Payment Gateway
Plastiq MCP connector
The Plastiq connector lets Claude, ChatGPT, Cursor or any MCP client look up billers, recipients and payments in Plastiq, send payments and refunds, and record every action under the signed-in person's own access.
-
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.

FAQ
Frequently asked questions
How do I connect Plastiq to Claude?
Connect Plastiq in Elaichi first. Plastiq connects with an API key, so you paste the key from your Plastiq account when Elaichi asks for it, and there is no client ID or secret to generate. Then in Claude go to Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp as the endpoint. Claude asks you to sign in to Elaichi, and Plastiq is available from then on.
Does Plastiq work with ChatGPT and Cursor as well as Claude?
Yes. Once Plastiq 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 Plastiq once and every client uses it.
What can an AI agent actually do with my Plastiq data?
An agent connected to Plastiq can search billers, list recipients and payment methods, look up a payment by its ID, and create new payments, payment intents and refunds. It can also add or update recipients and payers, upload documents such as invoices, and browse categories. In practice that means asking who was paid this month, paying a bill by card, or setting up a new vendor, all in plain language.
Does connecting Plastiq give the AI access to every payment and payment method?
No. Every call to Plastiq runs under the API key of the person who connected it, so the agent can only see and do what that Plastiq account can. Elaichi can narrow that further with restrictions per action, and it never widens what the Plastiq account already allows.
Can I stop an agent from creating payments or refunds in Plastiq?
Yes. Restrictions in Elaichi work per action, so you can allow looking up Plastiq billers and payments while blocking the creation of payments, refunds or payment methods. A blocked action is never advertised to Claude, ChatGPT or Cursor at all, so no prompt can reach it.
What happens to a Plastiq connection when someone leaves?
When a person is offboarded in Elaichi, their access to Plastiq through every client ends at once. A Plastiq connection that was shared with a team keeps working for everyone else on that team. If you want Plastiq gone entirely, disconnecting it once in Elaichi removes it from Claude, ChatGPT, Cursor and every other client.
