~/.claude.json
json
{
"mcpServers": {

],
"env": {
"SERPER_API_KEY": "<SERPER_API_KEY>"

Gotchas
Claude Code stores MCP servers under an "mcpServers" object in ~/.claude.json. It also reads a project-scoped .mcp.json and supports adding servers from the command line with "claude mcp add". Each entry must declare either a "type" or a "command"; Claude Code refuses an entry that has neither. Remote servers connect natively over Streamable HTTP with OAuth.
