# Developers

REST API, API keys and scopes, the cmp command-line tool and the MCP server.

- [REST API](https://nexcmp.com/docs/developers/api/) — Call the customer API of your NexCMP installation: authentication, the interactive reference, OpenAPI and Postman downloads, errors, rate limits, idempotency and curl examples.
- [API keys and scopes](https://nexcmp.com/docs/developers/api-keys/) — How customers create API keys (vk_ prefix), choose scopes, limit them by IP and expiry, and how administrators review and revoke them.
- [cmp command-line tool](https://nexcmp.com/docs/developers/cmp-cli/) — Install and use the cmp CLI served by your own panel: browser login with a one-time code, commands generated from the API, output and exit codes, CI use and signed updates.
- [MCP server](https://nexcmp.com/docs/developers/mcp/) — Connect AI assistants (Claude, Cursor, VS Code and others) to your installation's API through the built-in MCP endpoint at /mcp — authentication, client configuration, tools and safety rules.
