Connect a client

Add the LoginWith MCP server to Claude Code or any MCP client.

Claude Code

claude mcp add --transport http loginwith https://mcp.loginwith.dev/mcp

Then run /mcp in Claude Code and authenticate loginwith. A browser opens on the LoginWith console sign-in.

Any client that speaks Streamable HTTP and the MCP authorization spec works the same way: give it the URL and nothing else.

https://mcp.loginwith.dev/mcp

No client id, no secret, no token to paste — the client discovers the authorization server and registers itself. See Authentication.

@loginwith/mcp runs the same tools as a local stdio server (bin: loginwith-mcp), presenting an access token you give it.

Variable	What
`LGW_API`	Your API origin, e.g. `https://acme.loginwith.dev`. Required
`LGW_ACCESS_TOKEN`	A user access token. Every tool presents it as-is

claude mcp add loginwith \
  --env LGW_API=https://acme.loginwith.dev \
  --env LGW_ACCESS_TOKEN=<a user access token> \
  -- npx -y @loginwith/mcp

Logs go to stderr; stdout is the protocol channel.
