Postgres MCP server
Give AI agents governed access to the Postgres MCP server through one audited gateway. Scoped permissions, full observability, and tamper-evident logs on every tool call.
What is the Postgres MCP server?
The Postgres MCP server is an open Model Context Protocol (MCP) server that connects AI agents to a PostgreSQL database. Through it an agent can run queries, inspect schema, and read statistics without bespoke integration code, while the Averta MCP Gateway keeps every query scoped and audited.
postgres-execute-query
Run SQL queries against the database.
postgres-list-tables
List tables across schemas.
postgres-describe-table
Read a table's columns and types.
postgres-list-schemas
List schemas in the database.
postgres-explain-query
Read the query plan for a statement.
postgres-table-stats
Read row counts and table sizes.
postgres-list-indexes
List indexes on a table.
postgres-sample-rows
Read a sample of rows from a table.
postgres-list-connections
Read active connections and activity.
postgres-list-roles
List roles and their privileges.
Why the Averta MCP Gateway
Centralized governance
Unified authentication, audit logging, and rate control for every Postgres MCP connection.
Observability and control
Real-time visibility into usage, anomalies, and SLA compliance across every request.
One-click deployment
Enable the Postgres MCP server for your AI teams through one governed gateway, with no manual setup.
Enterprise hardening
High availability, security, and compliance alignment turn MCP from a developer utility into production-grade infrastructure.
OAuth and SSO enforcement
Enterprise authentication and SSO applied automatically to every Postgres endpoint.
Shared and per-user auth
Configure service accounts or per-user access, with secrets protected and centralized revocation.
One managed endpoint
Connect agents to Postgres through a single governed endpoint instead of locally run servers, improving your security posture.
Granular tool access control
Allow only the tools each role needs. Enable read-only access and block write tools like create and delete.

Your ownBuilt for enterprise teams.
Cloud, private VPC, embedded SDK, or gateway integration. Run Averta where your data, policies, and auditors need it.
Cloud (SaaS)
Fully managed by Averta. Fastest path to production, no infrastructure to run.
Private / VPC
Deploy in your own environment, so data never leaves your boundary.
Embedded SDK & Proxy
Drop Averta into your stack at the SDK or proxy layer, wherever your agents run.
Gateway Integration
Route agent traffic through the gateway, so policy and audit apply at the edge.

Postgres MCP server, answered
Security and setup questions teams ask before connecting the Postgres MCP server to AI agents.
Yes. The Averta MCP Gateway sits between your AI agents and any MCP server, giving each agent scoped, per-agent permissions, applying allow, escalate, or block policies on every tool call, and recording a tamper-evident audit of every action. The “Why the Averta MCP Gateway” section on this page covers what it enforces.
It is as safe as the controls around it. The server can run SQL against your data through one connection, so unscoped access is the real risk. The Averta MCP Gateway enforces read-only or per-table limits and records every query.
Apply tool-level policy through the Averta MCP Gateway so reads run automatically while writes, schema changes, and deletes escalate for approval. Every statement is logged.
Route agents through Averta's MCP Gateway for scoped per-agent permissions, tool-level policy, and tamper-evident audit across every Postgres action.
There are several Postgres MCP servers, including the reference implementation and community projects like crystaldba/postgres-mcp (Postgres MCP Pro). Whichever you run, routing it through the Averta MCP Gateway is what enforces read-only or per-table limits with a tamper-evident audit trail.
Any MCP-compatible client, including Claude and Claude Code, can connect to the Postgres MCP server. Pointing those clients at the Averta MCP Gateway instead of the raw server adds scoped permissions, approval policies, and a tamper-evident log without changing the client setup.
