> **Semantic intelligence layer for SQL Server databases, exposed via MCP.**
> Not a SQL executor — a database understanding engine for AI agents.

AI agents don't need raw `execute_sql`. They need to understand schema structure, relationships, object dependencies, and — most importantly — to operate inside a safety boundary that an operator can define.

`sqlserver-semantic-mcp` provides all of this through 12 MCP tools, 1 concrete MCP resource, and 5 MCP resource templates, backed by a two-tier SQLite cache for speed and a JSON-based policy system for safety.

## Quick Start

Pick the path that matches your client. All paths use [`uvx`](https://docs.astral.sh/uv/) — no `git clone`, no virtualenv, no manual install. `uvx` downloads and runs the package on demand and caches it for next time.

> **Prerequisite:** Install [uv](https://docs.astral.sh/uv/getting-started/installation/) once (`curl -LsSf https://astral.sh/uv/install.sh | sh`). Python 3.11+ is fetched automatically by `uv` if needed.

> **Replace** `localhost` / `YourDatabase` / `sa` / `YourPassword` in every example with your real SQL Server credentials.

### 🤖 Claude Code CLI

One command registers the server. `uvx` resolves and caches `sqlserver-semantic-mcp` on first use:

```bash
claude mcp add sqlserver-semantic -- uvx sqlserver-semantic-mcp \
  -e SEMANTIC_MCP_MSSQL_SERVER=localhost \
  -e SEMANTIC_MCP_MSSQL_DATABASE=YourDatabase \
  -e SEMANTIC_MCP_MSSQL_USER=sa \
  -e SEMANTIC_MCP_MSSQL_PASSWORD=YourPassword
```

Or commit the config to your repo as `.mcp.j…
