Toolkits Needed
You'll need access to these toolkits in your Arcade MCP Gateway:
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 16 specific tools this agent actually needs. This precision reduces risk and keeps your agent focused.
Create the gateway and copy your MCP URL
Click Create Gateway. Copy the MCP URL — this is all you need to connect to LangSmith!
https://api.arcade.dev/mcp/my-agent No tokens needed! Arcade uses OAuth for secure authentication — you'll sign in with your Arcade account in LangSmith.
