Purpose

Add a new MCP server the safe way: user scope by default so your custom MCP survives Dex updates.

When to Use

You want to add an MCP server without touching
```
.mcp.json
```
You want it to work across all projects (user scope)
You are not sure which scope to pick

Default Behavior (Recommended)

Use user scope unless you explicitly want to share with a team.

User scope (recommended)

claude mcp add --scope user <server-name> -- <command> <args>

Why: Survives Dex updates and applies across all projects.

Project scope (team-shared)

claude mcp add --scope project <server-name> -- <command> <args>

Why: Stored in

.mcp.json

and shared with everyone on this repo.

Examples

Add a local stdio MCP (user scope)

claude mcp add --scope user gmail --transport stdio -- node .scripts/mcp/gmail-mcp.js

Add a remote HTTP MCP (user scope)

claude mcp add --scope user notion --transport http https://mcp.notion.com/mcp

Add a project-shared MCP (explicit)

claude mcp add --scope project github --transport http https://api.githubcopilot.com/mcp/

Guardrails

If you are not sure, use user scope.
Only use project scope if everyone should get the server.
Do not add personal MCPs to
```
.mcp.json
```
.
