LangGraph

Airia discovers the assistants (agents) and their graphs on a deployed LangGraph server and adds them to the inventory.

Authentication model

A LangSmith API key plus the URL of your LangGraph deployment.

Two things to get right, because they are the most common setup mistake:

• The URL is the deployment's own server URL, not the LangSmith website. Airia calls the LangGraph Server API directly (it searches /assistants on that host). A LangGraph Platform deployment URL looks like https://<deployment-name>.<region>.langgraph.app; a self-hosted server is whatever host you run it on. https://api.smith.langchain.com (the LangSmith control plane) is not a valid value — it returns 404 on the assistants API and the connection test fails.
• The API key is a LangSmith API key (starts with lsv2_pt_ for a personal token or lsv2_sk_ for a service key), created under LangSmith Settings → API Keys. Airia sends it to the deployment as the x-api-key header.

Customer-side setup steps

1. Identify the LangGraph deployment you want discovered and copy its server URL (from the LangSmith Deployments page, or your self-hosted host).
2. In LangSmith, Settings → API Keys → Create API Key (Personal Access Token is fine), copy the lsv2_... value.
3. In Airia, go to Discover → Connections → LangGraph and create a new connection with the deployment URL and the API key.

Multiple environments

Multiple LangGraph connections per tenant are supported: one per deployment.
