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.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) Slack is where lead and call details get dropped in as plain messages, and Trestle can tell you whether the phone, name and address behind them are real. Connecting the two means a number posted in a channel can be checked, graded and named without anyone leaving the conversation, with the answer posted back where the team is already reading.

Every scenario starts in Slack: a message posted to a channel, a thread reply, a reaction, a pin or a mention. Trestle is always the side doing the work, such as Identify caller, Phone Validation or Real Contact, and the result can come back as a Slack message. ### ### Can the result be posted back into the same conversation? Yes. After a Trestle lookup the agent can use Send Message to post the findings to the channel or thread, and actions like Pin Message to keep an important lead visible. The agent tests every scenario before it goes live. ### ### What can start an automation from Slack? Any of Slack's 15 triggers in the catalog, including New Mention (instant), New Message Posted to Channel, New Pinned Item and New Reaction Added. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Trestle when something happens in Slack? Any of Trestle's 7 actions, including Identify caller, Phone Validation, Real Contact and Reverse Address. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Trestle to Slack? Trestle has no triggers in the catalog today, so automations start in Slack. If you need the other direction, ask: your agent reads Trestle's API documentation and adds it. ### ### Do I have to build a connector for Slack or Trestle? 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 Slack and Trestle 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.
