A Model Context Protocol (MCP) server implemented in Python using FastAPI and CockroachDB.

---

## 🧠 What This Is

`crdb-mcp-server` is a production-grade, spec-aligned MCP server that:

- Implements the [Model Context Protocol](https://modelcontextprotocol.io/introduction)
- Uses **CockroachDB** as a resilient, SQL-compatible backend
- Exposes full **CRUD APIs** for managing model contexts
- Stores context definitions as **JSONB**, allowing arbitrary input/output schema
- Works seamlessly with the [`crdb-mcpctl`](https://github.com/viragtripathi/crdb-mcpctl) CLI

---

## ✅ Feature Highlights

- ✅ REST API for MCP context management (`/contexts`)
- ✅ Schema bootstrapping via CLI flag or env var
- ✅ CRDB URL auto-detection and dialect fix
- ✅ ASCII banner and version info
- ✅ Structured logging and configurable log level
- ✅ Ready for `/run`, `/deploy`, `/evaluate` extensions

---

## 🚀 Quickstart

### 📦 Install from PyPI

```bash
pip install crdb-mcp-server
````

### 🏃 Run with schema init

```bash
crdb-mcp-server serve --init-schema --log-level INFO
```

Or:

```bash
export MCP_AUTO_INIT_SCHEMA=true
crdb-mcp-server serve
```

> Server runs at `http://localhost:8081` by default

---

## 🔧 CLI Usage

```bash
crdb-mcp-server serve --init-schema
crdb-mcp-server serve --port 8081 --host 127.0.0.1 --reload
crdb-mcp-server --version
crdb-mcp-server --banner
```

---

## 🔐 Configuring the Database

### ✅ Set the `CRDB_URL` environment variable

```bash
export CRDB_URL="postgresql://root@localhost:26257/defaultdb?sslmode=disable"
```

> Automatically rewritten to `cockroachdb://...` under the hood for compatibility.

Alternatively, set it directly:
