Describe the whole flow and it is built, tested on every scenario and kept running. AWS Lambda **1** trigger AWS Lambda **2** actions Rossum **1** trigger Rossum **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 AWS Lambda and Rossum 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 AWS Lambda and Rossum ## Triggers and actions 2 triggers · 11 actions - 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. - Trigger **Document Export** Triggers when a document is exported in Rossum. - Action **Add queue** Create a queue. - Action **Confirm annotation** Confirm an annotation. - Action **Delete annotation** Delete an annotation. - Action **Get annotation** Retrieve one annotation (extracted document data) by id. - Action **Get document** Retrieve document metadata by id. - Action **Get queue** Retrieve a queue by id. - Action **Start Annotation** moves an annotation (e.g. to_review) into reviewing status so it can be confirmed; returns the annotation and session timeout. - Action **Update annotation** Update an annotation (e.g. metadata, status). - Action **Upload a Document** Uploads a document to one of Rossum queues ## Each app on its own - [ **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) - [ **Rossum** Rossum is cloud-based app that uses artificial intelligence to replicate the human approach to data...](https://apiant.ai/connections/rossum) Reviews ## What our customers say ## More from AWS Lambda - [ **AWS Lambda to HubSpot** HubSpot is your all-in-one stop for all of your marketing software needs.](https://apiant.ai/connect/aws-lambda-to-hubspot) - [ **AWS Lambda to Salesforce** Salesforce is a leading enterprise customer relationship management (CRM) platform.](https://apiant.ai/connect/aws-lambda-to-salesforce) - [ **AWS Lambda to Slack** Slack is a messaging platform for teams.

Any of AWS Lambda's 1 trigger in the catalog, including New Function. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Rossum when something happens in AWS Lambda? Any of Rossum's 9 actions, including Update annotation, Upload a Document, Add queue and Confirm annotation. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Rossum to AWS Lambda? Yes. When something happens in Rossum, your agent can act in AWS Lambda too. This page covers both directions: Rossum's triggers and AWS Lambda's actions are listed here as well. ### ### Do I have to build a connector for AWS Lambda or Rossum? 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 AWS Lambda and Rossum 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.
