How to Connect PostgreSQL to Muse
Query your PostgreSQL data directly from Muse using Sequel’s MCP server. Ask questions in plain English, with no SQL, no dashboards, and no context switching.
Short answer
Connect PostgreSQL to Sequel, then add Sequel's MCP server to Muse using the config on this page. Muse can then query your live PostgreSQL data in plain English, with no connector code and no CSV exports. Both steps take a few minutes.
Everything you can ask Muse about your PostgreSQL data.
Ask in plain English — Sequel translates it into a PostgreSQL query, runs it, and Muse hands back the answer. No SQL, no dashboards, no CSV exports.
- 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
How it works
Three steps to get started
Connect PostgreSQL to Sequel
In your Sequel dashboard, go to Connections and add PostgreSQL. Sequel handles authentication and schema discovery automatically.
Add Sequel to the agent
Follow the steps below to add Sequel to Muse. It signs in with your Sequel account over OAuth, so there is no key to copy.
Ask Muse about your data
Restart Muse and start asking questions. "How many rows are in each table?" — and get a real answer backed by live PostgreSQL data.
Why Muse
What Muse does with your PostgreSQL data
One message, then it's a saved skill
Muse writes the MCP client itself on its VM, lists Sequel's tools, calls them end to end, and saves the result as a skill. You do not repeat the setup: the next conversation already knows how to reach your data.
A remote server is the shortest path
Muse runs in Meta's cloud, so it can reach a hosted streamable-HTTP server the same way any other client does, and it cannot reach a database on your laptop. Sequel is hosted and connects to your cloud databases and warehouses, which is exactly the shape Muse handles best.
Credentials stay out of the chat
Sign in through Muse's secure credential flow rather than pasting anything into the conversation: secrets live in its Secure Credentials Store and are swapped in at the network boundary. Your database passwords never leave Sequel at all.
Configuration
Add Sequel to Muse
Use it in Muse chat (iOS, Android, muse.ai, WhatsApp). Muse signs in with your Sequel account over OAuth, so there is no API key to paste.
Muse chat (iOS, Android, muse.ai, WhatsApp)
Build a custom connector to Sequel. It is a remote MCP server over streamable HTTP at https://api.sequel.sh/mcp and it uses OAuth, so ask me to sign in through the secure credential flow. Connect to it with the official MCP SDK, test every tool end to end, and save it as a reusable skill so you can answer questions about my data in any conversation.
Install
Install PostgreSQL MCP in Muse
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.
Already have an MCP client?
https://api.sequel.sh/mcp
Add it as a remote (streamable HTTP) server and sign in when prompted. Skills come with it; nothing else to install. Manual setup per client

- 1Paste the message above into Muse. It has no “add MCP server” screen; it builds the connector itself.
- 2Sign in to Sequel when Muse opens its secure credential flow. Never paste a key into the conversation.
- 3Muse tests each tool and saves the integration as a skill, so later chats already have it. Then ask it about your data.

Frequently asked questions
How do I connect PostgreSQL to Muse?
You need two things: (1) connect PostgreSQL to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Muse using the setup shown above. Once both are done, Muse can query your PostgreSQL data directly.
What PostgreSQL data can Muse access?
Muse can access any data available through your PostgreSQL connection in Sequel. Use Sequel's search tool to discover available metrics and dimensions, then execute queries to pull the data you need.
Is my PostgreSQL data sent to Muse's servers?
Query results are returned to Muse as context within your conversation. Only the data you explicitly ask about is retrieved. Sequel never stores your query results permanently — they exist only for the duration of the tool call.
Do I need a Sequel account?
Yes. You need a Sequel account to connect PostgreSQL and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to PostgreSQL and generate an API key from Settings → API Keys.
Can I connect multiple PostgreSQL accounts?
Yes. Sequel supports multiple connections of the same type. If you have multiple PostgreSQL accounts or properties, add each as a separate connection in Sequel. Muse will be able to query all of them.
Can Meta Muse use MCP servers?
Yes, though not through a settings menu. Muse builds a custom connector on its own VM with the official MCP SDK, connects over streamable HTTP, and saves the integration as a skill. Remote servers like Sequel are the easy case; a server on your own laptop is not reachable from Meta's cloud.
How do I add Sequel to Muse?
Send Muse one message naming Sequel, its server URL (https://api.sequel.sh/mcp) and what you want to be able to ask. It will ask whether the server is HTTP or stdio and how it authenticates, build the connector, test the tools, and save the skill. Sign in when it opens the secure credential flow.
Does Muse see my Sequel credentials?
Only if you paste them into the chat, which you should not do. Keys entered through Muse's credential prompt are held by a daemon outside the agent runtime and injected at the network edge. Better still, sign in to Sequel over OAuth: then there is no key at all, and your database passwords stay encrypted in Sequel either way.
Which data sources can Muse query through Sequel?
Any source you have connected in Sequel: PostgreSQL, MySQL, ClickHouse, BigQuery, Snowflake, Google Analytics, Search Console, Google Ads, Meta Ads, HubSpot, Stripe, and more. Muse can only reach the connections your organization has set up.
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.
