Ideal Audience

• AI automation enthusiasts

STEP 1: Accessing Agent Builder

To start linking external tools, visit: platform.openai.com/agent-builder

From the homepage:

• Select Agent Builder from the left panel
• This opens the workspace for building workflows
• Click Create to build a new agent
• Alternatively, use a prebuilt template
• The Start node defines the trigger
• The Agent node handles logic and execution

STEP 2: Setting Up the Agent and MCP

Inside the builder:

• Add Agent Instructions, for example:
  “You are an assistant who creates a Google Form to collect feedback on weekly workshops.”
• Choose your model and reasoning level

• Click MCP Server, Third-Party Servers
• Select Zapier

STEP 3: Configuring Zapier MCP

Go to: mcp.zapier.com/mcpservers

• Click New MCP Server
• Select OpenAI as the client
• Assign a name (e.g., “OpenAI Server”)
• You’ll gain access to multiple apps

STEP 4: Linking API Keys

To connect everything:

• Open Connect in Zapier MCP
