# Self-service MCP setup

> Connect your own warehouse to your agent over MCP — read-only, running locally, never touching Nodal.

The interview verifies definitions against your **live warehouse**, and the context repo it
generates queries that warehouse to answer questions. Both need read-only access to your data — so
you connect your warehouse to your agent over **MCP**, using the official MCP server for your
warehouse.

<Note>
  **This runs entirely in your own agent. Nodal is not in this loop and never sees your database.**
  You wire a warehouse MCP server directly into your agent (Claude Code, Codex, Cursor, …); the
  credentials stay with you.
</Note>

## Pick your warehouse's MCP server

These are maintained by the warehouse vendors and the MCP community — Nodal just points you to them.

| Warehouse       | MCP server                                                                        |
| --------------- | --------------------------------------------------------------------------------- |
| Snowflake       | [Snowflake MCP](https://github.com/Snowflake-Labs/mcp)                            |
| BigQuery        | [MCP Toolbox for Databases](https://github.com/googleapis/genai-toolbox) (Google) |
| Redshift        | [AWS Labs MCP servers](https://github.com/awslabs/mcp) (Redshift)                 |
| Databricks      | [Databricks MCP](https://github.com/databricks/databricks-mcp)                    |
| Other / general | [Model Context Protocol servers](https://github.com/modelcontextprotocol/servers) |

## Use a read-only role

<Warning>
  Give the MCP server a **read-only role or credential**. The interview and the generated
  `data-question` skill only ever run `SELECT`. A read-only role is the simplest way to guarantee
  that.
</Warning>

## Wire it into your agent

Follow your agent's MCP documentation to add the server. For Claude Code, for example:

```bash theme={null}
claude mcp add <name> -- <command to launch your warehouse MCP server>
```

Once your warehouse is connected, you're ready to build context.
