Using toolkits in Nexus

What are toolkits?

Toolkits allow you to create groups of MCP servers that work together for specific tasks or workflows. Instead of connecting to all your available tools at once (which can confuse AI assistants), toolkits let you create targeted combinations optimized for particular use cases.

Why use toolkits?

When AI assistants have access to too many tools at once, they can struggle to choose the right ones. Toolkits solve this by creating focused, task-specific tool groups.

Create a toolkit

1. Click on Default Toolkit at the top left corner of your screen and select the +Create toolkit button.

2. Give your toolkit a descriptive name. This helps you and your team understand what the toolkit is designed for. The URL alias gets automatically created when adding a name.

Add or edit a toolkit

To add or edit a toolkit, open any toolkit and click Add from the list of available tools. To remove a tool, hover over any tool you’ve already added and click it again.

You can add or remove tools at any time.

Switch between toolkits

If you’re using Nexus Chat and have multiple toolkits, you can switch between them using the dropdown in the Nexus interface. Just select the toolkit you want to use from the toolkit selector in the top navigation.

Manage tool access

You have full control over what actions a tool can and cannot do. You can revoke app access instantly via a toggle by clicking on the tool in the directory. 

An LLM can only use the tools you make available to it, and it cannot override any parameters you’ve preconfigured.

Tip: If you need more detailed or specific guardrails, ask the LLM to list the guardrails it currently supports.

Add custom toolkit parameters

You can teach Nexus to use tools the way you prefer. 

If a tool, or set of tools, includes a parameter that should always be set to a specific value, you can prompt Nexus to preset it. Nexus will then automatically apply that preset every time it uses those tools. For example:

From now on, in this toolkit, always use property ID XYZ when using Google Analytics

Preset the log groups parameter to this list: [log-group-1, log-group-2, log-group-3] when executing log queries

Always use the production database connection for queries in this toolkit
