# Add-ons and Integrations

> Reference for Delegate and Cartographer's Add-ons & Integrations area — skills, tools, plugins, MCP servers, connections, credential assets, and hooks.

Delegate and Cartographer share one **Add-ons & Integrations** area, separate from Settings, where you manage what the agent can use and what it's connected to: skills, tools, plugins, MCP servers, connections, credential assets, and hooks. Each part is documented on its own page:

- [Skills](skills.md) — the Skills, Discover skills, and Review queue views
- [Tools](tools.md) — local tools, web tools, AI tools, agents, and Context grounding
- [Plugins](plugins.md) — bundles that add skills, MCP servers, and credentials in one step
- [MCP servers](mcp-servers.md) — connecting MCP servers, the Orchestrator catalog, and the third-party marketplace
- [Connections](connections.md) — UiPath Integration Service connections used by skills
- [Credential assets](credential-assets.md) — Orchestrator assets and credentials for automated tasks
- [Hooks](hooks.md) — running a shell command at a point in the agent's lifecycle
