PostgreSQL MCP Server
Connect Claude to your PostgreSQL database with one secure URL. No local MCP server to configure, no .env files, no setup per device. Synra manages the connection — encrypted, read-only, and logged.
✓ Works with any Postgres host · ✓ Read-only by default · ✓ Free to try
Compatibility
Works with any PostgreSQL host
Any PostgreSQL-compatible database works. Synra doubles as a Neon MCP server, a Supabase MCP server, and an MCP gateway for any other Postgres host. If you have a connection string, Synra can connect.
How it works
Four steps. Under a minute.
Get your PostgreSQL credentials
Connection string, host, port, database name, and password — from Neon, Railway, AWS RDS, or wherever your Postgres runs.
Add to Synra
Paste your credentials into the Synra dashboard. We encrypt everything with AES-256 and generate your MCP endpoint URL.
Copy your URL
One secure URL that works everywhere — Claude Desktop, Claude.ai, or any MCP-compatible client.

Ask Claude anything about your PostgreSQL database in plain English. Tables, schemas, queries — all read-only, all logged.
Try it
What you can ask Claude
"What tables are in my Postgres database?"
Lists all tables, columns, and types from your PostgreSQL schema
"Show me users who signed up this week"
Runs a SELECT with date filtering on your users table
"Which customers have the highest lifetime value?"
Aggregates revenue data across your orders and customers tables
"Describe the relationships between my tables"
Maps foreign keys and shows how your Postgres tables connect

Why not self-host?
| Self-hosted Postgres MCP | Synra | |
|---|---|---|
| Setup | Install locally, configure JSON, manage .env | One URL, under 60 seconds |
| Credentials | Plaintext on disk | AES-256 encrypted |
| Safety | No guardrails by default | Read-only, SQL sanitization |
| Devices | Reconfigure per machine | Same URL everywhere |
| Logging | None | Full audit trail |

FAQ
PostgreSQL MCP FAQ
What is a PostgreSQL MCP server?
A PostgreSQL MCP server connects AI assistants like Claude to your Postgres database using the Model Context Protocol (MCP). It translates natural language questions into SQL queries and returns results. Synra is a managed PostgreSQL MCP server — instead of running one locally, you get a single secure URL that works on any device.
Which PostgreSQL hosts does Synra work with?
Any PostgreSQL-compatible database. This includes Neon, Railway, AWS RDS, Render, DigitalOcean, Supabase, Heroku, Crunchy Bridge, Aiven, Fly.io, Timescale Cloud, Google Cloud SQL, Azure Database for PostgreSQL, and any self-hosted Postgres instance. If you have a connection string, Synra can connect.
Does Synra work as a Neon MCP server?
Yes. Neon is built on PostgreSQL and speaks the standard Postgres wire protocol, so Synra works as a Neon MCP server out of the box. Copy your Neon connection string from the Neon dashboard, paste it into Synra, and Claude can query your Neon database in plain English. Branches, autoscaling, and scale-to-zero compute all work transparently — Synra just sends the query, Neon handles the rest.
Can Claude write to my PostgreSQL database?
No. Synra enforces read-only access by default. Only SELECT queries are allowed. INSERT, UPDATE, DELETE, DROP, ALTER, and other write operations are blocked at the gateway level before they reach your database.
How is this different from the official Postgres MCP server?
The official Postgres MCP server from Anthropic runs locally on your machine. You configure it with a JSON file containing your database credentials in plaintext. Synra is a managed alternative — your credentials are encrypted, access is read-only by default, every query is logged, and one URL works across all your devices and team members.
Is there a free trial?
Yes. Sign up and test your PostgreSQL connection for free. Subscribe when you're ready for full access.
