Claude Code reads its MCP servers from .mcp.json under the mcpServers key. You rarely open the file. `claude mcp add` writes it, `claude mcp list` and `claude mcp get <name>` read it back with a health check, `claude mcp add-json <name> '<json>'` takes a whole config object, and `/mcp` in a session shows what is connected. No restart. The entry is picked up in the next session, and `/mcp` reconnects one on demand.
| Scope | Path |
|---|---|
| local (default) | ~/.claude.json, this project only |
| project | .mcp.json at the repository root |
| user | ~/.claude.json, every project |
The `--` is load-bearing: it separates Claude Code's own options, such as --transport, --env and --scope, from the command that runs the server. And the default scope is local, private to you and to the directory you ran it in, so adding it in the wrong folder leaves the tools absent with no error at all.
