Describe the whole flow and it is built, tested on every scenario and kept running. PostStack **7** triggers PostStack **31** actions Parallel Web Systems **13** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want PostStack and Parallel Web Systems 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.

Any of PostStack's 7 triggers in the catalog, including Contact Updated (instant), New Contact (instant), New Inbound Email and New Sent Email (instant). Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Parallel Web Systems when something happens in PostStack? Any of Parallel Web Systems's 13 actions, including Create Async Web Enrichment, Update monitor, Add FindAll run and Add monitor. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Parallel Web Systems to PostStack? Parallel Web Systems has no triggers in the catalog today, so automations start in PostStack. If you need the other direction, ask: your agent reads Parallel Web Systems's API documentation and adds it. ### ### Do I have to build a connector for PostStack or Parallel Web Systems? 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 PostStack and Parallel Web Systems 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.
