About Coalesce MCP Server
Connect your AI to Coalesce, the data transformation platform built for Snowflake with a column-aware approach.
LangChain's ecosystem of 500+ components combines seamlessly with Coalesce through native MCP adapters. Connect 8 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Environment Management — List all environments in your Coalesce organization and inspect their configurations.
- Job Monitoring — Check the status of the last run for any environment and view execution logs.
- Trigger Transformations — Start transformation jobs on demand with optional node selectors to target specific pipelines.
The Coalesce MCP Server exposes 8 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
