Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

NameDescription
ATLAS_DATASOURCE_URL
Optional, secret		Analytics datasource URL (postgres, mysql, clickhouse, snowflake, duckdb, bigquery, salesforce). Optional — falls back to a bundled NovaMart SQLite demo when unset.
ATLAS_PROVIDER
Optional		LLM provider: anthropic, openai, bedrock, ollama, openai-compatible, gateway. Optional — the MCP server does not call an LLM directly (the client does); set this only if you also run Atlas's chat or scheduler.
ATLAS_API_URL
Optional		URL of a running Atlas API. Optional — defaults to http://localhost:3001. When set, the MCP server inherits the API's connections, semantic layer, and governance.
