Describe the whole flow and it is built, tested on every scenario and kept running. SendGrid **4** triggers SendGrid **10** actions Anthropic **9** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want SendGrid and Anthropic 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) SendGrid handles the sending, bounces and suppressions; Anthropic's Claude models read that email activity and write back something a person can act on. Connecting them means a bounce, an unsubscribe or a recipient update in SendGrid can feed a Claude message, and the reply can drive suppression group changes or a notification email sent from SendGrid. Example flows ## What SendGrid can start in Anthropic - When **New bounce** in SendGrid then **Anthropic agent message** in Anthropic - When **New global suppression** in SendGrid then **Send model a message** in Anthropic Starting points drawn from the triggers and actions in the catalog today. Describe the flow you need, at any depth, and your agent builds it and tests every scenario before it ships. Everything your agent can do with SendGrid and Anthropic ## Triggers and actions 4 triggers ยท 19 actions - Trigger **New bounce** Polls the v3 Suppression Bounces API for bounced email addresses.

Yes. The reply from a Claude message on Anthropic can be used as the condition on a SendGrid step, so only the bounces it classifies a certain way are passed to Add to suppression group. The agent tests every scenario, including the case where Claude's answer says to leave the address alone. ### ### Does Anthropic have triggers, so Claude can start a run? No, Anthropic only offers actions here, so every scenario starts from a SendGrid trigger such as a new bounce, a new suppressed email, a new global suppression or a created or updated recipient. Claude steps then run afterwards, and SendGrid actions can follow those. ### ### What can start an automation from SendGrid? Any of SendGrid's 4 triggers in the catalog, including New bounce, New global suppression, New suppressed email and New or updated recipient. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Anthropic when something happens in SendGrid? Any of Anthropic's 9 actions, including Anthropic agent message, Send model a message, Create message batch and Count tokens in a message. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Anthropic to SendGrid? Anthropic has no triggers in the catalog today, so automations start in SendGrid. If you need the other direction, ask: your agent reads Anthropic's API documentation and adds it. ### ### Do I have to build a connector for SendGrid or Anthropic? 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 SendGrid and Anthropic 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.
