Connect PostgreSQL to ChatGPT Custom GPT
Enable ChatGPT to access your PostgreSQL data through secure, governed MCP servers—no manual queries or engineering bottlenecks
How it works
1. Connect your database
Provide your PostgreSQL connection details. We'll securely connect to your data source.
2. Define your MCP tools
Configure the tools and data available to your AI agents.
3. Deploy your MCP server
We convert your config into a production-ready MCP server with enterprise governance.
How to connect
Connect your PostgreSQL database
- •Database host and port: Your PostgreSQL server endpoint
- •Database name and credentials: Database name, username, and password for authentication
- •Configure data access: Define which tables and queries are available to AI agents
- •Automatic deployment: We deploy your MCP server with enterprise governance—no manual setup required
Link your PostgreSQL MCP to ChatGPT Custom GPT
- 1.Open ChatGPT and create a new Custom GPT
- 2.Navigate to Configure → Actions
- 3.Add your MintMCP Gateway URL as an action endpoint
- 4.Authenticate once with OAuth—credentials are securely managed
- 5.Start querying your PostgreSQL data through conversation

One-time setup connects PostgreSQL to all your AI tools
What you get
Faster deployment
Define your PostgreSQL connection once, then add more MCP tools as needed through simple config updates. No code required.
Rapid iteration
Build team or use-case specific tools rapidly by adding new queries and parameters to your config. Deploy updates in minutes, not days.
Enterprise governance
All database access goes through MintMCP Gateway with full observability, authentication, rate limiting, and audit trails.
Why MintMCP gateway
Centralized governance
Unified authentication, audit logging, and rate control for all database MCP connections.
One-click deployment
Instantly enable database MCP for AI teams via MintMCP's standardized gateway without manual server setup.
OAuth + SSO enforcement
Automatic enterprise authentication wrapping for database MCP endpoints.
Host stdio servers on MintMCP instead of running locally
Containerized servers become accessible to clients like ChatGPT without local installations. Better risk management and security posture without requiring users to run servers on their machines.
Observability and control
Real-time dashboards for monitoring usage, detecting anomalies, and maintaining SLA compliance.
Enterprise hardening
High availability, security, and compliance alignment transform MCP from developer utility to production-grade infrastructure.
Supports shared and per-user auth
Flexibility to configure service accounts at the admin level or enable individual OAuth flows. Secrets remain protected while users gain access, with centralized revocation capabilities.
Granular tool access control
Configure tool access by role. For example, enable read-only operations and exclude write tools like create and delete.
Use cases
Conversational access to transactional data
Enable teams to query customer orders, inventory, and product catalogs through natural language without writing SQL—letting AI agents answer business questions from your PostgreSQL data.
AI and vector search with pgvector
Build semantic search, RAG applications, and recommendation engines by storing vector embeddings alongside relational data with the pgvector extension.
AI-powered geospatial analysis
Let AI agents query location data, calculate routes, and analyze geographic patterns using natural language—accessing PostGIS geospatial capabilities without GIS expertise.
Other supported databases
Connect to 30+ other database types including SQL, NoSQL, and cloud-native databases
FAQs
Yes. MintMCP Gateway is SOC 2 compliant and uses OAuth-based authentication for all database MCP interactions.
