Connect ChatGPT to your Snowflake database

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

Standard MCP · not tested by Myriade

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.
ChatGPT, 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 ChatGPT

ChatGPT connects to remote MCP servers added as custom apps. Full MCP support is in beta on the Business, Enterprise and Edu plans, on the web.

1Take the Myriade MCP address: https://app.myriade.ai/mcp.
2In ChatGPT, add a custom MCP server with this URL (through developer mode, depending on your workspace version).
3Choose OAuth, accept the warning, then sign in to Myriade.

https://app.myriade.ai/mcp

ChatGPT only accepts OAuth: myr_… tokens do not work there. On Business, an admin or owner turns the feature on.

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

3. Check the connection

Ask ChatGPT 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

Why connect through Myriade

Frequently asked questions

Can ChatGPT modify or delete data in Snowflake?

No. SQL queries that ChatGPT sends through Myriade's MCP server are parsed before they reach Snowflake: any write (INSERT, UPDATE, DELETE, DROP…) is rejected, even nested in a subquery, and a query that cannot be parsed is refused. As a precaution, also connect Myriade to Snowflake with a read-only account.

Does ChatGPT connect directly to Snowflake?

No. ChatGPT only talks to Myriade's MCP server: Myriade alone holds the Snowflake credentials and runs the queries. On Myriade Cloud, the MCP address is public and Myriade must be able to reach Snowflake. If you choose to self-host Myriade, the connection to Snowflake starts from your own infrastructure, and the MCP address must stay reachable by ChatGPT.

Is ChatGPT compatible with Myriade?

ChatGPT supports remote MCP servers, and Myriade exposes a standard MCP server (Streamable HTTP, OAuth). Myriade has not tested this connection yet: tell us if you try it, we will help you set it up.
