Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want AWS Lambda and Calendly 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 Calendly ## Triggers and actions 3 triggers · 20 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 **Canceled scheduled event (polling)** Triggers when a scheduled event is canceled. - Trigger **New scheduled event (polling)** Triggers when a new scheduled event is created. - Action **Cancel scheduled event** Cancels a scheduled event with a specified reason for the cancellation. - Action **Create single-use scheduling link** Creates a single-use booking link that allows one person to schedule an event. - Action **Get current user** Returns the authenticated user's profile including name, email, timezone, and scheduling URL. - Action **Get event type** Returns details for the specified event type. - Action **Get invitee** Returns details about a specific invitee for a scheduled event. - Action **Get invitee next scheduled event** Gets the next scheduled event for the invitee specified by their email. - Action **Get scheduled event** Returns details about a specific scheduled event. - Action **Get user availability schedule** Returns details for the specified user availability schedule. - Action **List event invitees** Returns the list of invitees for a scheduled event, optionally filtered by status. - Action **List event type availability schedules** Returns the event type's availability schedules. - Action **List event types** Returns your calendar's event type templates, optionally filtered by scope and active status. - Action **List organization memberships** Returns all members of the connected Calendly organization (paginated). One record per membership: user_email, user_uri, user_name, role. - Action **List scheduled events** Returns scheduled events, filterable by scope, status, date range, and invitee email. - Action **List user availability schedules** Returns the user's availability schedules. - Action **List webhook subscriptions** Returns all webhook subscriptions for your organization. - Action **Mark invitee as no-show** Records that an invitee did not attend their scheduled event. - Action **Undo invitee no-show** Removes a no-show marking from an invitee. - Action **Update event type availability schedule** Replaces a single host's availability schedule on a Calendly event type with explicit date rules (full overwrite). Built for CalendarConnect: push real Mindbody bookable slots into Calendly so only MBO-bookable times are offered. CRITICAL: the host is targeted by the NESTED availability_rule.user — a top-level user alone is silently ignored and Calendly replaces the OAuth token owner's schedule instead. Always verify stored_user equals the requested host before trusting the result.

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 Calendly when something happens in AWS Lambda? Any of Calendly's 18 actions, including Create single-use scheduling link, Update event type availability schedule, Get current user and Get event type. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Calendly to AWS Lambda? Yes. When something happens in Calendly, your agent can act in AWS Lambda too. This page covers both directions: Calendly's triggers and AWS Lambda's actions are listed here as well. ### ### Do I have to build a connector for AWS Lambda or Calendly? 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 Calendly 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.
