Connect Le Chat to your Snowflake database

Le Chat queries your Snowflake data through Myriade's MCP server: with business context, read-only, under each user's access rights.

Prerequisites

• A Myriade account on app.myriade.ai (or on your self-hosted instance).
• Network access from Myriade to Snowflake, with a read-only account.
• Le Chat, on a plan that allows custom MCP servers (see the note in step 2).

1. Connect Snowflake to Myriade

Myriade connects to your Snowflake account and supports key-pair authentication, with an encrypted key or not. A client-side query timeout can be set per connection.

Best practice: use a dedicated role with USAGE on the warehouse, database and schemas, and SELECT on the tables.

2. Add Myriade to Le Chat

Le Chat, Mistral's assistant (now called Vibe), supports custom MCP connectors added by URL, with OAuth or a bearer token.

1. 1Take the Myriade MCP address: https://app.myriade.ai/mcp.
2. 2Open Connectors → Add Connector → Custom MCP Connector, then enter a name without spaces and this URL.
3. 3Click Connect: authentication is detected automatically, then sign in to Myriade.

https://app.myriade.ai/mcp

Only admins add custom connectors (on Free, Pro and Student plans, the account owner is the admin). Each tool call asks for approval by default.

Self-hosted Myriade (optional): replace app.myriade.ai with your instance's host.

3. Check the connection

Ask Le Chat a few questions:

• “Which tables describe customer orders in Snowflake?” The assistant searches the Myriade catalog before writing SQL.
• “What was revenue by region last quarter?” Read-only SQL, run under your access rights, saved in Myriade.
• “Did any alert fire on our KPIs this week?” The assistant reads Myriade's checks and alerts.

What Myriade enforces

• INSERT, UPDATE, DELETE, DROP… blocked; a query that cannot be parsed is rejected
• Maximum duration per query and a cap on concurrent queries
• At most 50 rows returned to the assistant
• Database visibility, team rules on tables and columns
• Protected columns stay masked, including for the assistant
