perplexity. Any assistant that supports MCP works the same way.

Where to find it

Open AI Assistants from the Integrations section of the sidebar in your Synci Dashboard (if you've unpinned it, you'll find it under All integrations). The page has three parts:

• Connect an assistant: choose your assistant and follow its setup steps.

• Connection details: the MCP server URL, with a copy button.

• Connected assistants: a list of what's connected, with a Disconnect button for each.

How connecting works

Claude and ChatGPT have a shortcut on the AI Assistants page:

• Claude: click Connect to Claude. Claude opens its "Add custom connector" dialog with Synci already filled in. Add the connector, then sign in with Synci.

• ChatGPT: click Connect to ChatGPT to open Synci in the ChatGPT app directory, install it, and sign in with Synci. In a chat, click + and select Synci.

For any other assistant, the flow is generally the same:

1. Copy the Synci MCP server URL:

   Copy code

   https://api.synci.io/mcp

2. In your AI client, add it as a custom connector (also called a remote MCP server).

3. The client opens Synci sign-in.

4. On Synci's authorization page, you'll see the assistant, the permission it's requesting, and an account picker. Choose which accounts it may read.

5. Approve. The assistant now appears under Connected assistants.

There are no secrets or config files to set up for the standard flow.

Synci works with any assistant that supports MCP. The exact menu path differs between clients, and these menus change often, so we keep up-to-date, step-by-step instructions for popular assistants (including Claude, ChatGPT, and Perplexity) in your dashboard under AI Assistants.

Config-file fallback (mcp-remote)

If your client only supports config-file setup rather than remote connectors, you can bridge to the server with mcp-remote. This requires Node.js installed on your machine. Add the block below and restart the client:

{ "mcpServers": { "synci": { "command": "npx", "args": ["-y", "mcp-remote", "https://api.synci.io/mcp"] } } } 

MCP directories

The Synci MCP is available in the following directories:

• ChatGPT app directory

• Official MCP Registry

• Smithery

• Glama

What the assistant can do

Your client discovers Synci's tools automatically, so new tools can appear over time without you changing anything. Today there are five, all read-only:

Data covered: your bank accounts and your investment, brokerage, and crypto-exchange accounts, including their balances, transactions (including trades and other investment activity), and current holdings.

Things you can ask:

• "List my Synci accounts."

• "What's my balance across all accounts?"

• "What did I spend on groceries last month?"

• "How much do I owe on my credit card, and how much credit is left?"

• "What are my crypto holdings worth now, and what's my profit and loss?"

• "List my largest transactions in June."

• "Which of my bank connections are failing?"

Charts and rundowns. Because the assistant reads your real numbers, it can also summarize and visualize them. Most assistants can turn a request into a table, a chart, or a written breakdown:

• "Chart my spending by category for the last three months."

• "Give me a monthly rundown of income vs expenses this year."

• "Show a pie chart of where my money went in June."

• "Compare this month's spending to last month and highlight what changed."

• "Break down my portfolio by asset and show the allocation as a bar chart."

What you get back (a live chart, a downloadable file, a plain table) depends on the assistant you're using, not on Synci. Synci supplies the data; the assistant decides how to present it.

Security and privacy

• Strictly read-only. The server exposes read tools only. It cannot reach the rest of the Synci API or any other part of your account.

• Scoped to the accounts you pick. Everything you don't select stays invisible to the assistant.

• Sensitive identifiers are stripped before any data leaves Synci: IBANs and account numbers, card numbers, phone numbers, and account-holder names.

• Consent is explicit and revocable. You approve on Synci's own authorization page and can disconnect instantly.

• Only connect assistants you trust. Synci doesn't verify AI assistants. When you connect one Synci doesn't recognize, the authorization page says so and shows where access will be delivered, so you can check that it matches the app you're connecting.

Synci is independent and not affiliated with Anthropic, OpenAI, Perplexity, or any other assistant. Their names are used only to describe compatibility.

Good to know

A few honest caveats so answers stay accurate rather than confidently wrong:

• Balances can lag transactions. Balances sync on their own schedule, and some banks limit how often they can be fetched, so a balance may be older than the transactions around it. Every balance carries a "last synced" date, and the assistant is told to flag a stale balance rather than present it as current.

• Enrichment gives cleaner answers. With transaction enrichment enabled (Pro), the assistant sees tidy merchant names and categories. Without it, it works from raw bank text, which can be terse. Enrichment is a good idea if you want better AI answers.

Managing and disconnecting

The Connected assistants list on the AI Assistants page shows each assistant's name, developer, the permission it holds, which accounts it can read, and when it connected. Disconnect cuts off access immediately; reconnecting requires approving again. For more on consent, per-account control, and notifications, see Managing third-party apps and AI assistants.
