Add my server

Install PostgreSQL MCP Server in Claude Code

What you need first

  • Claude Code, installed.
  • uv, which gives the uvx command the server starts with.
  • Your own values for YOUR_POSTGRES_HOST,YOUR_POSTGRES_PORT,YOUR_POSTGRES_USER,YOUR_POSTGRES_DB.

Steps

  1. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.
claude mcp add --env POSTGRES_HOST=YOUR_POSTGRES_HOST --env POSTGRES_PORT=YOUR_POSTGRES_PORT --env POSTGRES_USER=YOUR_POSTGRES_USER --env POSTGRES_DB=YOUR_POSTGRES_DB --transport stdio postgresql-mcp-server -- uvx mdev-postgresql-mcp-server==0.1.2
  1. Replace YOUR_POSTGRES_HOST,YOUR_POSTGRES_PORT,YOUR_POSTGRES_USER,YOUR_POSTGRES_DB with your own values.
  2. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of postgresql-mcp-server.

If it does not start

spawn uvx ENOENT
uv is not on the PATH that Claude Code sees. Install it, or write the full path of uvx in the config.
The server starts, but its tools fail
A YOUR_… placeholder is still in the config, or its value is wrong.
