Find and build MCP servers

Browse reviewed connectors in the Anthropic Directory. Directory connectors use the same MCP infrastructure as Claude Code, so you can add any remote server listed there with claude mcp add.

Verify you trust each server before connecting it. Servers that fetch external content can expose you to prompt injection risk.

To build your own server, see the MCP server guide for protocol fundamentals and the Claude connector building docs for authentication, testing, and Directory submission.

You can also have Claude scaffold a server for you with the official mcp-server-dev plugin.

In a Claude Code session, run:

```
/plugin install mcp-server-dev@claude-plugins-official
```

If the install fails, match the message Claude Code reports:

* `Marketplace "claude-plugins-official" not found`: add the marketplace with `/plugin marketplace add anthropics/claude-plugins-official`, then retry the install.
* The plugin is [not found in the marketplace](https://code.claude.com/docs/en/discover-plugins#install-plugins): check the plugin name.

If the install summary reports `Run /reload-plugins to activate.`, Claude Code then runs that reload for you. If the reload warns that your next message would re-read the conversation, run `/reload-plugins --force`.

```
/mcp-server-dev:build-mcp-server
```

Claude asks about your use case and scaffolds a remote HTTP or local stdio server.
