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 the MCP config
Copy the Sequel MCP configuration into OpenClaw's settings file (shown below). Swap in your API key from Settings → API Keys.
Ask OpenClaw about your data
Restart OpenClaw and start asking questions. "How many rows are in each table?" — and get a real answer backed by live PostgreSQL data.
Configuration
Add Sequel to OpenClaw
Place this in ~/.openclaw/openclaw.json and replace sql_your_api_key with a key from Settings → API Keys.
~/.openclaw/openclaw.json
{
"mcp": {
"servers": {
"sequel": {
"url": "https://api.sequel.sh/mcp",
"transport": "streamable-http",
"headers": {
"Authorization": "Bearer sql_your_api_key"
}
}
}
}
}Sequel CLI
Install PostgreSQL MCP to OpenClaw
The Sequel CLI installs PostgreSQL into OpenClaw in one step — it signs you in, provisions a scoped API key, and writes the right config to the right place. No keys to copy by hand.
Prefer npm? npm install -g @sequelsh/cli@latest works too.

Frequently asked questions
How do I connect PostgreSQL to OpenClaw?
You need two things: (1) connect PostgreSQL to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to OpenClaw using the setup shown above. Once both are done, OpenClaw can query your PostgreSQL data directly.
What PostgreSQL data can OpenClaw access?
OpenClaw 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 OpenClaw's servers?
Query results are returned to OpenClaw 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. OpenClaw will be able to query all of them.
