Connect PostgreSQL MCP to your AI Agents
Query your PostgreSQL database in plain English. No SQL required.
Everything you can ask your agent about your PostgreSQL data.
Ask in plain English — Sequel translates it into a PostgreSQL query, runs it, and your agent hands back the answer. No SQL, no dashboards, no CSV exports.
Connect to your agent- How many rows are in each table?
- Show me the 10 most recently created users
- What's the average order value by customer segment?
- Which products have never been ordered?
- Show me monthly revenue broken down by plan type
Install
Install PostgreSQL MCP in your agent
Pick your app and Sequel installs itself: a one-click link where the client supports it, that client’s own few steps where it doesn’t. Every route signs in with your Sequel account over OAuth, so there is no API key to copy and nothing to keep in sync.

Can we trust our product metrics
Two tools show different numbers for the same metric and nobody knows which to trust. Reconciles the disputed figure against a system of record such as Stripe or the application database, then finds the instrumentation defect behind it: duplicate and near-duplicate event names, events that silently stopped firing, missing properties and system-fired events counted as user actions.
Dispute and refund risk monitor
Track chargeback and dispute activity and refund rate against the Visa VAMP and Mastercard ECM thresholds that get a payment account fined or shut off, and find which products, plans or cohorts generate them. Covers dispute rate versus dispute activity, per-network denominators and dispute-fighting economics.
Failed payment and involuntary churn audit
Separate customers who chose to leave from cards that simply declined: failed payments, declined renewals and involuntary churn, and where in the dunning and retry sequence the recovery is being lost. Covers involuntary churn share, first-attempt failure rate, payment recovery rate, decline codes and which accounts are sitting in dunning right now.
Feature launch impact readout
Measure whether a feature we just shipped actually landed: adoption against an eligible denominator of users who could even reach it, breadth, depth and sustained use after the release, a pre and post impact estimate with or without a control group, and a keep, iterate or sunset call.
Find our activation moment
Discover the aha moment: which early in-product action, taken in the first session or first week, most separates users who stay from users who vanish, how to score candidate first actions by retention lift, and what share of new signups ever reach it. Covers activation metric definition, activation rate and time to value.
Is our retention curve flattening
Do users keep coming back, or do they drift away after the first week or month? Builds the cohort retention curve for your key action at its natural frequency and judges whether it flattens to a plateau or decays to zero, covering N-day versus unbounded retention, repeat usage, leaky bucket diagnosis and how the plateau compares to published benchmarks.

Frequently asked questions
How do I connect my PostgreSQL database?
Click 'New Connection', select PostgreSQL, and enter your host, port, database name, username, and password. Sequel will test the connection before saving. Make sure your database allows connections from Sequel's IP range.
Is my database connection secure?
All connections use SSL/TLS by default. Credentials are encrypted at rest and never exposed in query results or logs. Sequel uses a read-only connection by default and will not execute write statements.
Can Sequel modify my data?
No. Sequel is read-only by default and will warn you if a query could modify data. The agent is explicitly instructed never to run INSERT, UPDATE, DELETE, or DDL statements unless you explicitly request and confirm it.
What PostgreSQL versions are supported?
Sequel supports PostgreSQL 12 and above. Older versions may work but are not officially tested.
Can I connect a cloud-hosted PostgreSQL database?
Yes. AWS RDS, Supabase, Railway, Neon, Google Cloud SQL, and other cloud PostgreSQL providers all work. You may need to allow Sequel's IP in your database firewall rules.
Does Sequel understand my schema automatically?
Yes. When you connect, Sequel reads your table names, column names, types, and relationships. It uses this schema to write accurate SQL and avoid hallucinated column names.
