Integration
Connect Langfuse and Trail
When New Trace fires in Langfuse, your agent runs Create Task in Trail, or Task Completed in Trail to Add Comment in Langfuse. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.
What do you want Langfuse and Trail to do together?

Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne 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.

Questions
Langfuse and Trail, answered
What can start an automation from Langfuse?
Any of Langfuse's 1 trigger in the catalog, including New Trace. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Trail when something happens in Langfuse?
Any of Trail's 11 actions, including Create Task, Find Tasks, Get Scores and Get Task. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Trail to Langfuse?
Yes. When something happens in Trail, your agent can act in Langfuse too. This page covers both directions: Trail's triggers and Langfuse's actions are listed here as well.
Do I have to build a connector for Langfuse or Trail?
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 Langfuse and Trail 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.
