Deploy and Host Agentic Data Stack Lite (Langfuse Cloud) on Railway

A self-hosted, observability-first agentic chat platform combining LibreChat (multi-provider LLM chat with MCP tool support), Langfuse Cloud (full trace observability), and a ClickHouse MCP server pre-wired to the public ClickHouse demo cluster.

About Hosting Agentic Data Stack Lite (Langfuse Cloud)

This template deploys five Railway services: LibreChat with its admin panel and MongoDB store, ClickHouse, and a ClickHouse MCP server that exposes ClickHouse's public sql-clickhouse.clickhouse.com demo cluster to LibreChat's agents. After deploy, you sign into LibreChat and start chatting with agents that can query the ClickHouse demo data out of the box, OAuth into your own ClickHouse Cloud account via the ClickHouse Cloud MCP, or bring your own MCP servers. Every agent run streams traces to a configurable Langfuse Cloud project for inspection, scoring, and evaluation.

Common Use Cases

• Self-hosted ChatGPT-style frontend with multi-provider LLM support and per-trace observability

• First-touch demo environment for ClickHouse Cloud combined with agentic SQL workflows

Dependencies for Agentic Data Stack Lite (Langfuse Cloud) Hosting

• At least one LLM provider API key
• Optional: a ClickHouse Cloud account to point the ClickHouse Cloud MCP at your own data
