How it works

Three steps to get started

Connect MCP Server to Sequel

In your Sequel dashboard, go to Connections and add MCP Server. Sequel handles authentication and schema discovery automatically.

Add Sequel to the agent

Copy the Sequel MCP configuration into Claude's settings file (shown below). Swap in your API key from Settings → API Keys.

Ask Claude about your data

Restart Claude and start asking questions. "What tools does this MCP server provide?" — and get a real answer backed by live MCP Server data.

Why Claude

What Claude does with your MCP Server data

Ask anything about your data

Claude understands natural language. Just describe what you want to know — "Show me revenue by region for Q1" — and Sequel fetches the data, runs the query, and Claude explains the results in context.

Multi-source analysis in one conversation

Sequel connects to databases, analytics platforms, and SaaS tools. Ask Claude to join your Postgres revenue data with Google Analytics sessions in a single thread — no SQL required.

Python workbench inside the chat

Need a chart or statistical analysis? Claude can run Python code in Sequel's isolated sandbox — pandas, matplotlib, seaborn all included — and return the result directly in your conversation.

Configuration

Add Sequel to Claude

Place this in ~/Library/Application Support/Claude/claude_desktop_config.json and replace sql_your_api_key with a key from Settings → API Keys.

~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "sequel": {
      "url": "https://api.sequel.sh/mcp",
      "headers": {
        "Authorization": "Bearer sql_your_api_key"
      }
    }
  }
}

Install

Install MCP Server MCP in Claude

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

Add Sequel to Claude

One click: the button above opens Claude with Sequel pre-filled, and Claude signs you in with your Sequel account. There is no key to paste.

Frequently asked questions

How do I connect MCP Server to Claude?

You need two things: (1) connect MCP Server to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Claude using the setup shown above. Once both are done, Claude can query your MCP Server data directly.

What MCP Server data can Claude access?

Claude can access any data available through your MCP Server 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 MCP Server data sent to Claude's servers?

Query results are returned to Claude 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 MCP Server and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to MCP Server and generate an API key from Settings → API Keys.

Can I connect multiple MCP Server accounts?

Yes. Sequel supports multiple connections of the same type. If you have multiple MCP Server accounts or properties, add each as a separate connection in Sequel. Claude will be able to query all of them.

Does this work with Claude Desktop and Claude.ai?

The JSON config above works with Claude Desktop (Mac and Windows). Claude.ai supports MCP through Workspaces — go to Settings → Integrations to add the Sequel MCP URL there.

What databases can Claude query through Sequel?

Any database or analytics tool you've connected in Sequel: PostgreSQL, MySQL, ClickHouse, BigQuery, Snowflake, Google Analytics, and more. Claude can only access connections your organization has set up.

Is my database data sent to Anthropic?

Query results are passed to Claude as context within your conversation. Anthropic's standard data handling policies apply. Sequel never stores your query results permanently — they exist only for the duration of the tool call.

Can I limit which connections Claude can see?

Sequel MCP is scoped to your organization's connections. You can create separate API keys for different use cases and revoke them at any time from Settings → API Keys.

What is MCP?

MCP (Model Context Protocol) is an open standard for connecting AI agents to external tools and data sources. Any server that implements the MCP protocol can be connected to Sequel.

How do I connect an MCP server?

Click 'New Connection', select MCP Server, give it a name, and enter the server's HTTP URL. Optionally add any required HTTP headers (like an API key). Sequel will connect and discover available tools automatically.

What types of MCP servers are supported?

Sequel supports HTTP-based MCP servers using the StreamableHTTP transport. This covers the vast majority of publicly deployed MCP servers.

Do I need to configure each tool manually?

No. Sequel auto-discovers all tools by reading the server's manifest. It uses tool names and descriptions to understand what each tool does and when to call it.
