Let Claude and ChatGPT query your Microsoft SQL Server database directly using the Model Context Protocol (MCP). Supports SQL Server 2016+, Azure SQL Database, and Windows Authentication. No backend code required.
Create a free account at conexor.io/register — no credit card required. The free tier includes one database connection and 1,000 queries per month.
Install the Conexor agent on Windows or Linux — any machine that can reach your SQL Server instance. The agent connects outbound only, so no firewall changes are needed.
Provide your SQL Server connection details. Both SQL Authentication and Windows Authentication are supported. We recommend a dedicated read-only user.
Conexor reads your SQL Server schema — tables, columns, types, and relationships — and generates MCP tools for each table automatically.
Copy the MCP server URL from your Conexor dashboard. Open Claude Desktop → Settings → MCP Servers → Add Server. Paste the URL and start querying.
If your SQL Server uses Windows Authentication, install the Conexor agent on a domain-joined machine. The agent will use the machine's Active Directory credentials — no username or password needed in the connection string.
“How many active users do we have?”
→ Queries users table
→ Returns the count from your users table
“What were our top 5 products by revenue last month?”
→ Complex GROUP BY query
→ Returns your top products ranked by revenue
“Show me customers who haven't ordered in 90 days”
→ Joins orders + customers tables
→ Lists inactive customers with last order dates
“What's the average order value by country?”
→ Aggregate query across orders
→ Returns average order values grouped by country
AI can only read your data. INSERT, UPDATE, DELETE, and DDL statements are blocked at the protocol level.
Database credentials are AES-256 encrypted at rest. They never leave your infrastructure when using the on-premise agent.
Every AI-generated query is logged with timestamp, user, and results. Review any query from your dashboard.
Free tier includes 1 database connection and 1,000 queries/month. No credit card required.
