Integration
Connect FreeAgent and Stripe
When New Contact fires in FreeAgent, your agent runs Create Customer in Stripe, or New Customer in Stripe to Create Invoice in FreeAgent. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.
Setup guide (opens in a new tab)Any other MCP client
Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.
Setup guide (opens in a new tab)Stripe handles the money coming in and FreeAgent keeps the books, so the same customer usually gets typed twice. Connecting them means a Stripe customer, charge or subscription can create the matching FreeAgent contact, invoice or project, and a FreeAgent contact or invoice can open the matching customer or payment intent in Stripe.

Questions
FreeAgent and Stripe, answered
Will it create a duplicate FreeAgent contact for a customer we already bill?
No, the agent can list FreeAgent contacts first and only create one when no contact matches the email on the Stripe customer. When a match is found it uses that contact and can update it instead.
Can a FreeAgent invoice be paid through Stripe?
The agent can create a Stripe payment intent for the invoice total when a new invoice appears in FreeAgent. Collecting the payment itself still happens in Stripe's checkout flow, and the resulting charge can then be read back.
What can start an automation from FreeAgent?
Any of FreeAgent's 6 triggers in the catalog, including New Contact, New Invoice, New Bank Transaction and New or Updated Contact. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Stripe when something happens in FreeAgent?
Any of Stripe's 21 actions, including Create Customer, Create Payment Intent, Create Charge and Create charges (bulk charge creation). Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Stripe to FreeAgent?
Yes. When something happens in Stripe, your agent can act in FreeAgent too. This page covers both directions: Stripe's triggers and FreeAgent's actions are listed here as well.
Do I have to build a connector for FreeAgent or Stripe?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use FreeAgent and Stripe without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
