Connect your data to Claude Code
Query your databases directly from the Claude Code CLI — without leaving your terminal.
What Claude Code can do with Sequel
Database access from the terminal
Claude Code can now query your databases as part of agentic coding sessions. Ask it to check schemas, pull sample data, or verify data assumptions — all without leaving the terminal.
Data-aware code generation
When Claude Code knows your actual schema through Sequel, it generates more accurate SQL, migrations, and ORM models — grounded in what's really in your database, not guesses.
Works in any Claude Code session
Once added via CLI, Sequel tools are available in every Claude Code session — interactive, one-shot, or automated. No per-project setup needed.
Everything you can ask Claude Code about your data.
Ask in plain English. Sequel turns it into a query, runs it read-only, and Claude Code hands back the answer. No SQL, no dashboards, no CSV exports.
Connect Claude Code- What tables exist in our database and what do they store?
- Show me the schema for the `orders` table
- Find all foreign key constraints in our production database
- How many rows are in each table?
- What's the distribution of `status` values in `payments`?
Setup
Add Sequel to Claude Code
Drop the Sequel MCP server into Claude Code, then ask it anything about your connected data. Sequel is read-only by default and shows each query before it runs.
claude mcp add (CLI)
claude mcp add --transport http sequel https://api.sequel.sh/mcp \
--header "Authorization: Bearer sql_your_api_key"Install
Install Sequel MCP in Claude Code
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

Frequently asked questions
How do I add Sequel to Claude Code?
Run the `claude mcp add` command shown above in your terminal. Replace `sql_your_api_key` with a key from Settings → API Keys. The server is added at the default `local` scope (current project only).
How do I make Sequel available across every project?
Add the `--scope user` flag: `claude mcp add --scope user --transport http sequel https://api.sequel.sh/mcp --header "Authorization: Bearer sql_your_api_key"`. User-scope servers are available in every Claude Code session on this machine.
Can I verify Sequel is connected?
Run `claude mcp list` to see all configured MCP servers, or `claude mcp get sequel` to inspect the Sequel config specifically.
Does this work in Claude Code's non-interactive mode?
Yes. Sequel tools are available in both interactive (`claude`) and non-interactive (`claude -p 'your prompt'`) modes. They're also available when using Claude Code via the SDK.
Can I add Sequel to a specific project only?
Yes. Use the `--scope project` flag: `claude mcp add --scope project --transport http sequel https://api.sequel.sh/mcp --header "..."`. Project-scope servers are stored in `.mcp.json` at the repo root and shared with anyone who clones the repo.
