# Invoiced MCP connector The Invoiced connector brings customers, invoices, payments and balances into Claude, ChatGPT and Cursor, so once connected, each person can create, send and check invoices inside their own Invoiced access with every action logged. Source: https://elaichi.ai/connectors/invoiced/ ## Facts | | | | --- | --- | | Application | Invoiced | | Category | Accounting | | AI tools | 110 | | Authentication | Connects with an API key | | Needs your own OAuth app | No | | MCP endpoint | https://api.elaichi.ai/mcp | | Works with | Claude, ChatGPT, Cursor, any MCP client, and the Elaichi Agent | | Tools advertised by name | No. 110 tools is past the 30-tool threshold, so clients use `search_tools` and `execute_tool` | ## What you can ask once Invoiced is connected - Which customers are overdue on their latest invoice balance. - Draft a statement email for our top five customers. - Summarize invoices created this week by team. ## Connect Invoiced in Elaichi This happens once for the organization, before any client is involved. 1. Open Connections, choose Add connection, and pick Invoiced. 2. Optionally set Share with, then press Connect. 3. Paste an Invoiced API key. One person generates a token in Invoiced and pastes it once. Everyone else works through Share with, and never sees it. Credentials are vaulted and nobody, including the AI, reads them back. The connection becomes a toolbox immediately, so you can curate which Invoiced tools are exposed, rename them, or freeze arguments before anyone points a client at it. ## Connect Invoiced to Claude Endpoint: https://api.elaichi.ai/mcp 1. Open Customize, then Connectors. 2. Press Add. 3. Name it, paste the MCP server URL, then Continue. 4. Sign in and approve. On Team and Enterprise, an Owner adds it once. Everyone else turns it on for themselves. ## Connect Invoiced to ChatGPT Endpoint: https://api.elaichi.ai/mcp 1. Open Plugins, then press the + button. 2. Name it and paste the endpoint into Server URL. 3. Leave Authentication on OAuth, then tick the risk acknowledgement. 4. Press Create, then sign in and approve. Works on the web today. The plugin directory lives at chatgpt.com/plugins. ## Connect Invoiced to Cursor Endpoint: https://api.elaichi.ai/mcp 1. Open `~/.cursor/mcp.json`. 2. Add the endpoint under `mcpServers`. 3. Reload Cursor, then sign in and approve. Set up per machine, so repeat it on each computer you work from. ## Connect Invoiced to any MCP client Endpoint: https://api.elaichi.ai/mcp 1. Add the endpoint as a remote MCP server. 2. Sign in and approve. The Elaichi Agent already has these tools, with nothing to set up. ## What the consent screen decides Only Read is granted by default, which is not enough to call a Invoiced tool. Over MCP there is no trusted place to confirm a write in the moment, so the consent screen is the standing approval rather than a formality. Grant Read and Run tools. Think hard before granting Delete, which reaches into connected apps and cannot be undone. ## What teams do with Invoiced through Elaichi ### Send a statement to a late payer Accounts receivable. Ask for a customer's outstanding balance in Invoiced, then send them a statement by email, text message or letter without leaving the conversation. ### Record a payment that arrived by wire Finance. Log the payment against the right Invoiced invoice the moment the bank shows it, then confirm the customer's balance has dropped to zero. ### Raise the invoice right after closing Sales. Create the customer in Invoiced if they are new, draft the invoice with the agreed line items, and email it before the follow-up call is over. ### Consolidate open invoices into one Customer success. Roll a customer's scattered Invoiced invoices into a single consolidated invoice so they pay once instead of juggling five separate documents. ### Answer 'what do I owe you' quickly Support. Pull up a customer's balance and open invoices in Invoiced while they are on the phone, and resend the invoice by email or text on the spot. ### Void a duplicate invoice before it ships Operations. Find the duplicate in Invoiced, void it, and correct the customer record so the mistake never reaches the mailbox. ## Frequently asked questions ### How do I connect Invoiced to Claude? Connect Invoiced in Elaichi by pasting in an API key from your Invoiced settings. There is no OAuth application to register and no client ID or secret to generate. Then in Claude open Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp. Sign in to Elaichi when Claude asks and your Invoiced customers, invoices and payments are ready to work with. ### Does Invoiced work with ChatGPT and Cursor as well as Claude? Yes. Once Invoiced 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 Invoiced once and every client picks it up. ### What can an AI agent actually do with my Invoiced data? It can look up a customer in Invoiced and tell you their balance, create or update customers and invoices, send an invoice or statement by email, text message or letter, record a payment, consolidate several invoices into one, and void an invoice raised by mistake. Invoiced offers a lot of actions, so short concrete asks such as 'send Acme their statement by email' work better than long paragraphs. ### Does connecting Invoiced give the AI access to my whole billing account? No. Every call to Invoiced runs as the person who signed in, so the agent can only see and change the customers, invoices and payments that person could already reach in Invoiced. Elaichi can narrow that further, for example to reading balances only, but it never widens what someone is allowed to do. ### Can my team share one Invoiced connection? Yes. One person connects Invoiced with an API key and shares the connection with a team in Elaichi, and nobody else ever handles the key. Each teammate still signs in to Elaichi as themselves, so the audit log names the actual person who sent an invoice or recorded a payment in Invoiced. ### Can I stop an agent from deleting or voiding things in Invoiced? Yes. Restrictions in Elaichi work per action, so you can allow creating and sending invoices in Invoiced while blocking deleting customers, voiding invoices or changing payments. A blocked action is never shown to Claude, ChatGPT or Cursor at all, so no prompt, however worded, can reach it. ### What happens to an Invoiced connection when someone leaves? Offboarding that person in Elaichi ends their access to Invoiced through every client at once. A shared Invoiced connection keeps working for everyone else on the team. If you ever want Invoiced gone entirely, disconnecting it once in Elaichi removes it from Claude, ChatGPT, Cursor and every other client together. ## All 110 Invoiced tools Every tool below is callable through https://api.elaichi.ai/mcp once Invoiced is connected, subject to the toolbox it is in and the restrictions on the caller. - **Create a Invoiced customer** (Create).
