Describe the whole flow and it is built, tested on every scenario and kept running. Amazon SNS **3** triggers Amazon SNS **3** actions AWS Lambda **1** trigger AWS Lambda **2** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want Amazon SNS and AWS Lambda 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.

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 Amazon SNS and AWS Lambda ## Triggers and actions 4 triggers · 5 actions - Trigger **New JSON Message** Triggers instantly when a message is published to an Amazon SNS topic and passes on the JSON data in the message. The subscription is created and removed automatically when the automation is turned on and off. - Trigger **New Message** Triggers instantly when a message is published to an Amazon SNS topic. The subscription is created and removed automatically when the automation is turned on and off. - Trigger **New Topic** Triggers when a new topic is created in the connected Amazon SNS account. - Action **Create JSON Message** Publishes a message to an Amazon SNS topic whose body is JSON built from the data you map, such as a record from the trigger. - Action **Create Message** Publishes a text message to an Amazon SNS topic, delivering it to every subscriber. - Action **Create Topic** Creates a new Amazon SNS topic, or returns the existing one if a topic with that name already exists. - Trigger **New Function** Triggers when a new AWS Lambda function is created in the connected region. - Action **Invoke Function (Async)** Starts an AWS Lambda function with the data you provide and continues without waiting for it to finish. - Action **Invoke Function (Sync)** Runs an AWS Lambda function with the data you provide, waits for it to finish, and returns what it returned. ## Each app on its own - [ **Amazon SNS** Amazon Simple Notification Service is a flexible, and fast messaging service which is fully managed.](https://apiant.ai/connections/amazon-sns) - [ **AWS Lambda** AWS Lambda is a compute service that runs your code in response to events and automatically manages the...](https://apiant.ai/connections/aws-lambda) Reviews ## What our customers say ## More from Amazon SNS - [ **Amazon SNS to HubSpot** HubSpot is your all-in-one stop for all of your marketing software needs.](https://apiant.ai/connect/amazon-sns-to-hubspot) - [ **Amazon SNS to Salesforce** Salesforce is a leading enterprise customer relationship management (CRM) platform.](https://apiant.ai/connect/amazon-sns-to-salesforce) - [ **Amazon SNS to Slack** Slack is a messaging platform for teams.

Any of Amazon SNS's 3 triggers in the catalog, including New JSON Message, New Message and New Topic. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in AWS Lambda when something happens in Amazon SNS? Any of AWS Lambda's 2 actions, including Invoke Function (Async) and Invoke Function (Sync). Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from AWS Lambda to Amazon SNS? Yes. When something happens in AWS Lambda, your agent can act in Amazon SNS too. This page covers both directions: AWS Lambda's triggers and Amazon SNS's actions are listed here as well. ### ### Do I have to build a connector for Amazon SNS or AWS Lambda? 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 Amazon SNS and AWS Lambda 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.
