### Description (declared)

# sql-server-mcp

A local MCP server for read-only SQL Server / MS Fabric queries. Runs as a
single-user process over stdio, authenticated as *you* (delegated Entra ID
identity, not a service principal) — **one server process per
tenant**. 

## Prerequisites

- Python 3.14+ and [uv](https://docs.astral.sh/uv/)
- Either the [Azure CLI](https://learn.microsoft.com/cli/azure/install-azure-cli) logged in to the target tenant (`az login --tenant <tenant-id>`), or just a browser available — the server falls back to an interactive browser login if there's no CLI session
- An Entra ID account in the target tenant with read access to the target database (e.g. `db_datareader`)

## Configuration

Each tenant gets its own set of environment variables:

| Variable | Required | Description |
|---|---|---|
| `MCP_SQL_SERVER_NAME` | yes | SQL Server / Fabric SQL endpoint hostname, e.g. `xyz-xyz.datawarehouse.fabric.microsoft.com` |
| `MCP_SQL_DATABASE_NAME` | yes | Default database to connect to |
| `MCP_AZURE_TENANT_ID` | yes | The Entra ID tenant ID — pins auth to this directory even if your machine has other `az login` sessions active |
| `MCP_MAX_ROWS` | no | Max rows returned per tool call (default: 25) |

## Running it

The server is a `uvx`-runnable console script (`sql-server-mcp`), no
manual install step needed - `uvx` builds an isolated environment for it
on first run and reuses it afterwards:

```bash
uvx sql-server-mcp
```

To run from a local checkout instead (e.g. during development), point
`--from` at the path:

```bash
uvx --from /path/to/sql-server-mcp sql-server-mcp
```

On startup it acquires a token (via `az login` if available, otherwise an
interactive browser prompt) and runs over stdio. Database connectivity uses
[`mssql-python`](https://github.com/microsoft/mssql-python), which bundles
its own driver — no separate ODBC driver install is required.

### Example MCP client config

One block per tenant:

```json
{
  "mcpServers": {
    "tenant-a-sql": {
      "…
