# What are MCPs?

## What is MCP?

**MCP (Model Context Protocol)** is a standard protocol that allows AI agents and workflows to connect to external tools and services.

## Benefits

✅ **No-Code**: Connect tools without programming ✅ **Secure**: OAuth and encrypted credentials ✅ **Extensive**: 2,673+ integrations available ✅ **Flexible**: Use in agents, workflows, and workforce ✅ **Reliable**: Built-in error handling and retries

## How MCPs Work

### In Agents

1. Add tools to agent configuration
2. Agent can call tools during conversations
3. Results returned to agent automatically
4. Agent uses data to respond intelligently

### In Workflows

1. Add integration nodes to workflow
2. Configure authentication
3. Map inputs and outputs
4. Execute as part of automation

### In Workforce

1. Assign tools to specific team agents
2. Agents use tools as needed
3. Share results across team
4. Coordinate tool usage

## Integration Types

### Pre-built MCPs (2,673)

Ready-to-use integrations for popular services:

* Communication (Slack, Email, Teams)
* Data (Google Drive, Sheets, Databases)
* CRM (Salesforce, HubSpot)
* Development (GitHub, Jira)
* And 2,600+ more

### Custom Integrations

Build your own:

* [API Call workflows](/workflows/triggers/webhook-triggers.md)
* [Connection providers](/integrations/connection-providers.md)

## Authentication

### OAuth 2.0 (Recommended)

* Most secure method
* No password sharing
* Granular permissions
* Automatic token refresh

### API Keys

* Simple setup
* Copy/paste key
* Stored encrypted
* Good for internal tools

### Basic Auth

* Username/password
* For legacy systems
* Encrypted storage
