}Specialized in specific domains with access to relevant knowledge bases.
Can perform specific tasks and interact with external systems.
Focused on data analysis, reporting, and insights generation.
Enable Actions connected to your team's applications to let Agents automate work through the Model Context Protocol (MCP).
Actions are predefined functions that agents can execute to interact with external systems, perform tasks, and automate workflows.
MCP is a standard protocol that enables AI models to securely connect to external data sources and tools. Nexus uses MCP to provide a standardized way for agents to interact with your applications.
# Example MCP configuration
{
"mcp_servers": {
"calendar": {
"command": "npx",
"args": ["@modelcontextprotocol/server-calendar"],
"env": {
"CALENDAR_API_KEY": "your_api_key"
