What teams do with NMI through Elaichi

Ask in plain English. Each person’s AI can do only what they’re allowed to, and every action it takes in NMI is logged.

  • Finance

    Look up a payment before answering a query

    Pull up a single NMI transaction by its ID to check the amount, card details and status before replying to a customer or the bank.

  • Support

    Refund or void a charge on the spot

    When a customer calls about a duplicate charge, void it if it has not settled or refund it if it has, without leaving the conversation.

  • Accounts receivable

    Draft, send and close invoices

    Create an invoice in NMI from the details in an email, send it to the customer, then close it once payment arrives.

  • Billing

    Pause or change a customer's subscription

    Find a customer's recurring subscription in NMI and update the amount, schedule or plan when their contract changes, or cancel it when they leave.

  • Operations

    Set up and tidy recurring plans

    Create new pricing plans, list the ones already in NMI, and retire plans nobody is on anymore.

  • Sales

    Authorize a card, capture later

    Run an authorization on a new customer's card to confirm it is good, then capture the payment once the order ships.

Try asking

  • “List all NMI invoices still open past due date.”
  • “Refund the NMI payment on invoice 4821.”
  • “Show yesterday's declined NMI sales by amount.”

Elaichi vs Zapier MCP vs Composio for NMI

All three can connect NMI to an AI assistant, and all three have admin controls. They differ in where access lives and how you pay.

Elaichi compared with Zapier MCP and Composio for NMI, by what to check
What to check Elaichi Zapier MCP Composio
Where the AI connects One address for the whole organization. https://api.elaichi.ai/mcp A server per member, created at sign-in. An MCP endpoint per team, or an SDK.
Control over NMI tools Allow or restrict single NMI tools, per role or user. App and action restrictions on the account. Role permissions, down to the action.
Record of calls One audit entry per NMI call. A History tab of tool calls. A log of every tool call.
Single sign-on SAML or OIDC, plus SCIM, on Gold. SAML on Enterprise. SAML and OIDC on Enterprise.
Price Free for one person; $15 per user per month on Gold. 2 tasks per successful call. Billed per tool call.

Sources: Zapier MCP docs, security, usage; Composio docs, gateway, enterprise, pricing. Checked September 2026.

Longer take: Zapier MCP alternative and when you don't need an MCP gateway.

NMI tools for your AI agents

68 tools are ready to call through Elaichi's MCP endpoint the moment you connect NMI, governed by the same roles, restrictions, and audit log as everything else in Elaichi.

Questions, answered

How do I connect NMI to Claude?

First connect NMI in Elaichi by pasting in an API key from your NMI merchant account, which takes about a minute. Then in Claude go to Customize, then Connectors, then Add, and paste in https://api.elaichi.ai/mcp. There is no OAuth application to register and no client ID or secret to generate, so the NMI side is a single key and nothing else.

Does NMI work with ChatGPT and Cursor as well as Claude?

Yes. Once NMI is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, Microsoft Copilot, any other MCP client and the Elaichi Agent. You connect NMI once and every client your team uses picks it up.

What can an AI agent actually do with my NMI data?

With NMI connected, an agent can look up a payment by its ID, run a sale, authorize and capture a card, void or refund a charge, and create, update, send and close invoices. It can also create and update subscriptions and plans, or list what is already there. Because NMI offers a lot of actions, short concrete asks like "refund transaction 12345" work better than long paragraphs.

Does connecting NMI give the AI access to my whole merchant account?

An agent working through NMI in Elaichi can only do what the API key it was connected with allows, and Elaichi can narrow that further but never widen it. Every call runs under the person who signed in to Elaichi, so a support agent's session cannot do more in NMI than that person is permitted to do.

Can my team share one NMI connection?

Yes. One person connects NMI with the API key, shares the connection with a team in Elaichi, and nobody else ever sees or handles the key. Each teammate still signs in to Elaichi as themselves, so every refund or invoice sent through NMI is logged under the name of the person who asked for it.

Can I stop an agent from refunding, voiding or deleting things in NMI?

Yes. In Elaichi you restrict NMI actions one at a time, so you can allow looking up payments and sending invoices while restricting refunds, voids or deleting subscriptions and plans. A restricted action still appears in Elaichi's tool search, flagged as restricted, but Claude, ChatGPT, Cursor, Microsoft Copilot or any other client cannot run it, whatever the prompt says.

What happens to a NMI connection when someone leaves?

When you offboard someone in Elaichi, their access to NMI through every connected client ends at once. If they had been using a shared NMI connection, it keeps working for everyone else on the team. If you want to remove NMI entirely, disconnecting it once in Elaichi removes it from Claude, ChatGPT, Cursor, Microsoft Copilot and every other client at the same time.

Does the NMI MCP connector work with Gemini, Codex, Claude Code or other MCP clients?

Yes. NMI is reached over the same MCP endpoint every client uses, so anything that speaks MCP can call it — Gemini, Codex, Claude Code, Windsurf, Cline, Zed and OpenCode among them — alongside Claude, ChatGPT, Cursor, Microsoft Copilot, and the Elaichi Agent. The tools on offer and the access behind them are identical whichever client asks. Only the setup screen differs.

Is Elaichi an alternative to Zapier MCP for NMI?

Yes. Both let Claude, ChatGPT or Cursor use NMI. Zapier MCP fits a team that already automates in Zapier, since each person signs in and acts as themselves in that account. Elaichi fits when IT wants one address for the whole company, per-tool rules by role, and a record of every NMI call.

How is Elaichi different from Composio for NMI?

Composio gives AI agents tools and sign-in handling across 1,000+ apps, for developers building agents or people using an assistant, billed per tool call. Elaichi gives a company's own people governed access to NMI: one address, restrictions per role or user, and $15 per user per month. Both have role permissions and a log of every call.
