Toolkits Needed

Setup Guide
Sign up for Arcade
Create a free Arcade account to get access to MCP Gateway.
Create Arcade Account →Create a new MCP Gateway

Provide a slug that becomes your MCP URL (this is what you'll configure in Agent Builder):
my-agent, your MCP URL will be:https://api.arcade.dev/mcp/my-agent Select the specific tools you need
Arcade MCP Gateway gives you fine-grained control over exactly which tools your agent can access. Select these specific tools from the toolkits:
Why this matters: Instead of granting access to entire toolkits with hundreds of tools, you're selecting only the 10 specific tools this agent actually needs. This precision reduces risk and keeps your agent focused.
