Getting Started Tutorial

Build an AI tool to fetch your emails

👋 Follow this tutorial to build a tool to fetch your Gmail emails in under 5 minutes.

What we'll do:

1. Install the Pica MCP Server

2. Connect your Gmail account

3. Set up a starter project (Vercel AI SDK, LangChain, or MCP)

4. Add some rules for the LLMs to understand BuildKit

5. Prompt the LLM to build your tool

1

Install the Pica MCP Server

First, let's add the Pica MCP Server to your development environment. Select your preferred tool and follow the instructions.

In the Cursor menu, select "MCP Settings" and update the MCP JSON file to include the following:

MCP Settings JSON
{
  "mcpServers": {
    "pica": {
      "command": "npx",
      "args": ["@picahq/mcp"],
      "env": {
        "PICA_SECRET": "your-pica-secret-key"
      }
    }
  }
}

Note: Replace your-pica-secret-key with your actual Pica secret key from the link below.

Grab your API Key

Navigate to your Pica dashboard to access your API keys.

Connect your Gmail account

Now we need to connect your Gmail account so we can test our tool after we build it.

2. Set up environment variables

Create a .env.local file in the root directory:

.env.local
OPENAI_API_KEY=your_openai_api_key_here

3. Run the development server

npm run dev

4. Open your browser

Navigate to http://localhost:3000 to see the chat interface.

Add some rules for the LLMs to understand BuildKit

BuildKit Rules for Cursor

.cursor/rules/buildkit.mdc

Click the button below to copy the rules for Instant and paste them into .cursor/rules/buildkit.mdc in the root of your project.

✓

Verify Setup

You can verify setup by asking "What connections do I have in Pica?" - it should show your Gmail connection.

5

Prompt the LLM to build your tool

Copy this prompt to build the Vercel AI SDK tool:
