# Workspace chat

> Chat with Tracecat across your workspace, select tools and MCP integrations, and mention preset agents.

<Badge icon="github" color="gray" size="lg" shape="pill">Open source</Badge>

Workspace chat is a workspace-level assistant that is separate from the copilot inside each case. Open it from `Chat` in the workspace sidebar or as a side panel over the Tables pages.

## Set the default model

Go to `Organization > Settings > Agent`, connect a [provider](/agents/custom-llm-providers), and choose an organization default model. Until you set one, Tracecat disables the composer and links you to agent settings.

## Choose tools and MCP integrations

Select `Tools` to open the picker. Tracecat defaults are always included.

* In `Active capabilities`, `Cases`, `Tables`, and `Workflows` are on by default. Tracecat drops any tool your workspace role could not run itself, so a restricted role sees fewer.
* In `Add tools`, toggle individual tool groups on or off.

`MCP integrations` lists the servers your workspace configured itself, and `Connect an MCP server` adds one; see [MCP servers](/automations/integrations/mcp-integrations) to connect a remote or local one. Your workspace role needs `integration:read` to see the section.

The agent add-ons entitlement adds `Agent presets` to `Active capabilities`, as shown below, and the Tracecat-managed catalog connectors to `MCP integrations`.

## Mention an agent

<Badge icon="lock" color="blue" size="lg" shape="pill">Enterprise</Badge>

Focus the empty composer to show the `@ Mention agent` hint, then type `@` and select a preset agent from the list. Selecting the result sets that preset for the entire conversation, and the `@Agent name` text remains in the message you send.

The list keeps filtering as you type, including across the spaces in a name. It matches the agent name or its slug, which each row shows on the right.

Selecting a result is what binds the agent; typing a name as plain text does not.

A badge with the agent name replaces the hint until you clear it with `×`. A preset supplies its own tools, so `Tools` is unavailable while an agent is set.

Your workspace role needs `agent:read` and `agent:execute`. Without the agent add-ons entitlement, `@` opens the list with an Enterprise notice instead of agent names.
