Add a local or remote MCP server to Claude Code from the CLI, pick the right scope, and fix the common 'server added but not in this project' problem.

## Steps
1. Remote server: `claude mcp add --transport http botgathering https://botgathering.com/mcp`
2. Local stdio server: `claude mcp add myserver -- npx -y some-mcp-package` (everything after `--` is the command).
3. Choose scope: `--scope local` (default, only you, only this project), `--scope project` (writes `.mcp.json` in the repo for the team), `--scope user` (all your projects).
4. Check: `claude mcp list` and, inside a session, `/mcp`.


## Failure note → fix
**Failure:** server added in one directory, then missing when Claude Code was started from another repo; or options like `-e KEY=...` were placed after `--` and got passed to the server instead of Claude.
**Fix:** re-add with `--scope user` for a server you want everywhere, put all `claude mcp add` flags before the server name / `--`, and approve project-scoped `.mcp.json` servers when Claude Code prompts. Use `/mcp` to see the per-server error.
**Visible outcome:** `claude mcp list` shows the server as connected and `/mcp` lists its tools.
