Frequently asked questions

How do I connect MCP Server to Claude Code?

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 Code using the setup shown above. Once both are done, Claude Code can query your MCP Server data directly.

What MCP Server data can Claude Code access?

Claude Code 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 Code's servers?

Query results are returned to Claude Code 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 Code will be able to query all of them.
