Install MySQL Legacy MCP in Claude Code
What you need first
- Claude Code, installed.
- Node.js, which
gives the
npxcommand the server starts with. - Your own values for
YOUR_MYSQL_LEGACY_HOST,YOUR_MYSQL_LEGACY_USER,YOUR_MYSQL_LEGACY_PASSWORD.
Steps
- Run this in a terminal, in the project folder. It adds the server for you in that
project; put
--scope userafterclaude mcp addto have it in every project.
claude mcp add --env MYSQL_LEGACY_HOST=YOUR_MYSQL_LEGACY_HOST --env MYSQL_LEGACY_USER=YOUR_MYSQL_LEGACY_USER --env MYSQL_LEGACY_PASSWORD=YOUR_MYSQL_LEGACY_PASSWORD --transport stdio mysql-legacy-mcp -- npx -y [email protected] - Replace
YOUR_MYSQL_LEGACY_HOST,YOUR_MYSQL_LEGACY_USER,YOUR_MYSQL_LEGACY_PASSWORDwith your own values. - Start Claude Code and type
/mcp: the server is listed with its state.
Check it worked
Ask Claude Code: List the tools of mysql-legacy-mcp.
If it does not start
- spawn npx ENOENT
- Node.js is not on the PATH that Claude Code sees. Install it, or write the
full path of
npxin the config. - The server starts, but its tools fail
- A
YOUR_…placeholder is still in the config, or its value is wrong.
