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
Navigate to MCP Gateway page in Arcade, then click Create 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 9 specific tools this agent actually needs. This precision reduces risk and keeps your agent focused.
