---

Activepieces includes a built-in [MCP](https://modelcontextprotocol.io/) server that lets AI assistants build flows, manage tables, test automations, and more — all through natural language.

## Quick Start

### 1. Get Your Server URL

1. Go to **Settings** → **MCP Server**
2. Toggle the server **on**
3. Copy the **Server URL**

### 2. Connect Your Client

Add the URL to your MCP client config. Authentication is handled via OAuth — your client will open a browser to authenticate on first use.

```json
{
  "mcpServers": {
    "activepieces": {
      "url": "https://your-instance.com/mcp"
    }
  }
}
```

| Client | Config Location |
|--------|----------------|
| Cursor | `.cursor/mcp.json` (project) or `~/.cursor/mcp.json` (global) |
| Claude Desktop | `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\Claude\claude_desktop_config.json` (Windows) |
| Windsurf | MCP settings in editor preferences |
| Claude.ai | **Organization Settings** → **Connectors** → **Add** → **Custom connector** |

### 3. Start Building

Once connected, ask your AI assistant things like:

- *"Create a flow that sends a Slack message when a new row is added to Google Sheets"*
- *"Check my flow for any issues before publishing"*
- *"Create a Contacts table and add 3 records"*
- *"Show me the last failed run and what went wrong"*
- *"What Slack triggers are available?"*

## Tool Categories

Tools are organized into categories. **Discovery tools** are always available. Other categories can be enabled or disabled per-project in the MCP Server settings.

| Category | Description |
|----------|-------------|
| Discovery | Read-only tools for exploring flows, pieces, connections, tables, runs, and validation |
| Flow Management | Create, duplicate, rename, publish, and enable/disable flows |
| Flow Building | Add, update, and delete steps and triggers |
| Router & Branching | Add, update, and delete conditional branches |
| Annotations | Manage canvas notes |
| Tables | Full CRUD for tables, fields, and records |
| Testing & Runs | Test flows, inspect results, retry failures |

See the [Tools Reference](/mcp/tools) for the complete catalog with input schemas.

## Security

- **OAuth authentication** — secure, token-based authentication handled automatically by your MCP client
- **Credentials are never exposed** — connection secrets, API keys, and OAuth tokens are never returned by any tool
- **Project-scoped** — all operations are scoped to the authenticated project
- **Sensitive setup** — `ap_setup_guide` returns instructions for the user to configure connections in the UI, rather than handling secrets through MCP
