Arcade.dev tools added to LangSmith Fleet

LangSmith Fleet has partnered with Arcade.dev to provide Arcade's 7,500+ agent-optimized tools through a single security gateway. Fleet's agents can now work across multiple tools like Salesforce, Notion, and Slack.

Arcade's MCP Gateway centralizes tool connections, reducing the burden of managing separate API integrations and authentication flows individually. You can create an organization-wide gateway, or configure custom gateways by team or use case.

The key point is that these are not simple API wrappers, but tools designed for agents to use effectively.

• Tool scope is narrowed around what agents actually do
• Consistent structure and descriptions improve tool selection
• Reduces misselection, hallucinated parameters, and unnecessary endpoint exploration in natural language contexts

On the security side, it supports per-user, session-scoped authorization, reflecting the permissions of the user the agent is acting on behalf of. In Fleet, you can choose between Assistants, which pass each user's own credentials, and Claws, which use fixed credentials for teams/services.

To get started, 60+ templates are provided for sales, marketing, support, and engineering, which you can use right away or use as a starting point to configure a new gateway.
