Describe the whole flow and it is built, tested on every scenario and kept running. FreeAgent **6** triggers FreeAgent **50** actions Mailjet **3** triggers Mailjet **16** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want FreeAgent and Mailjet to do together? Give your AI client this address. `https://mcp.apiant.ai` One 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. ### Set it up in your client ### Claude Code Run this in the directory you want to work in. `claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai` Start Claude Code there, approve the server, and sign in in the browser page it opens. [Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code) ### Claude, web and desktop Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Cursor Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Zed Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Codex and the ChatGPT desktop app 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)](https://apiant.ai/docs/mcp) ### 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)](https://apiant.ai/docs/mcp) Running Mailjet alongside FreeAgent usually means typing the same client details twice. Connecting them lets a new FreeAgent contact or invoice create or update the matching Mailjet contact, put them on the right list, and send the email that goes with it — and lets Mailjet list sign-ups land in FreeAgent as contacts ready to invoice.

No — the agent can use Get Contact in Mailjet to check for the email address first, and only run Create Contact when nothing comes back. If the contact is already there, it can add them to a list or update their details instead. ### ### Can the invoice details be included in the email Mailjet sends? Yes. The FreeAgent New Invoice trigger carries the invoice fields, and Mailjet's Send Email action can use them in the subject and body. If more detail is needed, Get Invoice can pull the full record before the email goes out. ### ### What can start an automation from FreeAgent? Any of FreeAgent's 6 triggers in the catalog, including New Contact, New Invoice, New Project and New Bank Transaction. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Mailjet when something happens in FreeAgent? Any of Mailjet's 16 actions, including Add Contact to List, Get Contact, Send Email and Create Contact. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Mailjet to FreeAgent? Yes. When something happens in Mailjet, your agent can act in FreeAgent too. This page covers both directions: Mailjet's triggers and FreeAgent's actions are listed here as well. ### ### Do I have to build a connector for FreeAgent or Mailjet? 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 Mailjet 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.
