Setup
How do you connect Barclays Corporate to AI assistants?
Synci syncs new transactions and balances automatically, including pending transactions where the bank exposes them, and your first sync imports up to 730 days of history.
Connect securely
Log in through Barclays Corporate's own PSD2 flow. Synci never sees or stores your credentials.
Pick accounts
Choose which Barclays Corporate accounts your assistant is allowed to read. Everything else stays invisible to it.
Add the MCP server
Add Synci's MCP server URL as a connector in Claude, ChatGPT, Perplexity, or Grok, then sign in. Setup differs per client, so each has its own page with exact steps.
Ask anything
Your assistant reads the latest synced balances and transactions from the Barclays Corporate accounts you picked, and answers in plain language.

Scope
Exactly what an assistant can and cannot do with Barclays Corporate.
Assistants reach your Barclays Corporate accounts through five read-only tools, and nothing else.
- list_accounts
- get_account_balance
- list_transactions
- list_holdings
- list_connections
AI assistants can
- List the accounts you shared, across banks, brokerages and crypto exchanges
- Read recent balance snapshots, with the timestamp they were taken
- Read transactions in a date range you or it asks for
- Read investment and crypto holdings: symbol, quantity, market value
- Check the health of your connections, so it can tell you when data is stale
AI assistants cannot
- Move money, make payments, or place trades
- Change anything at all: the server is read-only and has no write operations
- See accounts you did not share, or reach your bank directly
- See your bank login, which never leaves your bank's own flow
- See sensitive identifiers: IBAN, BBAN, card numbers, phone numbers and owner names are omitted
Enrichment is opt-in and separate from this: when you turn it on, only pseudonymised transaction data reaches our enrichment provider, and it is never used to train models or shared with unrelated third parties. See our privacy policy for the detail.

FAQ
Common questions
Yes, once you connect Barclays Corporate to Synci and choose which accounts to share. You add Synci's MCP server as a connector in your assistant, and it can then read balances, transactions and holdings from those accounts. The assistant never reaches Barclays Corporate itself; it only ever sees what Synci has already synced.
It can list the accounts you shared, read balance snapshots, read transactions in a date range, and check whether a connection has gone stale. It cannot move money, place trades, or change anything: the server is read-only. It also cannot see accounts you did not share, and sensitive identifiers like IBAN and card numbers are stripped before anything reaches it.
Your first sync imports up to 730 days of Barclays Corporate history, and Synci keeps everything that arrives after that. Assistants see 60 days on Basic and up to 2 years on Pro, where Barclays Corporate provided it.
Assistants read your latest synced data on demand rather than being sent updates. Synci polls Barclays Corporate every hour to every 6 hours depending on your plan, so answers reflect recent activity rather than the moment you last opened an app.
Yes. Barclays Corporate exposes pending transactions through PSD2, so an assistant can see them alongside booked ones. When Barclays Corporate books a pending transaction, Synci updates the existing record rather than creating a duplicate, so nothing is counted twice.
Barclays Corporate may not expose credit card accounts through PSD2. If yours does, they appear in the list when you connect and you can choose whether to share them.
ChatGPT, Claude, Perplexity, Grok, and any other MCP-compatible client. You add Synci's MCP server URL as a connector and sign in, with no API keys to manage. Each assistant has its own page here with step-by-step setup for that client.
Yes, at any time. You choose which Barclays Corporate accounts each assistant can see, you can change that selection later, and you can disconnect an assistant from Synci entirely without touching the bank connection itself.
No. Synci connects to Barclays Corporate through regulated PSD2 APIs, which means authentication happens in Barclays Corporate's own login flow. Your credentials are never shared with Synci, and never with your assistant.
Synci currently connects to Barclays Corporate through GoCardless, a regulated PSD2 data provider. Providers handle the technical connection to the bank; your login credentials stay between you and Barclays Corporate, and your assistant sees neither.
By assistant
Pick the assistant you actually use.
The Barclays Corporate connection is the same in every one of them. Only the setup differs, and each has its own page with exact steps.
Bank data in ChatGPT
Synci is published in ChatGPT's directory, so setup takes a minute: search for Synci, click Install, then sign in. ChatGPT can then pull your real balances, transactions, and holdings into a conversation.
Bank data in Claude
Add Synci's MCP server URL as a custom connector in Claude and sign in with your Synci account. Claude can then read the accounts you allow and work through up to two years of transactions, where your bank provides it: year-over-year comparisons, net worth across institutions, or where a category quietly grew.
Bank data in Perplexity
Perplexity supports MCP connectors too: add Synci's MCP server, sign in, and ask about your balances, transactions, and holdings alongside Perplexity's web research, all read-only and limited to the accounts you pick.
Bank data in Grok
Go to grok.com/connectors, choose New Connector and then Custom, and enter Synci's MCP server URL. After you sign in, Grok can read the accounts you shared. On Grok Business and Enterprise a team admin provisions the connector first.
