Let Claude query your PostgreSQL database directly — ask questions in plain English and get answers from live data. No backend code, no API wrappers, no stale exports.
Claude can reason about revenue, churn, activation, support load, and product usage. What it cannot do on its own is know that your subscriptions_v2 table is where plan changes live, or that trial accounts should exclude internal test tenants.
A PostgreSQL MCP server gives Claude a structured, scoped way to discover your schema and answer questions from live data — without making engineering build a custom API for every new report.
Sign up at conexor.io — no credit card required. The free tier includes one database connection and 1,000 queries per month.
Create a dedicated PostgreSQL user with SELECT access to the schemas Claude should be allowed to inspect, then add that connection in Conexor. This keeps AI access scoped from the start.
Conexor generates an MCP server with tools for each table. Copy the server URL and API key from your dashboard.
Open Claude Desktop → Settings → MCP Servers → Add Server. Paste your MCP server URL. Claude can now use the PostgreSQL tools and discovered schema exposed through Conexor.
Open a new conversation and ask: "What were our top 10 customers by revenue last quarter?" Claude queries your PostgreSQL database and returns the answer.
Claude needs table names, columns, relationships, and types before it can answer database questions reliably.
Fields like status, plan_id, tenant_id, and created_at only become useful when the MCP layer exposes enough context to avoid guessing.
The goal is not raw database access. It is controlled, auditable tools that answer questions from the right PostgreSQL data.
Ask Claude things like "Which customers expanded last month?" or "What is MRR by plan?" and get answers directly from live PostgreSQL data.
Let engineers and PMs inspect events, failed jobs, signup funnels, or region-level performance without waiting on manual SQL from the data team.
Use Claude as a flexible query layer when the question changes too often for static dashboards to keep up.
Keep access read-only by default, with audit logs and scoped credentials, instead of exposing raw database access to every workflow.
Use a dedicated read-only PostgreSQL user rather than an admin or application owner account.
Limit access to the schemas and tables Claude actually needs for reporting or operational questions.
Start with SELECT-style workflows before considering any action that changes data.
Keep audit logs enabled so teams can review what was asked and which tools were used.
Document which business terms map to important PostgreSQL tables, especially for revenue, activation, and customer health.
